Ok, well I have some cash but not enough for a 8.8 rear, but enough for new gears for my stock 7.5. I was wanting to buy the gear install package from Thunder racing, with 4.10 gears. I have H/C car, not dynoed yet, but should be 430+rwhp, ill post soon, but what im asking is, am I wasting my time? Am I going to just blow the rear in no time, should I just wait and save up for the 8.8?

I think you answered your own question.

You'll be over 430 by a long shot. Forget that 8.8 stuff, get a 12 bolt or a 9 inch. But as long as you don't race it on a super sticky track, the stocker will hold.
