A few years back I built this 79 C-10, installed a 327 with a Turbo 350. The truck was slow to launch with the factory 3.07 open rear end. So I have decided to turn it up with a series of modifications.
1. Build a 5.13 geared locked 12 bolt with 5 on 3/4 Axel pattern
2. 5 inch aluminum drive shaft
3. Re drill front brake rotors for 5 on 3/4 pattern
4. Lightweight wheels and tires
I started with the rear end build, some pictures. I guess there won't be pictures, files too big..........
