LOL, it's cool. But I am only installing a 4.0 not a 4.6. But They are pretty much the same, and there are some problems I have run into that I am in the middle of trying to sort out. But from what I have done Ithink the easiest way to go is to make the 4.0/4.6 more like the 3.9, and by that I mean changing the front cover on the engine so you can run with a distributer and a 14CUX ECU. If you want to convert to a GEMs electronic ignition there is 1 big thing I learned, for the GEMs system you need a cam shaft positioning sensor. The sensor has pickups on the flywheel, but if you are like me you have to change the flywheel for the manual trannsmision as most 4.0/4.6s came with an automatic. Well the manual flywheels son't have the pickups. I learned this the hard way. I'll come up with a better list of what is needed and what work is involved when I am done.
