My 91 Z has ran 15.198 @ 96.01 on street tires with the stock 2:73 gears in it which is pretty good for a 305 TPI no cam and no headers. I just put slp headers on the car 3:73 gears and My transmission
has been gone though and has a heavy duty sevro, tv boost valve, Trans-scat valve body kit, and a Breakaway converter all by TCI. I have 26x8.5x15 M/T E.T. Drag slicks on Weld Pro Stars I was wondering what you think the could or might run in the 1/4 mile. All info is apperaciated. Thank you.

 

Well, you'll have a much better 60' thats for sure. The beefed tranny and all that traction you're getting now should let you break into the 14's.
