Help with my combo.

Post  njstang87 on April 12th 2012, 1:50 pm

Hey guys I am putting together a big block fox together. It is a 93 hatchback. The transmission is a stock C6 for now. I have the hooker swap headers. The engine is a 460 that is .60 over. It has stock DOVE heads with head studs. It has stud mounted roller rockers. I am wanting to run a torker II to get it under the stock hood. My question is about the camshaft. My dad is letting me use one that has very low run time out of his pulling truck. Here are the specs on it


Intake / Exhaust
RPM Range:3500-6500 Valve Lash: .03 / .03
Valve Timing: .02 Duration: 294 / 304
L obe Separation: 108 Duration @ .050" Lift: 256 / 266
Intake Centerline: 108 Valve Lift: .589 / .615
Lobe Lift: .343 / .358
Valve Timing @ 0.02 Lift:

Exhaust
Closes 44
ATDC
Opens 80
BBDC
108

I have a 750 carb I am probably going to use. If I have left out any information let me know. Thanks

That cam works great in a 466 with a little compression.

Get a bigger carb, make sure you have a good loose convertor.

Well I am not sure on the compression but his pulling truck had 11.5:1. With doves on my combo will the cam be alright? How loose on the converter?

4500-5000

11.5 should be ok, the more the better.

3.73's with a C6

A 1050, Victor and some correct porting will go a very long way

Last time I ran that one it was a 466 @ 13:1+, blended CJ iron heads, a glide, 4800 conv and 3.89's on a 10" slick, ran consistant 10.10's with a victor and a 1050

Sorry I wasn't clear. The engine the cam came out of had 11.5:1. I am running stock DOVE heads with a stock block except it's .60 over. I don't know the compression but assume it is in the 10's? Will that still be ok? Basically I am seeing if I should order a new cam if this one won't work with my combo. Thank you for your responses.

Get a smaller one, you'll only be in the 9-9.5:1 range, it will be a dog.

The camshaft has too much duration; the lift is about right if the heads have been modified to accept it. It is less than a couple hundred dollars to get the right one ground for that engine.

Assuming 72 cc, flat top piston, .000 deck, .041 gasket you would have just about 12-1 compression. That cam should work pretty good although you didn't state convertor stall, gear ratio, tire type and size, and weight of car.

If you have to run the Torker II I would use a 950 HP carb. A Victor and Dominator would be my first choice.

I know that camshaft. I was a long time ago, but it's a Comp that for sure. It will work well; I ran it in a 4000 lbs. '73 Torino with a stone stock '71 460 w/a Offy intake, 800 cfm holley. I was even able to get by with stamped steel cj rockers with poly locks. Best et I think was 11.79, with a C6. With a TH400 11.48.

Maybe some one should ask him if it's a DD or a race car. Before an answer is given.

Thank you everyone for your input. I have dropped the K-member 1.5". I actually have a victor sitting on the shelf. From everything I have read it won't fit under a stock hood and air cleaner. I emailed Comp and they said they recommend a custom grind.

The car will be a street/strip machine. Basically a toy.

Honestly Guys I am not sure what converter to run or gears. Any input would be appreciated.
