BS, if I decifer correctly, that military truck wont have the overdrive trans so the fuel mileage wont be as good as a civilian model.

All I know about em is that diesels are loud and they stink.

I think it was penisular desel that had the marine kit for the 6.2/6.5. Mercruiser marinized the VM diesel( formally BMW Marine), the 7.3 Navistar, and now with their partnership with Cummins, the Isuzu 1.6( the Cummins *engines were allready marinized). they have just introduced soome new enmgiens that I haven't had time to look at.
I used to work for a manufacture that built large street sweepers, we used the 6.5 NA (no ***) normally asperated engine in our twin engine sweeper( the 6.5 didn't have enough power to run the hydraulics and push the truck. We got a deal on a bunch of them from GM, but with no warranty. We put the engines in the trucks and drove them to Rocky Mount from Wake Forest ( about 90 miles round trip) to check them out, half the engines didn't make it. They had so many problems with them we ouot thermocouplers on the *heads and found the temps around the injectors were getting so hot, it was holding the injector stuck open, when you backed off the throttle it hydrauliced the motor kicking the rods and crank out in a spectacular fashion. We cut one head up in 1" slices to inspect the cooling passages, the passages were so restrictive it was causing cavitation and isolated heating. We went back to using the 5.9 Cummins and 7.3 Navistar(its only a powerstroke if you stick a ford sticker on it). I've allways be a fan of GM vehicles, but i'd have a hard tiem buying a 6.2, or a 6.5. they are just outclassed by the Cummins(not Dodge) and Navistar(not Ford).

Anyone tried to put a Yanmar in a pickup?
Take a look at Yamaha Marine International website, they are marketing their sterndive package with diesel engines for the European market, too bad we can't get them here. *

GM 6.5 marinization kits are built by these guys out of NEW YORK. And I'm pretty happy with my 6.5, needs headgaskets right now, but it's my fault(that hypertech sure made it scream though :o).

for some reason, i can't get Pensular Diesel spelled out on my post, it keeps coming up "thingular". It was Penisular that marinized "the Beast" as it was called. Theres a company called US Marine Diesel (i think thats the name)that still offers the 6.5, the tooling was sold to AM General to continue producing the motor for the military after GM dropped it. They completely redid the tooling and improved the engineso it would hold up in military trim, they offer the 6.5 in a supercharged *version at 425 hp

weird, it spelled "thingular" again, after i changed it twice.

The sensor thinks you are trying to type the word for "male member" and its changing it to "thing". I tried to call something the slang for lady of the evening the other day, it came up "sleeper".

PENINSULAR was the first to marinize a GM diesel. The old 6.2's. GEP is currently building the 6.5 for the military using the INTERNATIONAL castings(yes the same company that built the 6.9 for FORD). They are casting them under the name OPTIMIZER 6500. They are supposed to be releasing the new military MIL SPEC engines here soon with the forged cranks(rumored to be LUNATIS work) and even more block and cylinder head improvements.
