I own a 1980 camaro with a healthy 350, cam, intake, carb, ignition, headers, etc. I am running a 15.5 1/4 mile on street tries with a 2:56 rear gear along with a split diff. I'm swapping it out for a set of 3:90 gears from richmond and an auburn pro series posi. I will be running slicks after I do the swap. What do you think I will run

 

not too sure, but dont expect to get into the 14s if you are consistanly running 15.5s. it will help significantly as more driveline modifications are added, though.however, if you have run faster times, try and reach for the 14s, it is very possible.

 

right now, what are you 60' times and your trap speed and what RPM are you going through at?
