I was just at the track and ran a 16.5 with my 88 iroc z with a 305 TBI. I have a open k & n air element, accel 8 mm wires ,the cat has been taken out and replaced with a pipe and i have a cutout to make it open exhaust. What mods can i do to improve this time....i'm lookin to get into the low 15's high 14's. thanx

 

Gears, posi, high stall, exaust, cam... take your pic. You should get low/mid 15s will full exaust and a good tuneup.

I have a set of 373's in the mail they should help out.

 

Do you have a positraction differential already? If you don't, you need to get one. With the lower gears you'll do a massive single tire burnout whenever you try to launch it. You should really like your 3.73's, I love mine.
