Tony,

I think a mid 3 series gear, a little more stall in the converter, a newer and hotter camshaft, an 850 CFM carburetor and a good flowing exhaust (read headers and dual exhaust) would at least put you in the mid to low 13s. Going any faster will require more machining, more compression, after-market rockers for cams over .500" lift, a solid bottom end, and some porting on the heads.
