A little background. I bought a CJ8 earlier this year. It is a nicely optioned Laredo model. It has a rebuilt engine and transmission. The engine runs rough. I am on the fence what to do with the drivetrain. Do I keep it relatively stock or swap in a late model 5.3L and 4L60E? I know how good the GM parts are, I have done many swaps. I would like to hear feedback from folks that have used off the shelf fuel injection kits (Howell, Holley, Mopar). Thank you!
Input needed: Fuel inject stock 258 or 5.3L swap

The carb is bad. So I would have to rebuild or replace it. I rather not throw more money at the carb.
Yep. I've done a few dozen V8 swaps. I would use a GM auto transmission and a set of Dana 44 axles I already have.
I'm older, so power isn't my motivation. Reliability and drivability are what I am going for. I have a LJ that is my offroad jeep. The CJ8 is more for fun around town and mild trails.

I looked over their website recently and the kit they now offer looked different than the Mopar. To me looked like a repackaged/customized sniper EFI. I talked with them about a year ago, the problem with the Mopar kit was non-avability of the proper computer and the discontinuation of some of the connectors for the wiring.
The new kit may be better than their prior Mopar kit, hopefully so.

20 gallon poly tank vs 15 gallon steel tank. The Holley drop in is for the steel tank. I don’t think they have one for the poly tank.
Either way, this keeps all new wiring under hood. Also, my boat has used a similar “fuel control cell” as pleasure craft marine calls it. Has worked great for 18 years. Figured if it was good enough for a boat, should work well on a Jeep. Also keeps me from dealing with an “out of tank” fuel pump.

I have the MPI from years ago and it runs great after working out a few bugs. Yeah, they stopped making the specific computer, but the 4.0L computer works with one or two tweaks to keep the engine light off. It runs really well and reliably. I don't need more power unless I wanted to drive 70mph (which was never part of the original design!) or break stuff.
