Yes, there are several ways to put together a GM rear end. If I knew the the correct ratio, it would be the best way. That's the trouble. Many cars are geared too high and simply won't pull it or too low and can't achieve the top end speed. With a GM rear, it's a pain in the rear (no pun intended) to change. Unless you know the Cd, rolling resistance and RWH horsepower, there's no way to know the best gear ratio. That's why I decided to initially use the ford 9. That's also the reason I'm try to figure out how to make it more efficient. It does take more power to turn but it's easy to change ratios. Because I'm just a Po-boy, it has to be trial and error. There just ain't no way to get there from here!
