Cool. I was just searching and reading. I swear I've searched before and not pulled much info, but I found some stuff this time. Faintly do I remember Banchetta's dyno that shows stock, +4 and like +7 or something, and his dyno showed +4 making the best power for stock and ported machines, up to +4 mil. I'll just leave it the hell alone. His dyno sheets have been pulled, so you can't see them anymore.
Mostly, I was just wondering what the fellas running the more advanced motors knew that I didn't, you know, don't want to miss out on free hp, like that really exists. I know that the ignition curve falls off quite a bit at higher rpms, and maybe this is why the draggers like it so high, because they're in the higher rpms mostly and that allows a more advanced timing in that higher rpm area. Who knows.
Later.
