allright i just bought a 91 z28 350 tpi, know nothing about tpi cars i used to have a 87 iroc, but i had a 4 barrel, i got a buddy that likes to run his mouth a lot about his 87 5.0 LX, both cars being stock, with k and n, and exhaust, which should be faster, thanks a lot

 

Is the Mustang a 5spd or a AOD? Do both cars have those mods, or 1 or the other?

I would love to say the Z28, buuuuuut if the Mustang LX is a 5spd and well driven it should win. It's lighter and has similar power. Of course we don't know gearing and condition, but....
