JEEP 4.0L engine to GM PCM?

[THEFERMANATOR]

You guys are having too much fun!

I'm doing a similar GM ECM to a 4.0L engine but plan on using a 427 ECM as I am familiar with the earlier OBD 1 stuff. Plans are using my 258 bottom end with a 4.0L head and the newer 2001 tuned port intake. Originally thought of removing the throttle body and machining a GM throttle body. But recently looking into using the Jeep throttle body, IAC, TPS, IAT and possibly the MAP as they are already there but don't know yet if the GM ECM is capable. So I will be following along here. Good luck with your swap!

I would highly reccomend going with a 4.5L budget stroker over a 258. It will be a very worthwhile upgrade in the end for power. I've done one with a carb and it is IMPRESSIVE! I put less than a grand into it as I had alot of spare parts, but it will burn the tires in 4th gear with 32's on it. U-joints and driveshafts though have a short lifespan.
