8 1/4 vs. 8 3/4

j par said

it is things like this that makes me feel I have a little time before I need to run out and buy a dana. But I'll be keeping an eye out for the right deal in the meantime. Again I'm hoping the 8 1/4 will last long enough to see if 355's are the best gearing?

I don't think that was a real good example of a 8 1/4 holding up under power....he said it was a mild 318, so probably 180hp ish. Also, 4 speed + power + 8 1/4 + sticky tires = broken parts....either the 4 speed will break, or the rear will break.....and yes, I know, I must be some sort of mathematical genius to come up with that formula...:D.

Seriously though, if you are planning on racing quite a bit, unless you are a die hard 4 speed guy (and very skilled) I would seriously consider switching to either a 727 or a 904. They are easier on the drive train, and WAY more consistent...and consistency wins races. Just food for thought.
