Well I don't really agree that his dyno numbers seem high. I new from the start that he had at least 314rwhp...or was capable of it. You have to understand that his motor is extremely unusual... it would take 22° timing and NOT ping... any other motor would detonate like an Atom bomb.
My buddy will receive more HP than that out of his 302 with slightly ported AFR 165 heads, custom cam (.560 intake lift .565 exhaust lift), Weiland Stealth intake, and a 750 carb. He should easily make 350rwhp with just a N/A 302. Thats about 50hp less than my blown 302!
