i was wanting to get some advice on an amc 360 i dont know much about them and i have a chance to buy one to drop in my jeep but someone told me they aren't a very good engine should i just stick with the AMC 304
No Problem man... Seems to be a lot of conflicting opinions...
Some are saying the 360 has beefy-er parts, larger valves and cylinders etc so more power, others say the larger parts are actually weaker along with the block sidewalls, and the power output is minimal difference... I'm just starting out so have no opinion myself, My AMC 304 is (so far) plenty of power for my wishes, might even be a little wasteful actually as far as fuel mileage etc.
Lots to think about from many angles...
I'd read a whole load of info available, and weigh your personal applications with pros and cons to see what you feel will be best for you.
yeah my 78 had a AMC 304 in it and id run one again but the one i have needs going threw and i can get my hands on a running 360 its only has to run a year next year its getting a built 318 anyway
Mechanically, the AMC 304 , 360, and 401 are identical. The difference is bore, stroke, and valve duration per cam...and in the case of the 401, forged crank, rod, and pistons.
A 360 is no more susceptable to breakdown/failure problems then a AMC 304 . However, because of the larger bore of the 401, they tend to run hotter. The cylinder walls have less material.
I had a AMC 304 when I bought the cj and swapped for a 360. I have been much happier ever since though they do run a tad hotter than the AMC 304 there's a noticeable difference in power IMO, but more so in the torque aspect.
I have an AMC 360 now and am thinking about replacing it with something else. Suposedly the person I bought the truck from rebuilt the motor just 50 thousand miles ago. I get a few leaks here and there and have been trying and trying to seal it up. If I had the chance I would switch to something else. I am not sure if it's a good engine or a bad engine I am just telling you my own experience. Its a 1973 AMC 360 5.9 liter engine.
