I have heard people talking about using a 4.0L head and f.i. components to turn their 4.2L to F.I. and wondering if anyone has seen a write up or has done this mod. Tried searching but didnt come up with what I wanted.

Well you suck at searching. might need to try HERE TOO (http://www.google.com) .

Its basicly the same as swaping a whole 4.0 wiring wise. Just use the 4.0 top end and your bottom end.

*Note on your "bottom end" You may need to remove your head befor inserting the 4.0 head. :flipoff2:
