Unfortunately, unless you get lucky and score an 8-3/4" rear, you will get an axle that requires a good bit of cash to set up gears. The 8.25" rear is a little easier to find, and generally cheaper, Slants cost money to go fast. I won't try to talk you out of it, hey, I did it, twice in fact. If you are on a real budget, and speed is most important, a junkyard 360 and trans will save you a bunch of money.
