Has anybody put a Chevy 350 in a TJ? How did you go about making it run. Trying to help my brother figure out the rat nest of wire the guys he bought his TJ 350 from.
The jeep ran fine for about a year before it started to run like it was not mixing air and fuel correctly. We have gotten codes for O2 sensors and for missfire. But never got the same codes twice. I suggested to rewire the whole thing but dont know where to start as far as what parts to get.

I have not but there are many who have.
Do you know where the 350 came from? Is it naturally aspirated with distributor or fuel injected.?

I can't really help, but I'd love to see some photos.

It is fuel injected. He was told the donor vehicle was a 98 1500
Terry I will take some pics tomorrow.
