Hello everyone, I'm new to the forum and have a few questions. I have a 2000 rcsb silverado w/ 4.3l v-6. It's paid off now and I'm ready to play. I want to swap in a 6.0l, but I have a few questions. If i get a a complete assembly Engine,harness, front accesories, computer, transmission how hard would it be to swap in? I'm very familiar with engine installations but this is my first computer controlled engine swap. How hard would it be to mate the engine harness to my Dash harness in order to get my gauges to work properly? Also would a 4l60 mate up/hold up to the power of a 6.0? I understand my fuel pump will have to be upgraded and I've already planned to rebuild my rear with a posi. Any info will be appreciated. Thanx.

Marco
