Had mine up to 140MPH (GPS)after the LT1 install and O/D trans...had plenty left but backed out...HMMM just started thinking 140MPH + 29 yr old car..I thought it was good enough..Although having Z rated 275/40/17's all around made it feel stable and it is a 4 wheel disc brake car...didnt feel like chancing anymore...but it was cool

I topped out at around 105(also GPS) with my 80 T/A on the highway with around.. 450 lbs of weight in the car.  This was also with a closed shaker, leaking stock exhaust, 3.08s, a warmed over 301, and no front air dam.
