Have a complete Holley 2D system for the jeep 4.2L. Was gonna freshen up my 4.2l and add injection, but once I got it out a V8 is now making its way in :D (funny how that works) I never had it running myself, although the previous owner claimed it works. It appears to be complete including install instructions, I'll post some pics later tonight. asking $480 OBO, will ship
