My scrambler came with the 258 stock. Ever since I've owned it, it's had a 360. I screwed up the 360 yesterday, and picked up a 258 out of a '77 cj7 today. Anything I should be cautious of when swapping? The 258 needs a flywheel, bellhousing, clutch, starter, alternator, and probably something else I'm forgetting. How much of this stuff will work off the 360?
