I had a '75 CJ-5 for several years. It was great with the stock 304 and three-speed. Until I removed those & added too much horsepower for the stock drivetrain and suspension to handle. I pretty much twisted everything, including the frame, and passed it off to someone else for further modifications. But it wheelied great with a welded rear end and bald 36x14.50 Swampers. Damn I miss that Jeep. It got me more tail than any rig I've owned. Including my wife. I picked her up in it for our first date. I had the top off, in February, on the Tacoma waterfront.
