16 something. The only way you'll know for sure is to take it to a track.

I'm I correct in thinking there were no 305 AUTO GTA's. The GTA was only ever given a 305 if ordered as a manual tranny?

Hell My car goes 14.7s & its totally stock. I am pretty sure you car can do something around the go around of low 15s with your mods on your car even if its just headers

16s w/305 TPI auto??? It's got 215hp and like 275#s so I would say low 15s, like 15.4-15.2. It's not slow, you just got a small cam...

oh cool, i am from nf canada, and we only have one 1/4 mile track in the province at its a 3 hour drive away over a rough highway so i don't get out often. also if it makes any differance my car had a 2.77 rear end stock but that has been changed to a 3.27 with posi, so maybe that could make a differance too?
