Im already runnin 13.9 on street tires, stock heads, stock cam, stock bottom end, stock intercooler, stock manifolds, stock transmisson (aod), and no nitrous injection. Since the last run i have bought an art carr spec tranny and art carr converter, slicks, ported exaust manifolds, and prob a few more extras(upgrade intercooler) before the next trip to the track. I think with these mods i should hit 12's what do you guys think? And would that be the first bolt on only sc into the 12's?
