Thread: Procomp aluminum heads/ kmj performance heads

I have noproblem running a roller cam but help me out a little. Here is what I am building. 454 .030 over with .210 dome speed pro pistions which will give 9.7 to 1 compression. I will be using the stock heads with stgainless valves. I would like to run full roller rockers. I will use the edlbrock performer or performer rpm intake and a 750 carb. mallory ignition. It will be infront of a th350 and 3.08 gear to start. At some point I would like to upgrade the trans to a 700r4 and the gear to a 3.73. This will be in a 70 chevy truck with an 8 foot bed. If you have some good choices please let me know.

Thanks, Wes

Do you want to run with a stock rated torque converter or are you thinkig about a higher-than-stock converter?
About how much does the truck weigh?

used many hyd rollers over the years let me know if you want to run a stock stall and if you going to be pulling any thing with the truck if so less stall to no stall over stock and i tell you what i used in the past builds

I am not pulling anything. I was planning a 1700 to 2100 stall.

Doesn't say anything about torque converters or stall rates.

Very tame cam. For vehicle weight I guessed 3500 lbs.
If you like to check things out, go to the compcams site. They have a program where you enter engine specifics & vehicle weight, & you can flip thru the recommendations. They have full kits down to just cams.

NOT recomending this particular cam, just giving an idea, & a site if you're interested in looking at some offerings.
Hope there was something helpful!!
