I have a 4.0 engine I just want the head and exhaust from, if your interested in the fuel injection setup maybe we can work something out. I have read about the 4.0 head onto a 4.2. Eventually will try it, right now I just upgraded to a motorcraft carb kit and working on either a HEI or TFI ign. I think I will probably leave it at that.
drop me a pm if you think this might work for you

good luck
