Hello all I have just purchased a wagoneer and this one is actually my second one. I am trying to find out just how reliable the amc 360 is. I have read many post and some members say that the 360 is not reliable at all and they are afraid to let thier sons, mothers, wives and daughters drive them. other members say that the rigs hold up forever. What is the verdict? are they reliable or not? mine seems to operate fine but that could be due to the fact that I replaced almost everything and rebuilt the engine. My brother is considering buying a rig but we dont want to get another if its going to fall apart on us in two days. If the rigs are not reliable what do I do to get it into good reliable shape? (some of you have said that the emmissions equipment is the cause of the unreliability. if this is true how can I remove or bypass some of the emissions stuff to make it more reliable?
reliable 360 engine?

The 360 engine was used in Jeeps for over 20 years, thousands were produced. No inherently un-reliable engine could have a record such as the AMC 360. They are still successfully used today in every performance category from off-roading to drag racing. They are good engines.

It all depends on how well it's been maintained. The 73 J4000 w/360 I sold to a friend is still running fine and it's got over 175,000 on the clock. It's never been rebuilt but does have a new timing chain. Do a compression check on one you intend to buy. If it reads good then it should run quite awhile but buying any 20+ year old used car Jeep or otherwise is a crap shoot at best.joe

As with the majority of engines, it's not the internals that will strand you in the boonies as much as the accessories and such. Things like the alternator, ignition, fuel supply system, carburetor. Not very often the engine will throw a rod or bust a crank without letting you know plenty in advance that there's a problem coming.
So, with that in mind, I'd say the Wag is as reliable or unreliable as the maintenance that is done on it. If it's regularly serviced and kept in good tune, with attention being paid to all the stuff that wears and ages, it's as good as anything. But, if the only time the hood gets opened is when it's obvious that something has gone wrong, then it's gonna let you down.
My $.02.

The 360 AMC is no better or worse than any other
engine from the big three. Take care of them and
they will take care of you. Any swap engine even
done by a pro will likely be more unreliable than
the 360, not because of bad work but because Jeep
did the engineering and had many 1000's of Jeeps
to work out any bugs and details.
Chevy swaps are popular and can be a good chioce
but not for reliabily, or that they are better engines
what Chev does have is a vast sea of aftermarket
support and many no adapter tranny choices.
For the best $/mile the AMC will beat a swap in
hands down. Last a long time if kept in tune and
oil changed.

My 85 may be getting retired to a parts truck soon, but not because of lack of reliability of the Ol' 360! 286,000 on that engine, and it still runs just as good as the one in my 84 with 90,000. Doesnt even burn oil much(a little until warmed up). It's body however isnt so lucky. Wisconsin winters have taken a large toll with the cancer factor.Rob Milton<br />84 Grand Wagoneer- The project<br /> AMC 360, all stock for now<br />85 Grand Wagoneer- The rust bucket<br /> Currently driven by my wife- was purchased with the \'84 as a parts rig

Any motor will be as good as you want it to be. Please bear in mind alot of these rigs have been beat to near death.
More so with the J trucks. My rig has the 360 with God only knows how many miles. When I purchased the truck 9 months ago, it had not been taken care of. At all.
She still fired up. The motor now has received some much needed attention. Compression is excellent and as far as engines go, I couldn't be happier.
Please remind me of this, when she decides to puke a rod. [img]smile.gif[/img]

I've got 150k on mine and it runs great. I've never been afraid to take it anywhere and I've taken it to some pretty remote areas with nobody in sight for miles. I do maintain it well too though. Do regular maintenance and look for things that might be failing and replace them before they do and you'll be set assuming the motor was in good shape when you got it.
