258 or 304 is personal preference.

I had a 258 in my last CJ that I built with Clifford Performance products (390 Holley 4-BBL on a 4-BBL Clifford Water Heated Aluminum Intake, Dual Exhaust Clifford Headers mated to a 2 1/2" custom exhaust run all the way out the back, and Mild Duration Cam). It was a great performer and great daily driver, and when I went to a gas station, people used to ask me if it was a 350 in there, and they S**T when I said it was an inline 6 It was fun and different engine that many people don't see everyday, so it gets attention.

My next Jeep listed below in my signature has a 360, and I have yet to drive it around to experience it. My next frame-up build will be getting a 401.

So, basically, do whatever you feel like and whatever you think will be most fun. a 350 swap will be more costly due to the adapters you will need, etc., and you can get plenty of performance out of a 304, if you decide to go V8.

I have a 1974 CJ5 w/ a stock 258 and I just filled up and got 17 miles to the gallon and thats w/ points and a carter one barrell carb! The only plans I have for it "may" be a switch to electronic ignition and a weber carb. I think the 258 has plenty of torque and I would rather put the money into the x fer case, lockers, and other drivetrain mods. If you want to go fast buy a muscle car!
