You've spent this much money on the motor now it's time to consider rear-ends. Don't waste your money upgrading the 8.8. You'll spend more in the long run. So what if it adds a little weight..you can still take weight out of the car in other areas. Get a good 9" rear with Moser 31 spline axles and c-clip eliminators. get the 5/8 studs for the rearend. Throw in some 3.73's and go at it. You might want to look at coil over shocks..say about a 50/50 in the rear.
