what should i run? 94 z28- auto
mods:fresh engine with ahot cam, roller rockers, lt4 valve springs, lt4 injectors, lt headers, off road y pipe, magnaflow exhaust, tuned computer with shift points changed,a/c delete,2200 stall converter, shift kit, and vette wheels with 275/40/18 in the rear and 245/40/17 in the front

 

i wouldn't expect too much. low 13's high 12's

 

With 3:73's gears, a little more stall (yank ss 3600) you should hit 12.5x's easy.

 

well yeah...i was going with what he already has. a good stall will cut .5 off his quarter time alone

 

also depends on the shift points exactly, and by fresh do you mean brand spankin new ?

 

i guess i took it to mean stock rebuild
