Toyota offers at least a couple of ratios- - - -depending on whether the car has a turbo or not. I believe one of them is a 4.30:1. There's also a 3.73. I'll be using a Supra rearend behind a Cadillac 390 engine and a turbo 350 or 400 trans in an Excalibur roadster I'm building. Maybe a 4L60 overdrive if I can find a stand alone control box. I have all three transmissions on hand.
