The 91 GT is my old car. Sold it to a real good friend. Still tuning the Megasquirt but 5 speed is coming out soon for a built AOD with 9.5 Edge converter. It has 3.27 gears and stock motor except 1.7 rockers and an '88 speed density cam. Went 14 flat on 89 octane. 6 psi with base tune and 18 timing went 12.5s The Challenger is old friend and former GN, T Type, and TTA owner.
