AMC 360 with a 5.9L casting? Help me identify this please!

I'm losing it here guys! On a college budget, I've managed to save up close to $600 the past 6 months in order to find a decent AMC. I finally finally found one today on craigslist for $100 dollars and literally dove head first on it.

When the guy led me to the back of his garage to the engine, I was in disbelief. It looked spotless. Barely any rust, pretty much fully dressed up, and complete with chrome valve covers, manifolds, and full exhaust. My heart started racing. I played it chill and handed him the cash, no questions asked in fear that the guy would back out at any minute. What I did find strange however was the 5.9L casting on the block, which I had never seen before. I chalked it up to my lack of knowledge and went on my way.

After some quick inspection, the thing looks real clean. I pulled the valve covers and it had super clean rubber gaskets. The oil looks good, no water appears to be in the block. There is no rust or serious damage anywhere that I could find. And it turns over just fine.

The 5.9L casting is bugging me though. The only post I could find on it was form the AMC forum where one user claims those castings to be from 88-91. However, the casting number on the back of the block, 3195528, states that it is a 360 from a 70-84. The heads, with casting 3233344, appear to come from a 79-84. For a second, I wish I had the original valve covers on to simply read the tag!

Anyone have information at all on this, I would really really really appreciate it! Thanks so much in advance, and here are some pics for anyone curious.

Huh??














Block Casting


Head Casting - 3233344

The 360s found in the later Grand Wagoneers had 5.9 cast into the block instead of 360. I don't know at what point they changed it, but I have seen a few late 80s-91 blocks like that.

My 360 has the "5.9" cast in the block. I just considered it to be a newer casting. On a different note, that driver's side exhaust manifold won't work in a CJ, if you didn't know already. It sounds like you got a good buy.

Thanks John. That's good to know. How come though? I feel like I've seen a bunch of 360's with stock manifolds dropped in. How'd you do yours?

You'll need the center dump version for that side to clear the firewall and linkages. It's pretty common and not hard to find. They are the same off of 304's, 360's and 401's. I'm sure someone can post a picture.

Assuming the core is good, you got a great deal.

And, yes, you will need the center dump manifold on the drivers side. It's the bottom one in the pic below. All V8 CJs had them and some AMC muscle cars, as well. Mine came from a AMX Javlin with a 401.

You will also need a set of CJ V8 engine mounts. They are different than the FSJ version.
