do you think if i run race fuel it would run any better and what octane should i use??...thanks

With all of the alum you have it should stay pretty
cool and if its tuned correctly for the 93 it shouldnt
be a problem

each to their own, but if that was my engine with that compression & cam, i'd run 103-105 octane. our fuel might have a different rating but even so i'd take a jug of higher rated gas & try it out. you'd have to bump up the timing a bit but if it meant going faster i'd try anything.

I'd put a wideband on it and see if that fuel pump was running out of juice well before the traps. You're feeding a lot of carb there.

I agree. Detonation cannot always be detected until your rod bearings drop out of the saddles. I understand what Mike is saying about the aluminum but with 11.5-1 I would use some amount of race gas-just to be safe.
