I have a small block 400 with 202 heads and a Comp Cams 268H 454 lift 268 duration and a 671 blower with two 500cfm carbs, I'm looking for someone that might have a HP calculator to give me some close HP numbers.
Thanks

Look for someone with a dynomometer, anything else would be a meaningless guess.
A dyno will be the best, because it's exact. Those hp calculators are useful also,they will get you close.

i'm guessing on way too much stuff:HMMM:
exactly what type of heads do you have? i guessed wedge pocket porting,big valves
compression ratio, i guessed at 8.3:1
