Chevy 350 sbc Lunati BMII cam Edelbrock intake duals glasspacks idle and rev

[chevyfeen86]

This may be the cam I'll go with when I build my stroker

[ChevyTwins]

I own an 83 c10 with the same setup besides the 4.10 gears and the tbi mine has a carb. And I was very happy with the lunati cam however I do run 1.6 ratio rocker arms And I to am 16 years old.

[77z2the8]

Nice truck and sound I love those old school Chevys

[deanschool]

i have a 390 (i know its a ford) but i was wondering what you think of the cams lift and duration and such? i was gonna get the BMII with the 300/300 duration. woudld it lope more??? im 16 and kinda learning the ins and out of this. the truck would be used for cruising the street (not really a DD) and racing (drag)

[krazykraka777]

@deanschool I'm not sure of the exact cam you are talking about but if its 300 degrees of duration it should lope like my truck. Lobe separation angle and intake/exhaust overlap have a lot to do with lope as well. The less lobe separation and more overlap the lopier it will be, but this also affects performance. I am by no means an expert but I was pleased with Lunati products I'm sure one of their staff would be able to help you choose the most appropriate camshaft to accomplish your goals.

[chevells]

Love this cam, running mine in a sbc 307. sounds like a 350, i did all the motor work my self, im only 16. Will post a video of it soon!

[krazykraka777]

@chevells Good job man keep it up. I'm glad to see more young people wrenching on American cars.

[81montemitch]

are you happy with lunati cams?building a street motor and would like some info on some good cams

thanks

[krazykraka777]

@81montemitch I was very pleased with Lunati. Good quality product, power band was spot on with their claim.

[Bullett1971]

is that a stock cam or upgrade to like a mthr thmpr?

[krazykraka777]

@Bullett1971 It's a Lunati Bracket Master II cam. .458" lift intake and exhaust and 218deg duration at .050" lift.

[Bullett1971]

@krazykraka777 thanks man

[JetForceF22]

@krazykraka777 You don't happen to have a part number do you?

[krazykraka777]

@JetForceF22 At Summit Racing Equipment its LUN-00016LK

[JetForceF22]

@krazykraka777 Sweet, thank you very much!

[kmk45]

purple hornies are amazing

[scuddigi]

wow I got that same engine and rear end in my caprice that cam was it oo lopey for the vacuum and you said the pressure made it lean you ever fix it? How?

[krazykraka777]

@scuddigi It needed a bigger throttle body (TBI) if it was carbed it would have been just a matter of throwing a bigger carb on it. TBI throttle bodies aren't cheap and the biggest I ever could find was made by Holley and was 670cfm. I never bought it though, all I did was throw an adjustable fuel pressure regulator on it and crank it up to 18psi which helped but it still leaned out above 4500-5000RPM. Plus the computer tuning is a pain.

[kenzo5716]

@krazykraka777 you can get a throttle body for a big block from a salvage yard. My brother did this and he also added a 1 inch spacer. He runs an Isky 280 Mega cam and the truck really gets with the program.

[krazykraka777]

@kenzo5716 Yeah at the time I couldn't find one at a reasonable price (I was 17). I did have a 1" spacer on mine though. I would probably have a bigger throttle body on it by now but I sold it several years ago.

[YoungerPrice]

Which pulley is for the smog?

[krazykraka777]

@YoungerPrice The smog pump was about midline on the motor and to the left on this truck. There should be a sticker somewhere under the hood with a diagram though.

[puppy2334]

That truck had the hose for the air pump that went right in to the stock air intake right???? if sooo where did you mount it on the after market air intake????

[krazykraka777]

@puppy2334 Which hose exactly are you talking about? I deleted the smog pump so I didn't have to deal with any of that stuff and the intake was made for TBI engines so everything else pretty much fit just like stock.

[puppy2334]

@krazykraka777 I was talking about the smog pump. I hate having that shit on the truck cause of stupid PA innspection. Nice truck you have there.

[krazykraka777]

@puppy2334 Yeah I live in AL so no inspections for me :)

[foxrider166]

Motor sounds good and cammed up, now you need to lift or lower your truck. I go with a nice lift.

[foxrider166]

Motor sounds good and cammed up, now you need to lift or lower your truck. I go with i nice lift.

[JetForceF22]

When you ran this cam did you have to get rockers to accommodate the larger cam or did you leave the swirl port heads stock?

[arizonaresident1]

@JetForceF22 The only time you would need to change rockers is getting rid of stamp ed steel for high spring pressure or go to roller rockers for horsepower increases.

You're going to need to change the springs to match the cam.

[JetForceF22]

Okay thanks for the information I'll keep that in mind

[jayguy173]

can i barrow your engine for my f body

[krazykraka777]

@jayguy173 ha ha sure... if you can find the guy who bought the truck from me and steal it.

[bamaslamma1003]

Small block Chevy with a big cam. Beautiful music!

[jayhawk110]

Was there anything special you had to do to the tbi? To make it run right?

[krazykraka777]

I had to buy an adjustable fuel pressure regulator. Stock the TBI 350's were around 13-14psi fuel pressure I had to turn it up to around 18psi and it was still lean. In hindsight I wouldn't build a TBI like that. If possible just buy an older truck with a carb. Much easier because you don't have to deal with computer tuning.

[ExcessiveForce82]

Vortec heads were the beginning of the roller blocks in fullsize pickups in 96.

I have a 284 bracketmaster cam in my 302 mustang and it sounds pretty good.

I think it has .488 lift for the SBF`s.

[krazykraka777]

Yeah there were several Bracketmaster cams for SBC I just went with the small one because I hauled a trailer and the RPM range was 1500-5200 which worked well with my heads and intake as far as torque curve is concerned. Stills sounds mean in my opinion.

[krazykraka777]

Sorry, I meant to reply and I accidentally removed your post. Yeah, I wrote the description when I was like 15 and wasn't that bright. The heads were casting 10110810 '93-up swirl ports.

[09sgraves]

i jst bought this cam kit and im putting it in this sat in my 94 5.7 silverado. wth hedman headers and flowmaster 40's im hoping its gunna sound b.a.

is there any modifications u had to do like changing the distributor gear or getting a high stall converter?

[krazykraka777]

@09sgraves i didn't have to do anything. you will require computer reprogramming and extensive tuning though.

[krazykraka777]

If anyone was wondering, top speed was around 133 MPH and yes, I did every bit of it. Anyone else ever done over 130 MPH in a 3/4 ton pickup?

[deving68]

I have a 93 chevy 1 ton single wheel with the 454 TBI and ive done 140 tops. I'm surprised it didn't wobble apart.

[krazykraka777]

What trans and rear gear are you running? My truck was redlined at 5750 RPM at 133.

[deving68]

I have 3:16 gears and the 4L80-e tranny. My truck redlined at 5200-5300, it didnt have no more to offer. But also to mention just because I did that speed doesn't mean the trucks fast it took it awhile to get up there

[krazykraka777]

The gears and trans explain it. You have overdrive and a highway gear set. I had a 3spd auto with 3rd gear ratio of 1:1 and 4.10 gears. Yeah my truck would get up to top speed pretty quick it just ran out of gear.

[catburner]

nice ! where did you get those valve covers?

[krazykraka777]

summit racing

[dbzgt545]

NEED A motor like that in my crusher. Awesome job buddy.

[lespaul12001]

did you notice a increase in power with the edelbrock performer intake manifold?

[krazykraka777]

I added the intake along with several other parts and I did notice a significant power gain but who's to say how much was the intake? Sorry I can't be more help

[krazykraka777]

Holley also makes a 670 cfm TBI, but its about $450 and I haven't heard any feedback on it.

[kenzo5716]

For anyone wanting to use a TBI with a sbc setup like this, you need to go to a salvage yard or ebay and get one for a 454. it will bolt right on and has much more flow. hope this helps out.

[dunn98632]

cool truck and someone that knows about cars i like it

[19jody72]

Does it still have the lope once it is warmed up?Thats has to be the best sounding cammed TBI I ever heard!!I suppose you dont have the part number?

[krazykraka777]

It did yes, i rebuilt the engine with a smaller cam then sold the truck. I don't have the part number but you can find it in summit or jegs or on their websites. Just look for Lunati Bracket Master II for small block chevy. Its the one with 284 deg of advertised duration (218 @ .050) and .458 lift. It is a single pattern cam.

[NoLongerFooled]

Why did you sell it?

[JetForceF22]

This is a cam for the Long Block correct?

[krazykraka777]

Fits 262-400 SBC

[JetForceF22]

The Small Blocks are offered in the Short Block 350 and on the more recent models Truck Long Block 350, Does a standard cam fit both a short and long block or is there no difference in cam length?

[krazykraka777]

Short block and long block is just a term gearheads use to describe if it is a complete engine or just a block and rotating assembly. They are the same size.

[krazykraka777]

Just be sure the engine you are using it in wasn't originally equipped with a roller cam or you will have to find a retro-fit kit to make the cam work as it is not a roller but a flat tappet cam.

[JetForceF22]

Well my truck is a 95 350 TBI. As far as I know the truck does not come factory equipped with a roller cam, to my knowledge GM started doing that with the vortech engines, but then again I can be wrong.

[krazykraka777]

Yeah, to the best of my knowledge factory roller cams in the 350 started in '96 with the introduction of the Vortec 350 so you should be good to go.

[bigchevy80]

Roller cams were used from '87 up...

[krazykraka777]

I had a '87 and a '91 350 both were hydraulic flat tappet.

[JetForceF22]

In the Chevy Trucks the engines used a flat tappet cam until 96. However the 87-95 trucks do come with the provisions for a roller cam, they just don't have one.

[krazykraka777]

carb would be cheaper

[JetForceF22]

Thats a throttle body?? Did you have to change the lifters and all that with the cam? I also have a question about the rear end gears too if you would mind answering them for me, thanks for your time.

[krazykraka777]

yes its a throttle body i wouldn't recommend using it if possible it really limits potential and yes new lifters should always be used when you change a cam. ask away about the gears

[JetForceF22]

Okay thanks for that- I have a 95 Chevy K1500 4x4, I want to put 4.10's instead of 3.73's, the truck maxes at 100, (even with the OD), my tranny is the 4L60E, Now if I put 4.10's in will it max at 80 or 85, whatever the 3rd speed ratio ends at, or will the OD shift to go to 100 till the rev kill?(which is at 100) This has been my question and main reason why I have not switched over to the 4.10's yet. Thanks for your help by the way

[19jody72]

How in hell did you get a tbi motor to act right with that cam?(sound) got a part number? sounds great

[krazykraka777]

don't remember the part number for the cam but you can find it in summit racing or jegs. and honestly i didn't do anything with the cpu it just worked the first time i cranked it

[styl0us]

When you first started to back away from the truck, that cam made it sound like galloping horses. Nice work on the truck. I love the sound. I wanna get a Lunati cam for my 01 Silverado, just don't know which one to get.

[krazykraka777]

I did when I had it. It stopped fine, took some pressure on the pedal though. It's worth the power and it will still stop as good as stock just take more muscle.

[1234quinn123]

i hav a same exact truck but i dont know if mines a custon deluxe or a silverado.i got same exact gauges and motor.what kind of valve covers u got on it?

[buickbeasty]

did the throttle body spacer give u more power at all is it worth the little bit it costs

[oldchevyw]

i bought an 87 last year with a 305 and i'm pulling my 350 out of my monte for in it,it pushes around 400 hp the way i have it set up but i'm keeping my throttle body and all the emissions on the truck,it only has 63000 miles on it but the 305 is a pile of junk metal

[bhunt31]

my bad, I apologize for that.

[bhunt31]

Yeah, I noticed the TB tucked way up under there after I posted that message. Didn't see any other sensors, so at first glance it looked like he took all the TB stuff out.

[bhunt31]

about the exhaust...I'm running 3" pipes with Flowtech Afterburner mufflers and Hooker long tubes up front on my 84 Silverado...I love the sound, very deep. I'm running a 292H Comp cam in mine.

[supertahoe95]

hey did you do anything to your computer to run that cam?

[bhunt31]

computer?  seriously? what on that engine tells you it's computer controlled?

[dimedarkness]

Go order you a RCI or Jegs vacuum reserve tank. It's like 45 bucks and works great.

[dimedarkness]

One question to make sure for me self before ordering... How is your vacuum on the brakes. When you romp it about 100mph and try to stop... can you?

[krazykraka777]

it don't stop like it used to, but its not too bad.

[erk409]

i like it, i have the same engine and want the same exhost set up... maybe bigger pipes.

[krazykraka777]

yeah, if i were to do it now i would use at least 2 1/2" pipe

[tamapalagi]

i love the combo tell me how it runs. i think lunati cams are the best cams

[krazykraka777]

runs great and lunati does make some wicked cams
