Re: 4.0 on a 4.2
Get the head, header, intake, all fuel injection stuff, and the computer, from a donor cherokee, (supposedly the MPI is based on a 1994 Cherokee), and have fun. YOu will need to purchase a balancer and pickup from Chrysler? for firing the set-up, the factory set-up has it on the flywheel and I don't believe the flywheel is interchangable between the two.
If you cant find a donor vehicle, you might be better off purchasing the MPI kit.
Just my 2 cents.
