Hey all I have a 1998 gmc c1500 with the 350 5.7, I am currently doing an 4-6 belltech lowering kit and down the road im swapping my motor and planning on making around 400-450 hp to the wheels. I was just wondering if anyone had any suggestions on upgrading the rear end I have an gu6 10 bolt at the moment. I wanted to either build mine or do an axel swap so I was going to see if anyone on here built theirs or had experience swapping their rear end. Thank you anyways.
