RE: Changing from a 318 to a 360?
I did the swap last year.
Use your current wiring harness, but you will need a PCM for a 360.
Also, you need a 360 harmonic balancer and a 360 flexplate. The ones from a 318 WILL NOT WORK. The 360 is an externally balanced engine and the harmonic balancer and flexplate have the weights that do this. The 318 is an internally balanced engine so that harmonic balancer and flexplate are weightless.
Use all of your current bolt-ons and everything will work correctly.
