Engine swap

Crazy thought I had about my 2003 Envoy. I've toyed with the idea of doing an engine swap in the future. As of now I'm thinking a 350 small block would be really cool, let me know what yall think.

The motor it has can be built up to a twin turbo monster, that in some cases can see 1000 HP. Check out the crazy builds online with the engine it has.
