BEST Sounding Cam for Small Block Chevy CRATE motors (Thumpr Cams?) 

Thank you, I bet that thing sounds awesome with 12:1. I have one of those cross ram intakes edelbrock made back in the day,

Big chamber heads doubt you have anywhere near 12:1

Big chamber heads, 12:1 compression, and pump gas? I smell BS. Unless you're running domed pistons, you're not making 12:1 with big chamber heads. And anything higher than 11:1 needs at least a race gas mix to not ping like hellmin warm weather

Thank you very much!!!!

Me too, I need to get this car finished lol

These are Brand new that came out of a new never ran crate engine that still had the assembly lube on them. There actually in my motor I put together for my 65 c10. I figured there better than the crappy new ones.

Probably around 900 to 1000

Thank you!!!!!

Thank you!!!!!!!! I think they recommend 2500+ on the stall. We have a 25 or 2800 on ours I can't remember exactly, just a hair over stock.

If your going to race it you get a custom converter ! Not as critical on the street !!! There are a lot of variables to choosing a converter if it's made just for your typical application !!! Mine was custom but racing only !! In the early 90s and I got it cheap for only 944$ ! Weight tire highth gear ratio trans type suspension type cubic inch compression cam card intake carb head details header size type of ignition everything !!! ATI and TCI are the best companies out there !! When I raced the most widely used was named appropriately the treemaster I think was ATI !!! Not cheap by any margin but mine was a high flash at 6300 rpm flash 8 inch !!! Consistent 60 fts on a good weather day 1.28 to 1.30 !!! On the street you want a pro street converter !! Race converter promote a lot of heat !!! A good trans cooler would be advisable !!! High heat is a converter killer !!! The hotter it is the more slip you'll have !!

We haven't driven it much to really tell, we mainly chose it for the sound but im sure it will improve some. As for the timing its still around 12 for now till we get her out and burn up the road. Thanks for watching !!!

Ill have to check that one out!!!!

Thats a lame cam

@@Jay-fb2lv How so? Better choice for a st car than these too big "gotta lope" cams.

I think factory is around 1800 stall. The way to tell roughly is look at your tachometer and see what rpm ut starts to move at and that will roughly be your stall. So if it starts moving at 2000 its probably 1800 to 2000 stall.

Thank you, they are like house brand from jegs, kinda like a 2 chamber flowmaster knock off, ill put a link to my video on my 65 c10. It has the same ones and I have a link in the description of that video below. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nsgQSBPGhhw.html

Yeah its a bone stock gm crate motor and seems to work pretty good. I haven't had any trouble so far. As for the cam they are great but there lifters, ive heard are junk now. So I just bought the same cam for my 65 c10 but im gonna use someone else's lifters. But my opinion there is not a better sounding cam around for stock engines.

Comp cams 272 cam ! .454 lift with a duration right at the edge !! This is as high as you can go without going aftermarket parts !! Has a nice racy idle and makes good power without changing anything !! If it see me I would still put better springs in it to get the true rpm out of it ! It would be a I believe a 6000- 6200 rpm cam but probably better at 5500-5800 !! 3.73 gears would work well with about 9-9.5 to 1 compression about 34 - 36 degrees of total timing for max power !!! Stock or not factory torque converters are junk !!! I would put a 10 inch in it with about 1000-1500 rpm over factory stall !! Just my simple opinion !!! It's not about big it's about a good functioning working combination !!!

Thank you!! Were getting close, all that is left is the interior. Yeah that is a 8 inch ford rearend, man thats cool that your building a T bucket, ive always wanted to build one myself!!!

Thanks!

Its like a 2000 stall a lil over stock.

It should this motor is a crate GM 4 bolt main!

@@ACDesignsGarage ok thanks

Thank you!!! We're still running the stock crate engine valve springs, you may want to check out comps web site to know for sure!!

Yes

Its 1973 corvette yellow factory color.

Yeah I think so. We just bought a crate gm long block.

There stock crate valve springs, they seem to be doing pretty well.

These are stock valve spring in this engine, its just a gm crate 350. I would probably check with compcams website to double check, but ours work just fine.

I wouldn't use stock valve springs with any cam over about. .450 lift. To much chance of spring binding. Just my opinion.

Heck no lol. Cam is wayyy too big, just wrong for that 283.

@@maynardreed4036 Agree...drives me nuts with guys saying they did so its ok they havent a clue to the damage they are doing SPend tons on parts that are pretty or sound nice but wont spend on a set of springs huh?

I've heard guys say these fit great and there like$ 260.00 in US at jegs. www.jegs.com/i/Hedman/500/69230/10002/-1

Hope this helps!!¡!

@@ACDesignsGarage really am thankful, I just set the order for all the parts like if it was a Christmas list

@@anthonymontoya1577 glad I could help, I love making Christmas list lol, good luck on your C10!!!!

All the Big shops I know buy there engines, I mean I paint, build chassis and do all the rust repair and some interior by my self how much more should I do lol

It should be fine, im fixin to put another in a 1968 327 its goin in my 1965 c10.but thats my opinion lol

No...too big not enough compression

Its the comp mutha thumpr, you want the specs?

@@ACDesignsGarage yes please if you don't mind

@@nofear9867intake .489 lift exhaust .476 lift , 107 lobe separation ,they sound killer, about to put another in my 65 c10

I do!!!!

Isn't that the best of both worlds? A cam that's pleasing to the ear @ idle and is perfectly streetable in a daily driver, well, sign me up!

A lot of internet readers that dont know any better. WHat happened to poring over different mfrs specs, recommendations on compression gears ideal cruise rpm etc. Choosing by lopey vids or a goofy name is stupid.

That's what it's about when it's a toy not drag racing

Yes, it was designed for stock crate engines!

@@ACDesignsGarage thanks

@@phillipfoster1471 your welcome thanks for watching!!!!

@@ACDesignsGarage hey so I just picked up an 89 s10, I’m wanting to do a 350 swap but I have no knowledge on them. Any specific 350 engine code thats better to be built on? I’m aiming for around 350-400hp, what parts would be necessary?

Not sure, they may have the info on there website, Im in NC so we all good here. Thanks for watching!!

No even stock passes California 😂

MOVE to the US

Not in a million years.

Yeah, i just re edited it for people that wanted to just hear the cam

Still sounds good as crap. 👍✅

@@VideoServicesVB thanks!!!!!

@@VideoServicesVB Says you....got something better post up

I agree, lol

Lol atleast its not red

That's all we want, my dad is 74 years old he don't need 400 hp lol

I ran a 351w with the big mutha thumper cam and it made peak power very high it made 415 hp at 6400 rpm, I installed a extreme energy 230/236 roller and it only made 396 at 5700 rpm that cam did make more torque at the low end and was a lot more streetabke but the thumper never disappointed I believe that if I had the smaller thumper cam it would have been more street friendly.

Even those are too big. His compression, heads gear converter are way way off.

@@gordocarbo You are correct Gordo ! I didn't realize it was bone stock !! I need to pay attention better !! The thumper cam specs are all over the place !!! .490 int. - .475 exh. ??? In a stock motor that's a little high and those #s should be reversed !! 107° centerlobe ??? That is way off for the street !!! Should be 114° !!! Then the worst is 235° into - 249° exh. ??? Way too much for the street and you would need a serious converter for those #s !!! But that can makes no sense !!!!! Like a 3500 - 5800 rpm ramp ??? How do you even tune that !!!! Sounds # wise like an NHRA stock eliminator cam for a small block chevy with all that duration and that super tight center !!! Yes , the 284 - 292 - 305 are too much !!!! At least all the centers on those cams are only 110° !! The lift and duration #s are more compatible !!! A 260 - 268 comp cams can hyd would be a much better fit !!! You might be able to get away with a 272° cam too !!! With that thumper cam he'll foul out a lot of plugs and never be happy with the performance of it !!! That's my take !! He needs a performer intake a 600 cm vacuum carb and a cam range of no more then 1500 - 5500 !!!! Please give me your opinion on this ??? I'm 61 y o and ran a number of years bracket racing ! Mostly Atco Raceway started in the mid 12s and finished in the 9.0s. After 20+ years of bracket racing !!!! I miss the racing but not turning the wrenches !!!! Probmissably could still drive but my body could no longer do it !!!! I still love talking about it and miss the mingling with other drivers and track officials !!!! I do value your opinion sir !!!! I always invite constructive criticism !!!!!!

@@gordocarbo According to their profiles they are the biggest cams you can use without using aftermarket parts !!!! If that's true or not I don't know !!!! If it was bone stock on the road I never touched those ! I raced on the track and had no desire to hot rod around the streets !! Way too unsafe and I felt that way even when I was young !!! If I was ever challenged it was my race car and that only saw dragstrips where the cars get tech inspection !!! I saw bodies on the road when I was a kid !!! That was a very convincing thing for me !!!!!

I have a recent video of me installing another cam in a sbc BTW

@@ACDesignsGarage LOL I bet this guy lives in his mom's basement and drives a Honda....and i bet his imaginary engine is badass. 😂. Don't listen to most of these dumbasses on RU-vid man, 99% of them don't know what they are talking about and have never even messed with engines. My dad and I own a machine shop in Mooresville NC and I hear stupid people running their mouth all the time and they have absolutely no idea what they are talking about. You got a sweet ride there brother and it sounds great.

@brad1687 hahaha thanks brother, I hear that stuff all the time. Funny thing is im in Mooresville, NC also

@@ACDesignsGarage that's awesome. I actually live in Sherrills Ford but nobody knows where that is lol

“Amateurs” 😂😂😂 Show us your work please. You know who doesn’t run their mouth on other peoples builds? Professionals.
