Hey guys I am new to the sight. I have a 1990 ss454 pickup. I am about to drop in a 2004 6.0 motor and had a few questions. I have a z06 cam and springs that a friend gave me and was wondering if it would be worth the swap? The engine is sitting on a stand right now so should be a way easy swap. The engine is a lq4. Also did any of you use the factory engine harness? If so how easy was it to make it work? Any help would be greatly appreciated.

Thanks

Shawn
