    Have a 3.7 head ready to go. Company sent wrong head. I needed one for a 3.5, and they wouldn't take it back.

    06 H3 engine swap 3.5 to 5.3

    Has anyone done this engine swap who can tell me what mods have to be done to make this happen. That 3.5 is a pile! If anyone can help it's greatly appreciated, or if anyone knows of a different size V8 that would be better or easier. Thanks everyone.
