Hi, I was wondering how difficult it would be to swap a 4.3L for something with a little more guts. I have a 1992 K1500 and I need to know what componets from the 4.3L I could use. Obviously I would need a new intake manifold, headers, ECM, and a couple other things, but could I use the same Throttle Body and wiring with an ECM from a 5.7L that is also a 1992. What sensors and stuff would I need to change? I wanted to get a crate engine and not go and pull one from a donor that already needs to be rebuilt. This would be my first engine swap and I was really hoping it would go smooth and give the extra power my truck is craving.
