Engine
Engine wiring harness
Transmission
ECM / PCM
Gas Pedal
Air Intake if your going to use the stock one
Might as well keep the fuse block under the hood
Overflow tank
Mechanical fan if your going to run that

On my swap I'm trying to make it look 100% stock under the hood. Other people have done custom air intakes and electric fans.

Also is the truck going to be 4wd or 2wd in the end?

Good luck,
Nick
