I have a 1970 GTX with an auto trans. The people i get it from were going to make it a 4 speed car, so they changed the rear end to a 4 speed rear(witch is way to low for what i am going to do with the car). My question is what were the stock gears for the auto. I have a beefed 440 with a 727 with a 2200-2800 stall. I was thinking of putting a 3.42 gears with tall 15 in tires. I will be doing mostly street driving.
