I have a 95 yj 4.0 ax15, wanting to go v8 I have a donor motor and tranny ( 95 tbi 350 and a 4L60E) I'm mechanically inclined but scared of the wiring. Should I stick with the electronic setup or convert to Carb and find a 700r
it depends do you have the full chevy truck sittin there you can pillage for parts like the harness and ecu? and see how it all goes together and id get the 700r4 behind the TBI 350 in my thought prosess that might be flawed
There's a line between adventure and stupidity.

With the amount of money you'll spend sourcing a new tranny and converting to carb it shoud NOT even be an option, in the end you'll have a carburated engine that will most likely give you runability problems on the trail. IMO A fuel injected engine with electronic ignition is much more reliable.
Wiring isn't to bad on that swap you need to retain the Chevy fuse block but take out everything you don't need (lights radio wipes etc) then pull the stuff you will need to keep in the jeep from the jeep fuse box and swap it over to the Chevy box one relay at a time testing each one as you go. This will eliminate the jeeps original under hood fuse block and tie the Chevy in cleanly while giving power to everything you need. As stated above do yourself a favor ditch the 4l60 and go 700r4 trust me you won't be happy with the electronic.
Just my opinion on the 4l60 but I went through 4 level 10 4l60e's in my tahoe had TCI trans controller, paddle shift 600 HP and every upgrade available internally. It didn't like leaving from a dead stop over 2500 rpm. Just realize the trans in a vortec setup needs to be receiving every signal correctly or it will melt down. If changing to another trans is not an option use the trans go T74173E $275 full manual valve with no electronics. Had this kit in my lt1 Ford ranger worked great.
