Hi guys,
I'm not ready yet but when the engine does go and since the body and suspension is in great condition, does anyone have any experience or know if you can replace the 4.0 290HP with the 4.2 400HP? I would assume I'd have to change the trans and the ECU? Just a thought for now. Thanks in advance.

 

Search the forum well...I'm pretty sure this subject has been covered.

Good luck (when you decide to go for it).

 

Putting a 4.2 in is easy, putting a supercharged engine in not so simple
