how to beef up the 8 inch differential?
I finally got my 69 mustang to hook, but then after 1 pass I grenade'd my rear end when I launched. Does anyone have any tips for strengthening the 8 inch? Or will I need to upgrade to a 9? This car is my daily driver but it will see a bit of track time.
The car is the factory weight, .040 over 302 never dyno'd but I'm guessing around 350 horse, it's a 4 speed car, 26x10 street tires, traction bars, and a mini spool with 3.55 gears. It runs 8.20's in the 1/8th.
