I have a 99 RCLB that has a bad 4.3 so I'm wanting to do a V8 swap.

I'm thinking that the 6.0 would be my best bet but I need more info....

What years/vehicles should I be looking for? I know I need a complete engine and harness.

I have a 5spd that I'd like to keep for know but would love to swap to a T-56. Again what years/vehicles should I look for to find the right T-56

I'm going to have to keep it stock for now. Maybe in a couple years I'll be able to Turbo or Supercharge it.

Anything else I might have missed please tell me. Or any sugestons are welcome too...
