I have three slips from saturday 13.86 91mph on a .510 light,was the best run, 14.04 slowest the trans is a TCI but that makes no difference no signs of any motor work other than a EGR replacement and I took the TPI off to clean it out and the EGR port was plugged it was a 1 owner car and ger husband passed so I have no info on this ride

I appreciate your help,my friend has a 94 Z LT1,the day I bought the car we went out and ran them, out of the hole or from a 20 mph punch he can not hang wth me its always me by a couple of feet,I take it to the track and run the **** out of it and get excellent results ,I will do these add ons instead of a supercharger and see what happens,my town consist of mustang cobras,im the only old school T/A and I want to run these dudes in the pavement,thanks again.

I really dont think your car can be stock. 13.8 is just insane for a stock L98. You SHOULD be running 14.4ish at around 96. Maybe you have a cam in there w/ported heads or something.
