    Alright... A guy in the nearby town has a 1952 GMC military 6 wheel drive truck with a 2.5 ton (at least thats what he thinks) chassis, and an ORIGINAL FUEL INJECED SUbMERGIBLE 6 CYLINDER! Now, does this mean what I think it does? Will this engine run underwater? Would this think go through some [censored] w/ 40" mudders? Does 2.5 ton sound like the right rating for this truck? Finally, there is no box and there is no rust, but it is dinged up a bit. The guy wants $1200 for it and he said that he will take less. What do you guys think? BAD ASS?

    Later,
    Derek

    Sound's pretty good. There was 48 chevy 6x6 for sale around here for 600(cnd). I don't know about fuel injected submergible 6 cylinder engines so I can't really respond to your question. What size tires does it have? Is the 6 cylinder engine strong enough to run 40's? I'm guessing that it would be a trail(mud) only vehicle so I don't think the looks would matter that much. If you paint some camo on it, and run 40's it would look pretty damn cool. In a fourwheeler from about 2 or 3 months ago, they had this huge 5 ton truck from Alakska. It had no suspension (axles were welded to the frame). It was twice as high as a lifted jeep. Pretty cool.

    Damn! I think you could make a bad ass rig from a 'deuce and a half'. If it's a 6x6, it's most likely rated for 2.5 tons, but i'd make sure, just look at some military vehicle sites ( i have some bookmarked, but they're on my other computer). You'd probably want to drop a bigger engine in though, I'm not to sure about the HP or torque of the six but i think the top speed is only 40-45 mph.

    I've heard the same things about the 6 cylinder in those. They live for quite a while if looked after but if you over-rev them you're just begging for rods to come out the side of the block. I believe 2800 RPM was the number I saw.

    I want one of those too, I wouldn't have to sit in traffic to go to school. What's the MPG on it?

    If it ain't a Chevy, don't raise it up!

    These old 2.5 ton 6x6 military trucks were nicknamed "Deuce and a halfs".

    If all the mil-spec parts are still on the engine and it has the tall intake snorkel, then yes, it will run underwater. I saw a video several years ago of one being driven across a lake that was about 6 to 8 feet deep, with the driver wearing scuba gear. It was pretty wild looking!

    MPG? Think low single digits. That is one VERY heavy vehicle, geared extrememly low. It was made to move heavy stuff and personnel damn near anywhere. Mileage was not a big consideration.

    The coolness factor is a 10. The reality is that you wouldn't want to have one as a daily driver [​IMG]

    If it has the stock military tires on it most likely they are 40" tall.

    Picture that thing with the rear axle, and the back part of the frame hacked off, and the bed shortened accordingly. That would drop a bunch of the weight, and IMO, it would look kick-ass.

    That's some fine photo doctoring Blazer1970. That'd be pretty kick ass.

    That'd be REALLY slick, especially if you relocated the tanks, steps, and battery boxes up and out of the way. I saw one at a government auction that had a PTO winch on the front the size of a damn 55 gallon drum (slight exaggeration). [​IMG]

    if the axle in the duce and a hafe you are looking are rockwell they have 6.72s in them and are double reduction top loaders that you can put pantrey hubs in to get like a 20:1 reduction

    and you could unbolt the back axle and cut the bed and make it a 4x4 real easy and that would drop 1500 2000 lbs form your rig( the axle is 700lbs not sure how much hafe the bed a sepention is)

    if they are GM 2.5 axles I dont know jack about them

    its not quite as simple as "unbolting a single rear axle" Both rear axles share suspension parts......like a tandem trailer. You would need a complete front susp, or something of another doner truck. The nice thing about these is they have flat frames, so anything is possible. I'm no duce expert but I believe the pics posted so far are not a GMC, watch some Audie Murphy movies, those are the GMC's.
