I recently came up on a few Detroit 6V53's that were pulled out of some equipment at work as the result of a re-power.  They're mine if I want them.  I have a lowered '77 Chevy C30 dually that I was thinking about re-powering with one of these units.  Nothing serious, just thought it would be a fun novelty that would beat the pants off the fuel mileage of my 454.  My Dad has an '86 C30 he was thinking about re powering as well, but he wants more power for towing his 5th wheel.  

Can anyone point me in the right direction for info on these swaps?  Anything I need to know?  Anyone been there, done that before that would like to impart some knowledge?  

Tranny tips/advice?  We both would love to ditch our T400s for 6-speed manuals.

Well i did some looking around. I think you will need to lift the truck and beef it up a ton. The 6v53 weighs 1860lbs is 40in wide 40in tall and 53 in long. From what i hear you will need a truck 10speed for a trans and nothing less the a 2 1/2 ton differential and a huge driveline. Usaully swaps like this require a big lifted truck to get the engine low enough to fit under the hood and still provide oil pan clearance. I hope this helps if you have the time and resources I say go for it and good luck.

One more thing you will need to check rotation on that engine they were originaly designed as a marine engine and they rotate backwards.

Hmmm...Maybe I'll just sell them on Ebay and pick up a couple of 12 valve Cummins then.  That might be my best bet for what I'm looking for anyway.

However, I don't think you're right on the length.  I took some rough measurements while it was sitting on the ground in the yard and it measured 39 inches from the fan to the back of the block.  Could we be talking about two different motors?  I assumed it was a 53 because it was a 6 cylinder in the v configuration.

Looks exactly like this-

Some of the newer HEMTTs are electronic, so you may not be able to tinker with it.

A 6V53 is a lot of engine and weight for a 1 ton truck, I would not recommend such a conversion.

However, if you must, it would be best to start with a 6V53T, the turbocharged version.  Because if you are going to go to the trouble to fit it, might as well do it right to start with.  Just for rough figuring, a 4-53T is approx the same power as a 6V53, not to mention smaller and less weight.  So between the 6V53, and the 4-53T, the 4 cylinder turbocharged engine is the better choice in most cases.

If you really want to see some pictures of a 6V53T in a 1 ton truck take a look here
I recently had one in a 61 F350, with twin turbos.  The conversion was done in the mid 60's, I bought the truck about two years ago, and drove it from CA to VA.  Then I swapped the original axles, brakes, and steering for stuff from medium duty trucks, (original stuff was way under sized) Rear is now a 12,000 lb Rockwell from a small freightliner.  I made a trip around the country and eventually sold the truck.  While I had fun with it, and the conversion was pretty nicely done, I would not build a similar truck, nor recommend anyone do it. A 6V53T belongs in something stronger than a 1 ton.

For a 1 ton with a Detroit Diesel, a 4-53T is a pretty good choice.

As for transmissions, a 10 speed is nice, but most any medium duty transmissions with the round SAE #2 or #3 clutch housing will work.  In a small truck fast gears and OD are important things to consider, run the numbers through a gear calculator, shooting for 1,800 - 1,900 rpm at cruising speed for a turbocharged 53 series (slightly higher for non turbo).

Try this link for more pictures of my project trucks, both the 61 ford, and a 48 Chevy two ton with 53 series Detroits and Roadranger 10 speed overdrives:
