No reprogramming, Keep in mind no road test yet.
For the cam sensor I had to grind down that area to the thickness of the location on the 3.5L and drill and tap for the hold down bolt and then used a whole saw for the sensor whole ( I know redneck but all I had close to the same size) Backed a bunch of grease behind so no shavings would get in the motor.

OMG!!!! The Beast here - is there an emoji for pulling out what little hair I have left?!?!?!? I like the idea of swapping my 3.5 for a 3.7 V-6. How hard is this going to be??? What all will I need aside from a completely new exhaust system?

Nice job on resurrecting a FIVE YEAR OLD Thread.... and what scoreh3 said, a 3.7L is NOT a V6.......... READ: Old Threads/'Necro-Bumping'
