is there such a thing as a 8 1/4?

8 1/4s are very good rear ends, most guys overlook them, but they were the replacement for the 8 3/4 when that went away. If one is built properly, you can put a good amount of power through them, Ive heard between 500-600 hp. I am sticking one under my 73 Swinger, it has a Trac-Loc unit installed and should be good for what Im doing with the car. If I end up building the car for any more than Im doing now, Ill go with a Dana rear end.
