I would try to answer anything specific that you would want to know. I run 8 3/4 with Sure-Grips in all my street cars. My Cuda is a street car that gets it's share of track time and has a 500" Wedge in it. 1.5 60 foot times are hard on the rear, but I usually get 4 or 5 years of hard use out of a ring and pinion.
If the Dart were going to see much track time, I would have went with a Dana 60 at that torque level. But it has only made 2 passes and I really peddled it then. It is really a show and driver, not a race car.
