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

In this video I let you hear the killer sound of the comp Mutha Thumps cam in my dads 1932 ford Hot Rod. We installed this cam into a stock crate 350 chevy that we got from jegs.com. This cam really woke up this crate motor and sounds awesome. I highly recommend this cam for your cruise in type hot rods!!!! Ill put a link below from my amazon affiliate account. You can purchase the same cam we have in our hot rod in this link . By clicking this link it helps out our channel at NO COST TO you!! Thanks for watching and God Bless Adrian at AC Designs Garage!!!

I've got a 5.7 vortec I stuck the big mutha thumper cam in, i put an 800 cfm edelbrock avs2 and .125 pop-up hammers in order to get any power out of her. Im pulling around 12:1 since i went with the big chamber stock heads. I had to do that in order to really get that cam to shine, i also went with the retrofit hydraulic roller version. Later on i put a fitech throttle body injection kit on, that one is 50 cfm bigger, now I just have to build a transmission that that dinosaur burner won't break. Im still able to run pump gas in her too. I also went with 3" dual exhaust. The cam you have is very close to what the dz302 had as a solid cam, they were usually running dual quad cross ram intakes, i might find out that i will need to bring even more cfm to my dinosaur burner in order to really get everything i can from it, but i still love the idle just as much as not being able to dig around on the stereo when im launching tho, and your whip got a wicked idle, hope you enjoy yours too!!!

[@ACDesignsGarage]

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,

[@gordocarbo]

Big chamber heads doubt you have anywhere near 12:1

[@robertsmith470]

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

[@Exit1Auto]

Welp !!! Thanks for helping me finally pick my cam. I’ll start off by saying I LOVE the channel, I learn so much from you. I have the same stock 350 but with a 2 speed power glide. My car is a 63 impala SS. My question is will I need a stall and if so what size? Thanks for your help.

[@ACDesignsGarage]

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.

[@circletrack7538]

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 !!

[@phantomphoenix6334]

Hey, I just wanted to say i love the sound of the car. It sounds amazing and i love the slight chop it has. Just curious, but what mufflers are you running on it?

[@ACDesignsGarage]

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. kzbin.info/www/bejne/pKTKgoZ4haybntk

[@user-ix9yu8ue8q]

Sounds good..not really sure how your gonna reuse the old lifters. Even if put them in the same holes on another engine..block core shift will not put them exactly in the same position. Cams can be reused but the lifters need to go in the trash..

[@ACDesignsGarage]

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.

[@pythononemo]

Sounds great. Been a few months, is it all working well? Also, I am building a '23 T-Bucket and have an 8" Ford rear going in it. Is the car in this video running 8" Ford? Thanks. Keep up the great videos

[@ACDesignsGarage]

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!!!

[@mikecondoluci53]

sounds good man

[@ACDesignsGarage]

Thank you!!!!!

[@joelseptien5793]

Did you feel a noticeable difference over the stock cam and what degrees of timing did you decide to stay at 12?

[@ACDesignsGarage]

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 !!!

[@Slicer280]

I'm trying to find the right cam for a snotty idle but everything I'm running is a stock 350 from 1972 with a new Edelbrock 2101 intake and 1905 Edelbrock carb I will be running headers too. When you say crate engine from jegs I'b be curious as to the heads I don't want to have an issue where the lift is too high.

[@ACDesignsGarage]

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.

[@circletrack7538]

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 !!!

[@joelseptien5793]

Question. I got the my th350 rebuilt by the previous owner.. how would I know if it has a stall?

[@ACDesignsGarage]

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.

[@goodlifeontheroad]

Awesome job

[@ACDesignsGarage]

Thanks!

[@Conradchristopherson]

Where did you get that color yellow?

[@ACDesignsGarage]

Its 1973 corvette yellow factory color.

[@FrankenVega]

So what's of rpm at idle? With my tunnel ram, it's about 1000.

[@ACDesignsGarage]

Probably around 900 to 1000

[@eduardoperez7797]

Great sound and video on a 350 sbc do i need to change the springs? Thanks for the great video.

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

Thumper cams are feel good cams !! Sounds great at idle but lousy to tune a carb !! Will always run fat or not right !!! A big duration cam with a tight center but lousy driveability !!! Get a good comp cam that's ground with the right ramp !! A 284 - 292 even a 305 !!! Those are good power making hydraulic camshaft for your money !!

[@gordocarbo]

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

[@circletrack7538]

@@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 !!!!
