hey, my camaro has a slight problem, when you push harder then normal acceleration at time it just bog out and wanna shut off unless i let the gas pedal go...fuel lines, fule mpumps and fuel filters are ok....could i be time to overhaul the carb.? any advice?
@8137272424 you probably fixed this already, but yeah its the carb...from what it sounds like its running lean, which is why when you push it and the engine requires more fuel it chokes out.
i do that pretty often too. on most fuel injected cars, the fuel pump with turn on for a few seconds when you turn the key on to prime the system. it saves a little bit of cranking.
fuck a stick u dont want that garbage. get an automatic, like i said they'll take twice the beating. sticks are more for the fun of it. and young kids with hondas
depends on the trans.cheaper? easier to rebuild? not if its something like a t56. And reliable? a t5 like that came in the 3rd gens, a stock motor will break one of those easily. They arent very reliable at all. Sure there cool but its not a very decisive decision
Not really, Got a T56 swapped into a CV, and a T5 in a mustang, never had any trouble with the tranny untill about 400hp, A really shitty driver might break one with a stock motor, but it will be hard
Nice camaro... random question though. Does anybody know if they made IROCs with the manual trannies? I really like them its just that autos don't float my boat too well, lol.
tpi sucks for making power. Unless you have the cash for a stealth ram or one of the other manifolds. Otherwise they dont breathe very well. I would take a carb for a performance application for a tpi for a street car though. The torque is nice
i dont like carbs for some reson but i have found tbi is easy to work on and gives my camaro what it needs my gf has tpi and the only thing i dont like it that its hard to get to all the injector
i have the same steering wheel in my 89. but its not the stock wheel. its an rs which has the square horn button. i installed that wheel cause the original was missing. someone had an cheap aftermarket wheel on my car. i put a proper camaro steering wheel out of an iroc in my car.
That's right, you are sorry. If you really think your nickle and dime mods will make your car perform in the same ballpark as our 350tpi's, your dumber than I thought. Even other 305 owners on this page agree that they weren't made for performance, it seems like you're the only guy here making outragous claims about horspower and small bolt on mini-mods. Everyone here know that 305's, while they aren't bad engines, weren't made to go fast (like a 350 or 383). You need to stop making false claims
a 305 in its STOCK form was setup more for fuel economy than performance. the heads, exhaust, cam, and intake were restrictive. doesnt mean that a 305 cannot be made to perform, is it worth it? thats debatable. you need to spend 1,500+ to get 300 hp out of it. a crate 350 can be had for 1,500-2,000. personally i dont really care, my 305 has enough performance to be FUN TO DRIVE but its not a race winner. im going to run my 305 till it dies then get a 350.
I agree with you, I used to own a 305, and while it wasn't the fastest car on the road, it was fun to drive. When I got a 350 Iroc though, it was a night and day difference.I did the same thing you are planning to do, I drove that 305 till it fell apart then got a 350iroc. The point I was trying to make is there are alot of 305ers bragging about how fast there 305's are,how the beat modded 5.0's, how they can keep up with LT1's and just generally being insecure. 305's are ok,but not race winners
Dude, you're a real piece of work. You don't have any proof to back up your outragous claims of a HUGE horsepower increase from a standard tune up. Nobody on this page believes your B.S. I used to own a 305 that came stock with a carb, and it was slow. I've driven many different thirdgen f-bodies and 305's weren't performance oriented. You're an idiot and a liar.
I don't care what you say...I have an 88 IROC with a 305 TBI and I love it. It's loud, relatively fast, and gets 22 mpg on a mix. I just need a little more power after 70...my buddy's got an 07 Tundra with that 381hp 5.7L and I kick his ass until 70 then he gains a two length lead.
Sorry bro, but 305's and TBI aren't meant for performance, but you're right, they do probably get better fuel economy than my modded '87 350tpi. It's not your fault GM made 305's slow. If you drove a 350tpi iroc it would feel like a completely different car, you would be amazed.
I agree. The entire TBI set up was really based on longevity instead of performance. The 305 TBI was really a half assed attempt from Chevy to meet Smog regulations and compete with similarly equipped mustangs and 240sx's or z's or whatever the hell nissan had. The 350 TPI had 60 more hp and 75 more ft. lbs. of torque than the 305, but, unless I'm mistaken their stock 0-60 and 1/4 mile times were not too far off from each other.
I had an '84 berlinetta with a 305. in the berlinettas they only made 150hp. for 5L thats pretty sad. the car also weighed around 4000lbs. 305's CAN be made into performance engines, but then again what cant. the 305 though, is a disappointment on the whole. but then again, so are all the stock v8's in 3rd gens.
Yeah, the 305's & then entire lineup of 3rd gen Camaro engines were a disappointment mainly because GM was tryin' to meet emissions regulations, those engines have so many emission controls which restrict horsepower but like you said, those 305's can be made into performance engines, you take the stock heads & intake & mildly port them, remove the entire A/C system which will free at least 40hp off the crank, put some smog legal headers with the A.I.R. tubes & you'll get at least 250hp...
250hp is great compared to the 305's stock hp rating of 150hp, the 5.0L H.O. L69 305 was rated at only 190hp, & the 5.0L LB9 305 with Tuned Port Injection was rated at only 200hp, & the 5.7L. L98 350 was rated at only 220, if a person was do the mods I suggested, on top of adding an MSD distributor, the smog legal headers, mild heads & intake port, a mild computer tweak, you'll wake that 305 or 350 up!, & you haven't even made any changes to the rotating assembly yet!
yup. but then you got to ask yourself, is it worth doing to a 305? considering the modifications (cylinder heads, exhaust headers, etc.) are also a direct fit onto the 350's, you get more power gain from the same part. but its true, the 305 can be woken up. but then again, what cant? stupid emissions crap, my camaro is an '84 so its pre- '87 and i don't have to pass balls all for emissions, the lady tried to say I have to pass emissions and i was able to tell her to piss off and be right.
Most people would say no, that all the mods & work on a 305 isn't worth it, but to me, it is cuz I'm the type of guy that sees the potential in that part if it can be saved, even if I was filthy rich, I still would spend the money & rebuild the 305 just cuz I'm a genuine hot rodder when most people wouldn't even bother & drop in a whole, new motor, but I would rather drop in a 350 & go from there, but in my spare time, I would do all that work to the 305 & drop it in somethin' else.
thats an interesting perspective, I like it. In a way i'm sort of like that as well, but then again I bought my car w/o a motor so yeah. I want to build up a nice 383 or a high revving 400something. I'd end up doing what you would to to my 350 as if it were your 305. the same applies if I had any other car thats not a V8 or whatever. I would mess around with whats already there. and you're right, that is what hot rodding is all about.
i kind of like tbi though. its extremely dependable and very easy to repair. i have tbi i cars. i also own a 91 cavalier 2.2 TBI. the cavalier is at 141K miles and the camaro 305 TBI is at 172K. they both are still very dependable and neither one has ever left me stranded. if i ever put a 350 in my camaro i would run tbi. i would run a holley 675 CMF tbi unit and an eldebrock performer TBI unit though. the stock unit is restrictive.
If you guys look up the factory ratings for the 305s in the late 80s, there were like 4 engine ratings for the 305s... the TBI 305s only made 170hp w 255 ibs of torque, then u got the TPI 305s, which made anywhere from 195-230hp, with 280-320 ibs of torque.
they were rated at 165hp and 235ft-lbs of torque from the factory at the crank in your car made 29+whp and 55+ft-lbs of torque from stock at the crank (witch lowers the rear wheel numbers by 30-50) plus 100k miles of an idiot driving
you are trying to say your stock 305 makes 245-250hp and 330-350ft-lbs of torque?
i think not if it's stock shut the fuck up if not your still an idiot
Well that's because of traction. SRT4s make 250 horse and 250 lb/ft which is really good, they just have horrible traction. I sold my Dart and bought an '82 5.0 Mustang. I put a new crank and bearings in it and a 4bbl carb and intake manifold and it beats my Dart. It's got a 4-speed tremec (SROD) and I upgraded to an 8.8" rear end with 3.27 traction-lok. It's a fast little fucker. I don't regret selling that Dart at all. Videos of the Stang soon hopefully.
hey guys i have a 68 chevy camaro that runs 6.32 without spray in the 1/8 mile... it was my granpas car then he made it my dads 1st and my dad gave it to me recently to race.. it isnt street legal but i love camaros i plan to buy a stock 68 or so and make it fuel efficien and street legal..
With decent gears (3.23 or 3.55) and a shift kit as well as a 2200-2600 stall converter, you should be in the low 15/high 14 second range here in phoenix which is fast enough to run with 350Zs and SRT4s. My 318 has stock 1.74" and 1.50" valves, a .420/.442 - 204/212 @ .050" cam with 112 LSA, Eddy 4bbl carb and intake and Summit headers with 2.5" pipes w/ flowmasters and side exit and a built tranny and 3.21 gears. I'm doing 15.0ish and I pulled a fender on a 3rd gen 5.7 TPI Camaro.
Only one magazine was able to get 13.9 with an SRT4, the others got 14.1-14.2. Remeber, those are professional drivers in ideal conditions. Put a regular joe in the driver's seat and bring 'em here to phx and it's around 14.7-15.2. Same with 350Zs, i've seen it many times while at Speedworld. For 3rd gen Camaro's, 305/5.0 is 180 hp, 350/5.7 TPI is 240. Don't forget about traction, SRT4s have none. My neighbor's Sequoya can beat them in the 60 ft.
Also, i'm not talking bench-seat racing. You are giving me what magazine's and other people say, very optimistic information at that. I'm telling you what I see day in and day out at the dragstrip. I have many neighbors/friends with street/strip setups and race cars and we spend our weekends at Speedworld, sometimes Firebird, so i'm giving you real-life information. At least what I see here in Phx, anyway.
there basically a little bit faster than a 99-04 mustang gt...tell me how they run 12's stock..those gt's do low 14's to very high 13's with a good driver.
i have even driven one down the track (tho i ran 13.1 because i spun a bit off the line)
but the owner runs there weekly at 12.7-12.9
only mod are 235drag radials and intake and exhaust (radials can be cutting more than 0.1-0.2sec) and intake and exhaust just make like +5hp so about 0.05sec
Well i'm not gonna argue anymore but I find that unlikely because even if my Dart had an overdrive gear, I think it's top speed would be 130, and I can easily pull away from 305s at even 80 mph rolls. I stayed right next to a late '80s to early '90s Z28 with a 5.7 all the way to 100 when my gearing starts to put me into redline and I start slowing down (plus wind resistance is a big factor for my car.
I agree with you. I have a stock 89 305 and there is no way it could get up to 150 and I have the stock 2.73 gears. Mine is governed to 115 top speed but even if I took that off I HIGHLY doubt it could ever reach 150.
i have a 87 iroc-z 5.0tpi auto t-top. just some flowmasters,but i hit 130 from 1 onramp to the next its a nice strait with open freeway i coulda kept goin but braking becomes a issue for me so i slowed it back down 150 is beliveable 4 me because i was still gaining major momentum i got 3.23 gears tho
You might also note, that 1987 was the year they re-introduced the convertibles, which they DID NOT put the 350 TPI engines in (because the unibody twists like a beer can). They were available with either the throttle body injected 305, or the TPI (I think this is where "your math" is failing you...). So again, there goes another of your theories.
I can also tell you the diameter of the main journals and rod journals of a 305 or 350, as well as the cam specs, valve sizes, whether the piston pins are pressed or not, the torque on all the main caps and rod caps and the list goes on. I'm building a 305 right now for Christ's sake. Give me all the production facts you want, but don't argue with me about the schematics/mechanics/functions and repair operations of any automobile because you don't know the first thing about any of that.
Hey man, I'm thinkin' about rebuildin' my LG4 305 & maybe doin' a slight bore & stroke, no more than .030 inch on the bore, I already know the bore and stroke size of the engine, but I need the stock cam and heads specs, I think my heads are 1.84 intake, 1.50 exhaust, combustion chamber size is 63cc's I think, so holla atcha boy cuz that "Haynes" repair manual don't tell you nothin', I'm thinkin' about maybe keepin' my cast iron heads & maybe doin' a slight port match on them & the intake manif.
If the engine is original it doesn't need to be port matched. All that means is that the head ports are smaller than the intake ports on the manifold so when the air is exiting the manifold and traveling into the heads, it will hit a wall around the edges. The factory wouldn't assemble an engine with bigger intake ports than head ports so unless the intake has been swapped, the ports are already matched.
I have a buddy who has an Iroc-z (5.7L) with a 5-speed manual. It's a really rare car. I believe it's an '87. Its complelety stock and he has had it up to over 135 mph. Revolutionday1, can you confirm that it would be an '87? I think GM had a very limited production of actual 5.7's with manuals. Any other Iroc-z with a manual would have to be a 305.
Wow that was a bad mistake on your part being such a big Camaro enthusiast. I have a book fucking 10 feet away from me that has a few pages on the 1987 Camaro IROC-Z 5.7L. I guess you should write the publisher of that book as well as the IROC-Z web page and the GM corporation since you know what you're talking about but everyone else is wrong...
I had an '87 IROC-Z and my speedo went to 145mph and there was a small "Z28" logo where 150 should -theoretically- be (I had the needle wrapped past it on a couple of occasions). It was the 305 TPI, and I have yet to see another one with the same speedo.
A 305 could never on any occasion get to 150. They can't even pass 120. 305 Camaros are slow. They're an even race with a mid-'90s V6 Camaro. Either your Camaro had a WELL BUILT 350 and still had 305 badges or you're BSing. Starting in '87, IROC-Z's had 350s just fyi
Yeah, I'm gonna' have to call YOU on YOUR "BS'ing", pal. 1987 Camaro Z-28, with the IROC-Z package. 305 TPI motor (LB9). "120"?? Don't make me fucking laugh. My driver's side "blackout" flew off at at least 130. And where do you get your facts on the production? Because my centerbolt valve covers said otherwise. Stick to your "drumming", and have a nice day, jackass.
P.S.- I've also owned a (3.8L) V6 Firebird. "Mid-90's" (read: 1997), so there goes THAT theory, too.
First off, i've driven an '88 IROC with the 350 TPI and I know several people who have 305 Camaros, one is an '82 IROC, another is a '92 RS etc. Your speedometer may have hit 150 if you have 4.10 gears and you still have the stock speedometer cable drive gear, but there's no way you did even 130 with a 305. I've easily beaten all my friend's 305 Camaros and stayed even with the 350 TPI. Show me a video of you doing 150 and i'll believe you, then again idk if your speedometer is even correct.
4.10's (which to the best of my knowledge, never really "came factory" on the cars...) are an ACCELERATION (read: "holeshot") gearing. i.e. that would result in a LOWER top speed vs. say a 2.73 (which I didn't have, either).
P.S.- the highest/"lowest" rear gear from the factory in '87 was a 3.45 Posi. NOT 4.10's. You really don't know shit about dick, do you??
I was implying that your Camaro had aftermarket 4.10 gears with a stock speedo drive gear making the speedo read faster than you are actually going. you obviously can't understand that principle. You know alot about models and years and what was availible when but you know nothing about automotive theory/design/function and the design and operation of drivetrain parts.
Ok I stand corrected. That's not the point, though. The whole reason for this convo is because you claimed to have done 150 with a 305 Camaro which is very unrealistic. congrats for knowing lots about Camaros. Unfortunately you really don't know anything about the mechanics of any car, yet you keep talking down to me. Tell me what happens hydraulically, mechanically and electronically when "D" is selected on a 4L60-E. I can tell you right now.
If you want to have a nice street package for your 305, do this: Camshaft with about .450" lift and 210 duration @ .050" lift with LSA of 110-112. Take the factory 305 heads and have them resurfaced .010" and have the seats cut and 1.94" intakes and 1.60" exhausts installed, or just use 350 heads and mill them down until they have 63cc chambers. Factory intake and 4bbl carb work fine. Use full-length headers and 2.5" dual exhausts with high-flow cats and mufflers.
If you like talking about engine codes hear ya go: In 1987, the L89 (5.7 TPI) had 240 hp and ran 15.3 in the 1/4 mile. The same year, the LB9 made only 190 hp which puts it around 16.0-16.5 in the 1/4. You mean to tell me that your 190 hp 16.5 second Camaro could hit 150, yet a 250 hp 13.9 second SRT-4 weighing probably 500 lbs less can barely hit 150? And a '98 Cobra making 340 hp to the wheels can barely pass 150, but your 190 hp 305 can make it? Logic, reason and common sense all disprove you
I have a 5.0L LG4 in my 84 Monte Carlo, and I would say my top speed is about 115-125 with my TH350 transmission, and I believe I have 2.73 gears, but I wanna swap out the Turbo 350 for a maybe a 700R4 or I really want a T56 or Tremec TKO 5 speed and of course I would have to change my gears to at least 3.23 or 3.42 and put on a posi, cuz I have a "peg leg" out back and I want power to both wheels, I might even throw a locker differential out back...

I agree. The entire TBI set up was really based on longevity instead of performance. The 305 TBI was really a half assed attempt from Chevy to meet Smog regulations and compete with similarly equipped mustangs and 240sx's or z's or whatever the hell nissan had. The 350 TPI had 60 more hp and 75 more ft. lbs. of torque than the 305, but, unless I'm mistaken their stock 0-60 and 1/4 mile times were not too far off from each other.

I had an '84 berlinetta with a 305. in the berlinettas they only made 150hp. for 5L thats pretty sad. the car also weighed around 4000lbs. 305's CAN be made into performance engines, but then again what cant. the 305 though, is a disappointment on the whole. but then again, so are all the stock v8's in 3rd gens.
aleks6989 3 years ago
Yeah, the 305's & then entire lineup of 3rd gen Camaro engines were a disappointment mainly because GM was tryin' to meet emissions regulations, those engines have so many emission controls which restrict horsepower but like you said, those 305's can be made into performance engines, you take the stock heads & intake & mildly port them, remove the entire A/C system which will free at least 40hp off the crank, put some smog legal headers with the A.I.R. tubes & you'll get at least 250hp...
VayLoc310 3 years ago
250hp is great compared to the 305's stock hp rating of 150hp, the 5.0L H.O. L69 305 was rated at only 190hp, & the 5.0L LB9 305 with Tuned Port Injection was rated at only 200hp, & the 5.7L. L98 350 was rated at only 220, if a person was do the mods I suggested, on top of adding an MSD distributor, the smog legal headers, mild heads & intake port, a mild computer tweak, you'll wake that 305 or 350 up!, & you haven't even made any changes to the rotating assembly yet!
VayLoc310 3 years ago
yup. but then you got to ask yourself, is it worth doing to a 305? considering the modifications (cylinder heads, exhaust headers, etc.) are also a direct fit onto the 350's, you get more power gain from the same part. but its true, the 305 can be woken up. but then again, what cant? stupid emissions crap, my camaro is an '84 so its pre- '87 and i don't have to pass balls all for emissions, the lady tried to say I have to pass emissions and i was able to tell her to piss off and be right.
aleks6989 3 years ago
Most people would say no, that all the mods & work on a 305 isn't worth it, but to me, it is cuz I'm the type of guy that sees the potential in that part if it can be saved, even if I was filthy rich, I still would spend the money & rebuild the 305 just cuz I'm a genuine hot rodder when most people wouldn't even bother & drop in a whole, new motor, but I would rather drop in a 350 & go from there, but in my spare time, I would do all that work to the 305 & drop it in somethin' else.
VayLoc310 3 years ago
thats an interesting perspective, I like it. In a way i'm sort of like that as well, but then again I bought my car w/o a motor so yeah. I want to build up a nice 383 or a high revving 400something. I'd end up doing what you would to to my 350 as if it were your 305. the same applies if I had any other car thats not a V8 or whatever. I would mess around with whats already there. and you're right, that is what hot rodding is all about.
aleks6989 3 years ago
i kind of like tbi though. its extremely dependable and very easy to repair. i have tbi i cars. i also own a 91 cavalier 2.2 TBI. the cavalier is at 141K miles and the camaro 305 TBI is at 172K. they both are still very dependable and neither one has ever left me stranded. if i ever put a 350 in my camaro i would run tbi. i would run a holley 675 CMF tbi unit and an eldebrock performer TBI unit though. the stock unit is restrictive.
ad356 3 years ago
If you guys look up the factory ratings for the 305s in the late 80s, there were like 4 engine ratings for the 305s... the TBI 305s only made 170hp w 255 ibs of torque, then u got the TPI 305s, which made anywhere from 195-230hp, with 280-320 ibs of torque.
Pracerdohczx2 3 years ago
hahaha not with a 305 they are by far the shittiest of the shitty american engines
and on top of that they were dogs from the factory and it was not somthing that oil,filters,or "tuning" can change more than 8-10hp max
for a 305 to put out that kind of power it would need a cam,heads,10.5-11:1 pistons,750cfm carb,intake manifold,headers,a crank and posssibly more
if you just have what you mentioned then anything more than 110whp is bullshit
0to60in16seconds 3 years ago
you need more gas
jackmitchell123 3 years ago
bullshit!!!!!
they were rated at 165hp and 235ft-lbs of torque from the factory at the crank in your car made 29+whp and 55+ft-lbs of torque from stock at the crank (witch lowers the rear wheel numbers by 30-50) plus 100k miles of an idiot driving
you are trying to say your stock 305 makes 245-250hp and 330-350ft-lbs of torque?
i think not if it's stock shut the fuck up if not your still an idiot
also srt4's make like 235ft-lbs stock at 1600rpm
0to60in16seconds 3 years ago
Well that's because of traction. SRT4s make 250 horse and 250 lb/ft which is really good, they just have horrible traction. I sold my Dart and bought an '82 5.0 Mustang. I put a new crank and bearings in it and a 4bbl carb and intake manifold and it beats my Dart. It's got a 4-speed tremec (SROD) and I upgraded to an 8.8" rear end with 3.27 traction-lok. It's a fast little fucker. I don't regret selling that Dart at all. Videos of the Stang soon hopefully.

With decent gears (3.23 or 3.55) and a shift kit as well as a 2200-2600 stall converter, you should be in the low 15/high 14 second range here in phoenix which is fast enough to run with 350Zs and SRT4s. My 318 has stock 1.74" and 1.50" valves, a .420/.442 - 204/212 @ .050" cam with 112 LSA, Eddy 4bbl carb and intake and Summit headers with 2.5" pipes w/ flowmasters and side exit and a built tranny and 3.21 gears. I'm doing 15.0ish and I pulled a fender on a 3rd gen 5.7 TPI Camaro.

0to60in16seconds 3 years ago
Only one magazine was able to get 13.9 with an SRT4, the others got 14.1-14.2. Remeber, those are professional drivers in ideal conditions. Put a regular joe in the driver's seat and bring 'em here to phx and it's around 14.7-15.2. Same with 350Zs, i've seen it many times while at Speedworld. For 3rd gen Camaro's, 305/5.0 is 180 hp, 350/5.7 TPI is 240. Don't forget about traction, SRT4s have none. My neighbor's Sequoya can beat them in the 60 ft.

Also, i'm not talking bench-seat racing. You are giving me what magazine's and other people say, very optimistic information at that. I'm telling you what I see day in and day out at the dragstrip.

At least what I see here in Phx, anyway.

high 12's in a 350z??!? wth a 150 shot? LOL
there basically a little bit faster than a 99-04 mustang gt...tell me how they run 12's stock..those gt's do low 14's to very high 13's with a good driver.
Junglemonkey1457 3 years ago
they run high 13's all day
i have even driven one down the track (tho i ran 13.1 because i spun a bit off the line)
but the owner runs there weekly at 12.7-12.9
only mod are 235drag radials and intake and exhaust (radials can be cutting more than 0.1-0.2sec) and intake and exhaust just make like +5hp so about 0.05sec
0to60in16seconds 3 years ago
i dont see it...i see low 14's and sometimes a high 13...
Junglemonkey1457 3 years ago
Well i'm not gonna argue anymore but I find that unlikely because even if my Dart had an overdrive gear, I think it's top speed would be 130, and I can easily pull away from 305s at even 80 mph rolls. I stayed right next to a late '80s to early '90s Z28 with a 5.7 all the way to 100 when my gearing starts to put me into redline and I start slowing down (plus wind resistance is a big factor for my car.
gtdrummerdude 3 years ago
I agree with you. I have a stock 89 305 and there is no way it could get up to 150 and I have the stock 2.73 gears. Mine is governed to 115 top speed but even if I took that off I HIGHLY doubt it could ever reach 150.
CamaroTBI 3 years ago
i have a 87 iroc-z 5.0tpi auto t-top. just some flowmasters,but i hit 130 from 1 onramp to the next its a nice strait with open freeway i coulda kept goin but braking becomes a issue for me so i slowed it back down 150 is beliveable 4 me because i was still gaining major momentum i got 3.23 gears tho
indulgence1988 3 years ago
You might also note, that 1987 was the year they re-introduced the convertibles, which they DID NOT put the 350 TPI engines in (because the unibody twists like a beer can). They were available with either the throttle body injected 305, or the TPI (I think this is where "your math" is failing you...). So again, there goes another of your theories.

*whoops, 305 carb (LG4) with the automatic slushbox or the 305 TPI (LB9) with a 5-speed.
revolutionday1 4 years ago
I can also tell you the diameter of the main journals and rod journals of a 305 or 350, as well as the cam specs, valve sizes, whether the piston pins are pressed or not, the torque on all the main caps and rod caps and the list goes on. I'm building a 305 right now for Christ's sake. Give me all the production facts you want, but don't argue with me about the schematics/mechanics/functions and repair operations of any automobile because you don't know the first thing about any of that.
gtdrummerdude 4 years ago
Hey man, I'm thinkin' about rebuildin' my LG4 305 & maybe doin' a slight bore & stroke, no more than .030 inch on the bore, I already know the bore and stroke size of the engine, but I need the stock cam and heads specs, I think my heads are 1.84 intake, 1.50 exhaust, combustion chamber size is 63cc's I think, so holla atcha boy cuz that "Haynes" repair manual don't tell you nothin', I'm thinkin' about maybe keepin' my cast iron heads & maybe doin' a slight port match on them & the intake manif.
VayLoc310 3 years ago
If the engine is original it doesn't need to be port matched. All that means is that the head ports are smaller than the intake ports on the manifold so when the air is exiting the manifold and traveling into the heads, it will hit a wall around the edges. The factory wouldn't assemble an engine with bigger intake ports than head ports so unless the intake has been swapped, the ports are already matched.
gtdrummerdude 3 years ago
No, yeah, I'm already knowin' the heads and intake are already port matched, I was meaning slightly enlarging the ports on the heads and intake
VayLoc310 3 years ago
I have a buddy who has an Iroc-z (5.7L) with a 5-speed manual. It's a really rare car. I believe it's an '87. Its complelety stock and he has had it up to over 135 mph. Revolutionday1, can you confirm that it would be an '87? I think GM had a very limited production of actual 5.7's with manuals. Any other Iroc-z with a manual would have to be a 305.

Wow that was a bad mistake on your part being such a big Camaro enthusiast. I have a book fucking 10 feet away from me that has a few pages on the 1987 Camaro IROC-Z 5.7L.

myroccz28 4 years ago
I had an '87 IROC-Z and my speedo went to 145mph and there was a small "Z28" logo where 150 should -theoretically- be (I had the needle wrapped past it on a couple of occasions). It was the 305 TPI, and I have yet to see another one with the same speedo.
revolutionday1 4 years ago
A 305 could never on any occasion get to 150. They can't even pass 120. 305 Camaros are slow. They're an even race with a mid-'90s V6 Camaro. Either your Camaro had a WELL BUILT 350 and still had 305 badges or you're BSing. Starting in '87, IROC-Z's had 350s just fyi
gtdrummerdude 4 years ago
Yeah, I'm gonna' have to call YOU on YOUR "BS'ing", pal. 1987 Camaro Z-28, with the IROC-Z package. 305 TPI motor (LB9). "120"?? Don't make me fucking laugh. My driver's side "blackout" flew off at at least 130. And where do you get your facts on the production? Because my centerbolt valve covers said otherwise. Stick to your "drumming", and have a nice day, jackass.
P.S.- I've also owned a (3.8L) V6 Firebird. "Mid-90's" (read: 1997), so there goes THAT theory, too.
revolutionday1 4 years ago
First off, i've driven an '88 IROC with the 350 TPI and I know several people who have 305 Camaros, one is an '82 IROC, another is a '92 RS etc. Your speedometer may have hit 150 if you have 4.10 gears and you still have the stock speedometer cable drive gear, but there's no way you did even 130 with a 305. I've easily beaten all my friend's 305 Camaros and stayed even with the 350 TPI. Show me a video of you doing 150 and i'll believe you, then again idk if your speedometer is even correct.
gtdrummerdude 4 years ago
Hey...guess what, dipshit- NO SUCH THING AS AN '82 IROC-Z!!!! 1985 was the 1st year. You suck at this. You should just stop, really.
revolutionday1 4 years ago
4.10's (which to the best of my knowledge, never really "came factory" on the cars...) are an ACCELERATION (read: "holeshot") gearing. i.e. that would result in a LOWER top speed vs. say a 2.73 (which I didn't have, either).
P.S.- the highest/"lowest" rear gear from the factory in '87 was a 3.45 Posi. NOT 4.10's. You really don't know shit about dick, do you??
revolutionday1 4 years ago
I was implying that your Camaro had aftermarket 4.10 gears with a stock speedo drive gear making the speedo read faster than you are actually going. you obviously can't understand that principle. You know alot about models and years and what was availible when but you know nothing about automotive theory/design/function and the design and operation of drivetrain parts.
gtdrummerdude 4 years ago
Ok I stand corrected. That's not the point, though. The whole reason for this convo is because you claimed to have done 150 with a 305 Camaro which is very unrealistic. congrats for knowing lots about Camaros. Unfortunately you really don't know anything about the mechanics of any car, yet you keep talking down to me. Tell me what happens hydraulically, mechanically and electronically when "D" is selected on a 4L60-E. I can tell you right now.
gtdrummerdude 4 years ago
That's right, the IROC package didn't come out until 1985....
VayLoc310 3 years ago
If you want to have a nice street package for your 305, do this: Camshaft with about .450" lift and 210 duration @ .050" lift with LSA of 110-112. Take the factory 305 heads and have them resurfaced .010" and have the seats cut and 1.94" intakes and 1.60" exhausts installed, or just use 350 heads and mill them down until they have 63cc chambers. Factory intake and 4bbl carb work fine. Use full-length headers and 2.5" dual exhausts with high-flow cats and mufflers.
gtdrummerdude 3 years ago
If you like talking about engine codes hear ya go: In 1987, the L89 (5.7 TPI) had 240 hp and ran 15.3 in the 1/4 mile. The same year, the LB9 made only 190 hp which puts it around 16.0-16.5 in the 1/4. You mean to tell me that your 190 hp 16.5 second Camaro could hit 150, yet a 250 hp 13.9 second SRT-4 weighing probably 500 lbs less can barely hit 150? And a '98 Cobra making 340 hp to the wheels can barely pass 150, but your 190 hp 305 can make it? Logic, reason and common sense all disprove you
gtdrummerdude 4 years ago
The LG4 topped out around 125.
There are vids on here of stock 3rd gens hitting well into the 130s.
150 is pretty unlikely, but any 305 with decent gearing could hit from 125-140 stock or with light modding.
stingray222 4 years ago
I have a 5.0L LG4 in my 84 Monte Carlo, and I would say my top speed is about 115-125 with my TH350 transmission, and I believe I have 2.73 gears, but I wanna swap out the Turbo 350 for a maybe a 700R4 or I really want a T56 or Tremec TKO 5 speed and of course I would have to change my gears to at least 3.23 or 3.42 and put on a posi, cuz I have a "peg leg" out back and I want power to both wheels, I might even throw a locker differential out back...
