I'm new to this site and in fact just finished putting my new Holly 4 barrel carb on, 3 1/2 inch straight pipes, gas springs, traction bars, 295 drag radial tires, and crager ss rims on my 71' Mach 1 and an currently looking for a new transmission to seal the deal. I'm looking for a 5 speed automatic with an overdrive, would anybody happen to have any suggestions?
