the computer of the engine going into the vehicle being upgraded. all wire harnesses too. be sure to make the fuel pipes fit. those are just some of the things to watch for. research online too on youtube.

Engine, harness, pcm, fuel pump, the ability to custom wire the vortec harness to your truck for gauges and the ability to start and what not. It's more cost effective to sell your truck and buy a 96+ with the v6 already there
