That Jeep 4.0 was one of the best motors ever built. Also, it's earlier versions the 232 and 258 in the American Motors Cars. I bought my Son Don a '74 Hornet to drive while we were building his Olds convertible for him, he drove it for a couple of years, then I got it back and drove it for about 4 years, and we still see it running around town. It was good on gas and you couldn't kill it.
