Sounds like maybe a little too much fuel or maybe even too much TB and intake for the stock cam.Gears would be a HUGE help to this combo.Try cutting back a little on the fuel pressure.Ive got a coupe also,and with nothing but a race crank pulley,x pipe w/converters,and no AC or pwr steering with stock gears and it runs 13.84@100 and 60fts in the 1.90s with regular street tires.Maybe you need to work on your launch technique.Whats your mile an hour?

my mile an hour is 97mph.i dont know if im getting to much fuel cause i still have the stock injectors and my fuel presure is at 40psi with vacume on.could it be my throttle body,i already know my intake is to much for my combo but i want to keep it.i would chang the throttle body if i new it would make a diffrence,would it?

well with that mile an hour you are capable of 13's I think your problem is in your 60ft. 2.36 is rather high

just get some slicks and worry about suspension later. If you do anything to the suspension, just get the torque boxes re-welded. Youll hook up fine like that.
