Title: 1951 Dodge M37
Post by: Wingman on May 30, 2019, 07:59:18 PM
In a moment of weakness, I purchased a basket case...

1951 Dodge M37, 3/4 ton, 4x4 (NP420, NP200, 5.83s)

I'm not sure what the end goal is yet. It really isn't nice enough to restore. I know there will be some purist push-back but I'm leaning toward LS, auto, D60/14b, and 40s for "cheap" drivability. The more proper option would be 4BT, NV4500 but that gets pricey quickly.

What to do, what to do...

Appears not to suck!

what are the tires that are on it? 37s? I might want to talk to you about those for my kei truck silliness that I want more and more badly to work on. I need a barn!

36" Buckshot Mudders on non-split 16" wheels. They hold air but are pretty cracked.

DMV nonsense taken care of.

Tear down has begun. Plow frame and hydraulics returned to previous owner per agreement. Bazillion pound PTO winch and bumper removed to the "sell" pile. Most of the wiring removed.

Winch is about 400# of weight hanging way out in front. Truck is already a pig.

Fired and ran for the first time in 11 years. On to details to make it move: carb, battery, 12v alternator and starter, cooling...

By Tuesday, rebuilt the carb, flushed out the fuel system, swapped in a 12v starter, and wired up the 12v fuel pump. All 24v stuff purged. Put some fresh fuel in the tank, squirted some ether, and it fired, ran, and even IDLED!!!

By Saturday, had the 12v one-wire alternator brackets fabbed, radiator mounted and plumbed, temp gauge installed, and accelerator pedal/throttle linkages worked out.

Nothing left to prohibit a test-drive...  ;)

Now has LED headlights, functional turn signals and parking lights, even dash lights and high beam indicator. Also got the heater converted to 12v. NYSI completed too.

Logging miles whenever I can. Ironing out little nuisance bugs. Always getting waves, thumbs-up, and the occasional salute.

So much fun.

Going under the knife this winter. Goal is to transform it into a solid and dependable 65mph mall crawler with 38-40" tires on a "budget". 78bhp/40mph is only fun for a short time.  ;)

Donor is a 2005 Silverado 2500HD 6.0L/4L80E/NP261/4.11-14bolt/Hydroboost. Keeping the '51 frame instead of doing the sheet metal swap.

Out of curiosity, I weighed each combo

230ci/NP420/NP200 = 905#

6.0L/4L80E/NP261 = 910#

Still puttering away...

After a few in/out battles, cutting away old mounts, cleaning up decades of grease and dirt, it found a happy spot.

Engine mounts done
