Fuel injection For my 77CJ-7 4.2L

[Dan77CJ7]

I'd like to hear any suggestions on what FI system is the best. this will be my next upgrade. I have a Weber 2bbl now and have never got the thing to keep a tune.

Your first consideration should be if there any possibility for future emissions testing. I hear the Mopar kit is the best and most expensive.

I got my 8 with the Mopar MPI already on it (still using the AMC 258 i6 / 4.2l head) and fought pinging for 5+ years. I just put a 4.0 head on and not only has the pinging stopped but I've gained noticeable power in the mid range. I know that here in Ca. its a smog legal swap, but you should talk to a few smog shops about this before doing it, assuming you live where theres testing required.
