    Default 2004 chevy 4.3 to v8 engine swap help

    i was thinking about swaping my 4.3 engine in my 2004 chevy single cab for a v8 of some kind... or would it be easier to just drop in some engine mods like a cam some headers electric fans and stuff would that be better and cheaper then the engine swap...i was wondering if it would just be cheaper to not worry about this and get a new truck with a v8 or about the same money to just go ahead and do the swap... i am not too sure if the wiring harnesses of the 4.3 that are in my truck now would match up to the v8 harness... any help is appreciated

    another member on here did swap his 4.3 to a 350. He made a great write up of the project. Here's the link

    you do know how 6.0 liter looks like right?

    and how you could tell if its a 6.0?



    very confusing if you dont know.
