Thanks Buzz, I def don't want to get into something that required an octane boost if I can avoid it. Yes the 11.5:1 comp ratio is a bit high and the cranking pressure of 230psi on some of those combos sound like detonation even on 93 octane. The article I was referring to in my last post was the article that you posted just prior, the 350 that used the old iron (882 I think) heads and a small flat tappet cam. The article you're talking about is from my first post, the 383 using the 190cc trick flow heads. Now I know the e-tecs are superior to the old iron heads but as for the trick flows I really dont know. However, I do like the small port heads for throttle response and low speed torque, which like you say with those heads on a 400ci would be an excellent combo.
