I was talking about yanking your 5 cylinder lump and putting in a used late model small block V8....replicating the H3 Alpha
The 5.3L Alpha was the exact same motor/accessories/harness/computers they used in the V8 Trailblazer, Envoy, Rainier, Canyon, Colorado, SSR, and Saab 9-7x. Finding one complete, used, is easy and CHEAP. Plug and play. Then you'd have a Alpha without the cost, and you'd still have the truck you know, like, and trust.
Remember, hot rodding is the American way.
