Hello all needing a little input on my 90 rcsb Silverado. I've got a chance to buy an 04 Joe Gibbs supercharged engine and tranny complete with ecm and harness. Suppose to make like 420hp I was told. My question is, has anyone done this swap before in our trucks and what all is involved. Thanks for any help with this.
