6.5 military surplus engine

Unless its a 506 AMG block, thats the one to have. Look for two diamonds under the intake cast in the center of the valley of the block, also 506 will be cast in dots on each side of the valley. The 506 is the best or worst block, just depends who built it.

The turbo HMMWV's use van heads, so you really dont want one of them unless swapping heads. Plus most turbo engines were in armored HMMWV's, they were worked alot harder(about twice the weight).

Why would the military be unloading NEW engines? Past the best-if-used-by date? Caveat emptor!

Well some AMG's are not so new now, they been building them for around eight years now. I was just pointing out that all 506 were not bad, to inspect closely you might get lucky.

Most HMMWV pull out engines will be 6.2's, some will be GM 6.5's and a few AMG's will find there way through.

I wouldn't be surprised if there were 50,000 AMG blocks in HMMWV's now.

The fellow selling the mil. surplus engines said the military was pulling the NA 6.5's out of vehicles, (I'm assuming the HMMWV's), and installing 6.5 TD engines. The new ones he has are spares that were no longer needed. Said he had some rebuilt NA 6.2's also.

[midniteplowboyy]

That feller lied. We install around 32 new AMG 6.5N/A engines a day into HMMWV's.

???? First time I'd ever met the guy, and yeah, maybe he's a BS artist. The engine on display had all the looks of a new factory engine and was sitting in the bottom half of an olive drab military looking shipping container. Anyhow, I've got to head back overseas to work for 4 wks. and will go over to his place when I get back. He's just right over in the next county. He said he had 15 6.5's available and would put one of them on the dyno and run it for me before we made any deals. He can do the R&R of my old engine with his new one also. I won't have time to fool with it, but am very careful before laying down that kind of money. I'll post here how this thing comes out when I get back home. Thanks for all the input.

He has been getting the motors from Govt. Liquidation, I bought two "Rebuildable" 6.5's from Gov liquidation back in 07 for 250.00, Both had thrown a rod due to a blown head gasket. One of them a 98 block which in the process spun a main bearing and ate the crank up I sold for 500.00 and the other a 2000 or 2001 block (Thickest GM Casting been a minute since I looked at the date code) before AMG took over I have sitting on an engine stand torn down waiting to be rebuilt. A quick way to tell scammer from something that could be legit is does it appear to be freshly painted? The heads are usually the telltale as the front and rear "Accessory mounting surfaces of the head should be bare metal, You should also see factory "Paint" inspection dots on these surfaces, these can be multi colored and are about the size of a dime. Look where you accessory brackets would mount up for these. If it is a "New" motor andt if its not an "AMG" it should have a "General Engine Products" label which was the division of General Motors whom produced the Motor for the Humvee affixed to the drivers side valve cover. If it has been freshly rebuilt from the government than it should have a Mylar (Aluminum type sticker Material) affixed to the valve cover with a date of rebuild stamped on it. The timing cover is a dead giveaway usually as well. If it is anything other than Bare aluminum then it has been rebuilt or painted in a non-factory manner. I have bought several items from Gov liquidation and have seen "New Old Stock" Items surplused off at extremely cheap prices, I have also seen people buy Junk at these auctions throw some paint on it and sell them for new prices. I have talked at length with the DRMO People at several of the bases waiting for my turn in line to claim my lot, They are friendly and most will tell you what is and isnt junk and what to watch out for. Most all of the Military Surplus motors New and Used come in the Shipping Containers, The containers themselves weigh 500 lbs a piece.
