In 1977 I bought a 1974 Gremlin, 304 V-8, 3 spd. It was a true sleeper in 1977, used to routinely take on the early mustang II V-8 and the small V-8 Monzas, pretty close but not quite on the 305's though.
Had a 1972 Jeep Commando with a 304, weird but somewhat rare. Got around great in the snow and off road.
1988 Cherokee 4.0, 5 spd "puke-joe" transmission although I never abused mine and never really had any issues. Again excellent winter vehicle.
I have a soft spot for the old AMC's having owned several and worked on a lot of them when first cutting my teeth in the auto repair biz.
Factory 360 Hornet SC is a rare vehicle and starting to be worth some serious money.
The 304 hornets were much more common and still a lot of fun.
AMC never put a 360 in the Gremlin but they did put the 304 in them.
From there though it is an easy swap to put any of their V-8's in all the way up to the 401.
My wife thinks she wants a restored Gremlin!!! LOL Hey where is the rest of your car?
