me and my dad are taking a 360 out of his truck and putting in a 318. i was wondering if the computer would work for both or should we reprogram it.

Kinda' depends. What year is the truck?

Chrysler Computers cannot be reprogramed.Once the vin is burned in,they are done and the only option is to get a reman which has to be programed with the DRB III.Get a 318 computer intead
