i just installed same cam in my car, and it wont idle right, it burns real rich..its a 350 motor,76 cc heads, 60 over flat top pistons..did u have to do anything to get car tuned to cam? email me at dual455@aol.com 803/389-2537..steve
@vdawn36 Figure out your compression, sounds to me like it is a bit low for a performance cam. You need about 10:1 to make it work good. I used .125 dome pistons on my open chamber heads to get 9.8:1. Check out my video of the 55 with a comparable lunati grind.
Nice classic! Question on the crossover pipe... what other function does it have besides balancing the exhaust? Thanks! I personally like how it sounds on yours.
i have a chevy 350 block numbered 3970010 being prepped for my car, installing a aftermarket endurashine intake, thumper cam from summitracing, and undecided if im going holley or edelbrock but defenitely going 600. plan to go 2 1/2 inches on shorty headers dual exhaust and using super 40s mufflers.will this give me the sound yours makes? o and its going in a 59 impala 2 door hardtop, so does placing mufflers in certain spots along the exhaust pipe make it sound better? thanks, reyes.
@kenzo5716 my engine came with a stock quadrajet, should i just rebuild that? and after opening my engine i saw its a 4 bolt main. but had a guy tell me dont believe the hype, that theyre actually weaker than 2 bolt mains cause of placement of bolts. any truth to that? and is the thumper cam just for sound or does it actually increase performance?
@reyescarrillo Quadrajets are good carbs, but tricky to rebuild. If the carb works ok now, don't fool with is. If your engine is a 327 or larger, use an "out of the box" Holley 750cfm Vacuum secondary. You can get a good used one off ebay for cheap. Get one as close to new as you can afford or just get a new one. 4 bolt mains are stronger in all motors except the 400. However 2 or 4 bolt are both good engines no matter what. Forget thumper cams. The ISKY 270 mega Cam is good. 2000 stall conv.
There are 3 different stages on the "Thumpr" cam, maybe more now. I do know that the "mother-thumpr" and "big mother thumpr" both have close to, and over .500 lift w/ 107 degree of LSA. Good combo of performance and sound. I like the sound first personally.
@MrAss707 I have a group of guys I run with. Several use the Thumpr cams. I use Isky Mega cams. The Thumpr cam guys don't like running me, not even the rollers. I currently run an Isky 280 hyd with 1.6 rockers on the intake per Vizzard Racing suggestions. I Use a Victor jr w/2" spacer and 750 dbl pumper. Have ported Topline heads w/2.02 and 1.60 valves. I use a 30 degree back cut on valves. I use Hooker long tube headers, built turbo 350 w 3000 stall and 4.10 gears. Pulls 429 dyno hp
Small block stroker sounds like...those wind-up tight and those Th350s are plenty snappy.
Why the 30 degree back cut valve, better seal?
I just came up on a 1973 Chevy C10, shortbed stepper. Im about the 4th owner, very well takin care of and all the trucks history ( original COPO order doc, all tune-up, all parts/upgrades, ect) are in two binders. Came factory w/ a 1970 ss style 454, TH400, and 12 bolt rear. Ive only had the truck for about 2 months and it's pretty fun.
@MrAss707 Nope. It's a .060 over 350 squared and decked. Mega cams are Oval Track cams, make much more power than Comp cams. Just ask Joe Sherman Racing. trick doesn't work in all applications. But in certain cases, especially when using stock or production-style valves, this simple machining operation can be worth an amazing amount of increased flow.

@MrAss707 I had a pretty stout 383 stroker, Old style edlebrock RPM manifold/ with 2" spaer, built turbo 350 and 800 dbl pumper with a 3500 stall. Couldn't keep the tires from boiling. I ran a 292 Mega cam, long tube headers, dual 3" dynomax Race Bullets. and 3.73 gears. It was in a 1985 short bed fleet side. Sounds like the 73 C10 is a sweety. I have an 85. Mean sounding cams don't always bring the moolah home when the money is laid on the table at the old air port we run at.
@MrAss707 All factory vortec heads run a 30 degree back cut. I love your car. Wish I owned it. Had a blown 396 55 once with a 396. Too much for the street without tubbing about a foot on each side. It was a 4 speed. I should have used a glide.It would have helped. Tire boiling problem again. I could drive all over town only using 4th gear. LOL!
Sounds like you have a lot of fun when it comes to automotive.
My '73 needs a few items: Vacume Modulator for the 400, high-torque mini starter ( I still dont know the tooth count on the flywheel ) , the shift indicator dont work on the B&M mega shifter, it's just stuck in park but totally drivable, I have a new sterio system going in.....
All the metal is good, straight body, good glass, nothing missing, custom molded tailights I believe off a 64-66 mustang in the stepsides
@MrAss707 Modulators are easy. To see if it's bad for sure, pull vacuum line off, stick Q-tip inside it. When you pull it out if it has red tranny fluid on it, it's bad. If needing one, just pull old one straight out and stick new one in. They seem to always come set just right.for flex plate, big block has a 168 tooth.Shifter, pull it out, check for worn out bushings and missing carter or other locking pins. Oil everything. Get heavy duty flex plate, thicker. Others crack. Summit!
The guy whom sold me the truck mentioned the vac-mod and the vac-gauge does not work inside the truck, so very soon ima try that easy trick with the q-tip. Right now it's not shifting as snappy as it should, or could. I have an extra shifter, the "quick silver" also B&M, wondering if I could toss a part or two around ta get the "mega-shifter" working right.
@MrAss707 if vac-guage and modulator are both not workinhg, make sure they are not connected together. follow both lines closly. They may even be "teed" together. Sounds like a possible vacuum leak to me. On shifters, when bushings get worn things get misaligned/out of adjustment and a rod or something might even have dropped off.. I would pull it and go through it. You could try shifting parts around. Might work.
@MrAss707 Better bet yet, pull modulator hose and put a vac-gauge directly to it. It runs on full time vacuum. If shes a stocker or close, you should get around 20 inches of vacuum. Remind me later to give you some tips on re-curving distributor and a old time timing trick. Also, get somebody inside to floor gas peddle when not running and make sure your getting full throttle. Butter flys should be straight up and down.
From what I understand there are a few different types of vac-modulators, before i buy a new one I'll use your advice to check first although I am pretty sure the vac-mod is done. After the guy explained a large history of the truck to me, the first item he mentioned was the modulator, he said thats why the gauge dont work inside the cab
@MrAss707 put a vac-guage on modulator hose first. Look for around 20 inches of vacuum. If it ain't got it, you have a vacuum leak somewhere. Check all vacuum hoses carfully. Bend them and make sure they aren't cracked. Check where it hooks up, either to the carb or manifold. They are probably teed together somewhere. Then try another modulator if everything checks out. Do the simple things first. You don't want to just go out and buy a new modulator without these checks. Save money.
@MrAss707 Also, depending on type of carb. Be sure vacuum line (if connected to carb) is connected to correct port. It should be the lowest towards manifold. It is the one with full vacuum at idle. The other port is for the distributor hose.
@MrAss707 The other is "Timed Vacuum" which delivers vacuum only after the throttle is opened. It's also called the . Distributor port is usually located on the passenger side of the primary metering block, just above the idle mixture screw on Holleys. If your distributor is equipped with a vacuum advance, I strongly recommend that you use it. Tranny uses port that has full vac at idle.
I have an HEI distributor w/ vac-advance and Im pretty sure the line is hooked up. I think if I replace the old vacume modulator with a new part, as the former owner suggested the day we made the deal. I just picked up a new timing light, id like to check my timing too, and I want to get a summitracing, high torgue mini-starter. Santa Rosa Hydromatic has vac-modules for TH400s @ $25 and I may pick up some fresh line.
Hell yeah, i got a 1980 olds cutlass that im in the middle of rebuilding a 350 sbc that my brother put in before i bought the car from him, the motor was a half ass job and he threw the exhuast like a dumbass. Now im wanting the same sound, are u runnin straight pipe or u throw a cat in there? I was thinkin straight pipe with some super 40 before the rear end. Think i might get close to the same sound without the thump cam?
nice sound. how does this engine behave in city traffic with this cam? do you have enough low rpm "grunt" ? just asking because i'm putting together a mostly stock 350 and i like the "sound". the engine is going into a heavy car so i need drivability and torque. will i get that with a cam like yours?
That is the sound I am after for my truck I cant wait!!!!!!!!!!!!!! That sounds awesome I love that sound.......What do you have as far as stall coverter and the cam and heads

ive looked through the comments, and have been wondering was lift and duration it is. i have the same engine you do, same carb..etc. thanks and beautiful sounding.looking car
where did you buy your cam at? Or did you buy the engine with it already installed, and if you bought the cam separate how much did you spend on it? The reason I'm asking is because I have a 1985 Chevrolet Celebrity that I am currently in the process of restoring, but instead of keeping the original 151 Iron Duke Tech4 engine in it I am planning on dropping a 283 V8 with a thumper cam in it instead.
@killaskillz52 You wore the lobes off the cam in 30 min of run time? Yikes. Sounds like you didn't do the procedural steps to break the cam in. Probably why you didnt like the performance, lol. You need a good moly-based assembly lube on all the cam journals, lobes, and lifters. Then you need to top the engine off with a high zinc break-in oil, like Comp Cams makes After that, make sure your lifter pre-load is spot on, and the engine is ready to run 2500rpm for at least 20 min no less or else...
hey man very nice sound whats cam part number or size so i can find one im building a 61 chevy apache 10 pick/up any help would be great thanks great car man sweet ride
Hey I nerd a little help. I got the same cam as u do. But I don't know if I need springs or not. I have a goodwrench 350 260 hp with 350ft tq. Do I need springs.
you say its a crate motor so do you mean its stock? if so what size cam is that and did you have to replace the springs? im wanting a thumpr cam for my 1990 chevy 350/700r4. i just got done putting 2 1/2 true dual 40's no cats
Sounds good! I just ordered an American Thunder exhaust kit in 3" with Flowmaster super 40's for my 572 big block. Also ordered a set of Doug's Electric Cutouts. Check out my car on Facebook just search for Street Bully or google Street Bully 572
Love the sound. Am guessin it is a true dual with no crossover pipe? Where in your exhoust did you mount your mufflers? I am looking for a this same sound on my car and want to make sure. Thanks
You are guessing right, true dual 2 1/2 inches front to back, no crossover. Mufflers are right before the rear end where exhaust pipes bend and go over rear. Hope it helps, good luck and thanks for watching.
you can get the thumper cams from lunati mostly a 5k sometimes a little higher cam they just use lots of overlap etc but to me why have the sound if it doesn't run hard,, i have a comp roller that has a 298 dur, 246 at 50 109 c/l 598 lift. and sounds as good as it runs,, pulls like a bastard at 3-8k i shift at 7400
what do you mean, like you wouldn't be able to hear the cam? not true at all, i've run open headers on my truck while i was welding up my exhaust and i could still hear the cam and i only have a Lunati Voodoo idle-5000rpm cam
This video is the reason I went with the thumpr cam. Our set up is pretty close to the same except for heads and I'm still running a stock converter. Check out my videos and tell me what you think. Got to love that thumping sound!
Hey I finally got the cam put in my Monte, have you had any problems with it idling after its warmed up? Mine runs fine but stalls out at stop signs or red lights if i dont keep my foot on the gas a little and my power brakes will go out untill i get back up to speed.
Hey, no idling problems after is warmed up. I do have the same issue as you when at stop signs or red lights, mine wont stall but idles really low and I have to keep my foot on the gas just a hair. Power brakes don't go out on mine. I haven't had time for a fine tune session, right now it's very close to being tuned but I know maybe it's not there yet, I'm thinking maybe that's the cause and it will go away after that. Let me know what else you find out, thanks, Mike
i know its been a while but i had similar problems with a edelbrock performer rpm cam and it turned out to be a stall converter, not sure if you have stock stall or what but put one in where stall speed is about 200 rpm higher than the low end of you cam powerban
Big Cams need more initial timin, around 22-24 degrees that will fix you low rpm trouble and probably give you some powerbrakes back as well. Love the sound !
@QBANBELAIR your engine has a lot of vacuum is what it sounds like my Chevy blazer has a really big cam and does tend to do that because there is not allot of vacuum
@tpooleATL its because its loadin up with gas at the light try going to a performance coil and the brakes wont work because that big cam dont pull alot of vaccum
Now THAT is a true American Muscle Car. I love that rumble it has. I just bought a thumpr cam and am going to install it into my 99 Chevy Tahoe soon (350 vortec v8) I hope she'll sound as good. Keep it clean man, nice ride.
I just followed Comp Cams recommendations on how to break it in (included in shipping box), make sure you put assemb lube generously on all lobes and contact surfaces and change oil and filter after proper break in. Hope it helps, Mike
Idle is a nice thumping sound, wouldn't call it rough but it sounds great, turns a lot of heads and I get a lot of compliments and thumbs up. Watch the video of my friend driving it, it's idling there, just go to my videos and you'll hear it there. Thanks for watching, Mike
Ok thanks man, i went ahead and got the mutha thumpr. I just need to find an engine hoist and I'll get to work on installing it, I'll be sure to post a video of it
My engine is all stock, did not change springs. You need to check specs for yours before you pick your cam, some of these need bigger springs, thanks for looking, Mike
i just installed same cam in my car, and it wont idle right, it burns real rich..its a 350 motor,76 cc heads, 60 over flat top pistons..did u have to do anything to get car tuned to cam? email me at dual455@aol.com 803/389-2537..steve

where did you buy your cam at? Or did you buy the engine with it already installed, and if you bought the cam separate how much did you spend on it? The reason I'm asking is because I have a 1985 Chevrolet Celebrity that I am currently in the process of restoring, but instead of keeping the original 151 Iron Duke Tech4 engine in it I am planning on dropping a 283 V8 with a thumper cam in it instead.

@killaskillz52 You wore the lobes off the cam in 30 min of run time? Yikes. Sounds like you didn't do the procedural steps to break the cam in. Probably why you didnt like the performance, lol. You need a good moly-based assembly lube on all the cam journals, lobes, and lifters. Then you need to top the engine off with a high zinc break-in oil, like Comp Cams makes After that, make sure your lifter pre-load is spot on, and the engine is ready to run 2500rpm for at least 20 min no less or else...

You are guessing right, true dual 2 1/2 inches front to back, no crossover. Mufflers are right before the rear end where exhaust pipes bend and go over rear. Hope it helps, good luck and thanks for watching.

Hey I finally got the cam put in my Monte, have you had any problems with it idling after its warmed up? Mine runs fine but stalls out at stop signs or red lights if i dont keep my foot on the gas a little and my power brakes will go out untill i get back up to speed.
tpooleATL 2 years ago
Hey, no idling problems after is warmed up. I do have the same issue as you when at stop signs or red lights, mine wont stall but idles really low and I have to keep my foot on the gas just a hair. Power brakes don't go out on mine. I haven't had time for a fine tune session, right now it's very close to being tuned but I know maybe it's not there yet, I'm thinking maybe that's the cause and it will go away after that. Let me know what else you find out, thanks, Mike
QBANBELAIR 2 years ago
@QBANBELAIR
i know its been a while but i had similar problems with a edelbrock performer rpm cam and it turned out to be a stall converter, not sure if you have stock stall or what but put one in where stall speed is about 200 rpm higher than the low end of you cam powerban

Big Cams need more initial timin, around 22-24 degrees that will fix you low rpm trouble and probably give you some powerbrakes back as well. Love the sound !
