You're right 70amcpwr. I just rattled off a quick example. The letter code helps, but some of the letters were reused as well. I just didn't (and am not going to now) go over the entire listing of letters and years to find a "correct" example or two of what I was illustrating. I don't recall what years/sizes do conflict, but there are a few... only a few IF you have a good listing of the letter codes. The engine codes for the VIN doesn't always match the engine build code either. Most do, but there are several exceptions. I don't recall which ones, but do recall that there area few.  I would point out that most people don't have a listing when looking for an engine in a salvage yard, but then they wouldn't have the year listings either. remembering all the codes is tough, but it's not too hard to remember the 2-3 letter codes you might be looking for. For the year code all you need to remember is it started with 1 in 1959 and no 0 was used until 1980, when the code changed to last digit of year. Just looking at the car doesn't help. I've seen early 290s in 1980s Spirits (as well as 390s!). The last 2WD AMC was made in 1983 -- 29 years ago. Engines have been changed around in a lot of them.

Dan, you maybe right about the number being when the engine was made and not the year of the car. My brother bought a 69 AMX 390 new, he was working at the dealer when it was delivered, and in June of 1970 he blew the motor and they put a replacement 390 in it. The valve cover tag starts with a 3, not 2 and it is a 68/69 style motor. It still has the tag on the intake that says it is a replacement motor, it is behind the carb. He had thought about changing it but it is what came with that motor so he left it alone. There have been people that knew what that replacement tag was and told him he should take it off but the motor is the correct replacement and he is the original owner and knows all of the history of car so it is still there.

AZ65440H -- the guy may not have been trying to pass anything off as something it's not -- he may not have known. As I said in the previous post, the last 2WD AMC cars were made 29 years ago.  The last AMC V-8 was made 21 years ago (Jeep Grand Wagoneer 360). Anyone could have changed heads on that engine since the 70s. Most junk yard operators go on the assumption that either 1) the engine is what was originally in the car and/or 2) the buyer knows what he's looking at/for, especially in old iron. The operator can't be expected to know all the codes and casting numbers for all cars, unless maybe it's a specialty yard only covering one make and maybe even just a few models. I don't even remember all the codes! So the buyer has to educate themselves.

Okay, a shameless plug! That's why I wrote "The Red White & Blue Book".  It's a handy digest size spiral bound 66 page book with all the AMC ID number info I could find -- serial/VIN numbers, engine codes, casting numbers, all the door tag decoding data available. It came from variouos sources -- Internet, machinists books, and AMC data books. All was cross checked -- if it wasn't in two different sources it wasn't used. I mean like Internet and an AMC data book, NOT two Internet sites! Just because something is repeated and plastered all over the web doesn't mean it's true -- we've all seen that!! Go to my website if you want one (in my signature). I think it's the best $20 you'll spend if you don't know AMCs -- and even if you do. I made it a small spiral book so it's easy to carry with you to junkyards and swap meets. It's nice having all the numbers right at your finger tips!!

NOTE: I say "all the numbers" but there is one exception -- mid 70s and later trim codes. I haven't got enough info to fully decipher those.  Trim codes are only deciphered through 1974. After that the coding system changed and I don't have enough data books to figure it out, and there is no source I can find saying how the codes were arranged.

That is also the correct 70 or 71 dampener so it sure looks like a 70 or 71 360 with the later model heads installed quite a while ago. 
 
So what I would do with that engine is put new high compression 360 pistons in it and keep the heads that are on it. Have it balanced up, put an 8601 Summit cam (the best cam bang for the buck on the planet for an AMC V-8) and a decent set of lifters other than summit's own (they suck), put roller tip rocker arms on it, keep the Torker which runs great with that cam and put a set of headers on it like these http://www.summitracing.com/parts/HED-98310/ and have a blast with it. 
 
If you want a raise flange 360 crank and 727 core, I have both and we can work something out that won't cost a lot.  I also have used dog leg headers that will fit your American that you can have for very cheap.  I'll be over at the shop tomorrrow afternoon if you want to drop by.
 
I'll be if we ask him real nice, AMC67Rogue will drop by as well.  He is an excellent engine builder and I am sure he can help you out getting the engine redone at a reasonable cost as well.  I have a new set of forged standard bore 360 high compression pistons that are spares and those are about the only thing that would be a little on the pricey side at around $600 with rings and pins, provided of course that your engine will take a standard bore slug.  I can get the rotating assembly balanced for around $180 and even have a new 727 flext plate for a 360 as well but you can buy those from a parts supplier like NAPA for around $65-$70.

The engine shop ran on a calendar year basis, NOT model year. Model years typically started sometime in August (model change over in late July/early august, depending on how extensive the changes were) of the previous year. In other words, 1969 models were built from sometime in August 68 through roughly July of 1969. Engine dates can be as much as two months prior to car build date, though it was usually 30 days or less. So engine dates (years) do not always match model years.

[QUOTE=farna] the guy may not have been trying to pass anything off as something it's not -- he may not have known. [QUOTE/]
 
I know the seller pretty well and plan to pay him a visit this weekend to see if he will make this right.  Trust me, he knows AMC engines and their various configurations from year to year as well as anybody. He is in the business of selling AMC parts and knows better.
 
This was supposed to be a complete running engine and its hard to imagine how that is possible without an attached intake or front cover.  It ain't right and things like this are what really piss off the rest of us who try to actually help out fellow AMCers.

Old post I know but I was trying to figure out an engine I just bought.  3195528 block, no original valve cover so I used the head casting number to determine a late 71 360.  It does have the TF flange on the crank though so either someone used parts to build an engine or AMC used up remaining heads on early 72 engines.  Of course the engine may have been built in late 71 for the 72 model year.
