Were building a new car for a guy and I'd like to know the stock 12 bolt will be good. He's running a half mile track in a 1975 Buick regal chassis.

My bad !! It has a 10 bolt in it. He can run a 9", but will the 10 bolt compare ?? I heard that the 9" rears are heavier and they rob Horse power. Any thoughts ???

run the 9" while it might be heavier, it is also far safer and superior to the gm units..also a lot easier to change axles!

Do you run the c-clip eliminators? How wide are the tires you're running?
