6cyl that needs rebuilt. The Jeep is a rare color combo so I wasn't sure if I should put the original motor rebuilt.

RIP Mike, we'll all miss you
IMO, do what you want with the rig. Its yours, and you want to make it your own. Very few CJ owners get what they have invested in a Jeep back out of it when they sell it.
Personally, I'd probably keep the 6 in it, just for simplicity's sake. Rebuild it if you have to, install another one if you must. CJ buyers don't normally look for matching numbers like muscle car buyers do.

- 1982 Jeep CJ-7 350 Chevy V-8, SM-465 4-speed trans, Dana 300 Twin Stick, Narrowed and locked GM 14 bolt rear, Narrowed and locked Dana 44 front, 38.5" Super Swampers. Fiberglass tub. 6 point roll cage.
In my opinion, there is nothing quite like a healthy v-8 in a CJ

- 1986 cj7 258, t-176 4-speed, d-300, moser one piece axle in back in amc 20,G2 4.10 gears front and back, detroit truetac front and back,G2 4340 chromoly front axles in a d-30, 4" rough country lift, 33" tires
In my opinion I have a AMC 258 i6 / 4.2l and theres not to much diff. between a 258 and AMC 304 . In my opinion the 258 if better! Just my 2 cents. If looking for more horses go to 360, 401. But like said before its yours. And what you want to do with it. Street-off road or a off road killer trailer queen
Just joking don't want to upset anybody

There is nothing wrong with the AMC 258 i6 / 4.2l and if you decide to keep it and do a decent build you won't regret it. There are a lot of good things to be said about which ever way you decide to go.
the 4.2 is a long mileage dependable machine and there are a lot of tweaks and mods to make it as good as anything else you are going to find on the trail. IMHO
It's not all about the engine, the rest of the drive line is as important if not more. All the horses in the world won't run if you can't keep in on the ground.
Think about the package for a while. weight,torque,ratios,tire size. There are just all kinds of places to spend money on this machine, make sure you get the most bang for your buck.
I love my 258, it has ALWAYS made it home.

If your doing the restoration as a collector vehicle, rebuild the original.
If you want a daily driver it may be cost effective to throw in a road ready AMC 258 i6 / 4.2l .
If you to turn it into a noise maker hot rod type then go with the v-8 but like others have pointed out, the are other considerations.
