Im looking for some ideas as far as cam and pistion combos go. Ive got a 74 440 at 40 over. Factory deck height (for now) 906 heads (not milled) with 1.6 roller rockers, dual coil springs, 2.08 intake valves and 1.80 exhaust W hardened seats and bronze guides. (not flowed, so no numbers yet) Victor intake and 750 DP Carb. forged crank and LY rods. (I may go H beam) MSD distributer (with out vacuum advance) and 6AL box. Rear gear will be low 4.88 ish. Stall converter will be high, 3,500+? This is a race first and street second engine. I would like to be able to run 92 octane. So just how much cam can I throw at this sucker? what is a good comp ratio and pistion to get me right to the edge of pump gas? Im not quite ready to go full roller so keep that in mind. If theres other info needed just say and i will provide it, if I can. Thanks for all your time and advice.
