[QUOTE="Walt Jaquith, post: 427876, member: 18654"] The Jeep inline sixes really only have one thing to recommend them: They're inline sixes. It's a naturally balanced configuration that's hard to screw up, and so straight six engines tend to be durable, and Jeep's versions are no exception. In the minus column they're way too heavy, not particularly efficient and have badly outdated fuel and ignition systems. Just check out how many posts you see on all forums pleading for help with mysterious no-start troubles to see the problem. If you're going to swap a different engine in, the obvious choice is a GM small block because of the huge support that platform enjoys across the board. You can go anywhere from an ignition points and manual choke setup from the early 70s to a modern fuel injected drive-by-wire with no distributor that will always run perfectly under any conditions. Almost any of them will give you more power and economy than the Jeep 6, and most of them will weigh less. But hey, if Chevy isn't your thing, once you get the stock engine out, just about anything will fit under a YJs hood. 3 cylinder Yanmar marine diesel? Heck, someone's probably done it. [/QUOTE]
