Shooting for low to mid-range power, till about 6100rpms. Its a 68 block bored 60 over, block checked good at that bore, I think it comes out to a 311 in my math is correct.

I know these are fairly old cams, but I have them in my garage. Would I see that much better power with a new Comp Cams cam or another OTS cam?

Intake will be a an air gap, if I go carb, or Corbra/GT-40 if I go EFI.

11:1 Comp ratio using 94 oct gas and 75 shot, car will weigh around 3100 with driver, and shorty heads.

Gears will be 3.93s, with IRS if that means anything. Trans is a T5 good for 500hp w/ 2.95 first and .63 5th.

Thanks for any help,
Tony (in England)
