Hello all. I picked up a s197 engine sign 50,000 miles on it for 1000$, and decided I'm going to swap the engine out of my 97 GT. Everything I've found online says most people are using the existing wiring and ecu, and locking the variable valve timing. My question is, why do they do this? I would imagine you'd want to keep the VVT, and leave the wiring and ecu that's standard on the s197 engine intact when you do the swap. Does anyone have any advice before my brother and I get into this project? Or a forum that details doing a similar engine swap? If this is posted else where forgive me, like I said my search for information didn't show an article involving keep the s197 engine and wiring harness intact. Thanks in advance for responses and advice !

Yes there is a 3V swap harness from Ford Performance available, it is expected 5/19/17. You just need to change to a return style fuel system
