From Grigg :

It's been a few years since I've updated Gallery pages. For my 1948 Chevy 2-ton, there is a lot to tell!

My current project is re-designing and building a 1948 2-ton Chevy truck with a 5 window cab and a Detroit Diesel 4 cylinder two cycle engine. It uses the running gear previously tested under my 1-ton (1952 Chevy 1-ton pickup with 9-foot bed). So far, this conversion (still unfinished) is already on its second 4-53T engine.

The first Detroit Diesel engine came from a low mileage 1978 GMC 6500. Then with a chance to upgrade to a newer, extremely low hour "Silver" 4-53T, I decided to swap for (in my mind the ideal engine) the one I had been looking for from day one. It looks and fits the same as the first, yet has some internal improvements for more HP, longer life, better efficiency, and reduced noise.

The Silver engine also has Jake brakes installed, as seen (and heard) in this video.

The transmission is a Fuller Roadranger model RTO-6610, a ten speed 0.80 overdrive transmission. This is also the second transmission it's had. The first was a non-overdrive version.

The following is a list of some of the things I plan to do and add to the truck (same as before pretty much):

• Detroit two cycle 4-53 with turbo
• Roadranger 10 speed transmission
• Intercooler
• Ingersoll Rand air starter
• Dana 70HD rear with an ARB air locker and 3.53 gears
• Hydrobooster for power brakes
• Cruise control
• Air conditioning
• Leather seats
• Sprayed in bed liner on cab floor and under cab and fenders
• Custom made original styled aluminum flat bed
• 9r22.5 tires
• Red paint

      My current project is building a 1948 2-ton truck with a 5 window cab and a Detroit Diesel   I will use the running gear from my 1-ton under (1952 Chevy 1-ton pickup with 9-foot bed) my new 2-ton when finished.  I have found and installed in the frame a 4-53T Detroit Diesel with Jake brake.  I have a Fuller Roadranger model RT-610 ten speed transmission I will use until I find an RTO-6610 overdrive version.  The following is a list of some of the things I will have on my truck: 

Detroit two cycle 4-53 with turbo Roadranger 10 speed transmission Intercooler Ingersoll Rand air starter Dana 70HD rear with an ARB air locker and 3.53 gears Hydrobooster for power brakes Cruise control Air conditioning Leather seats Sprayed in bed liner on cab floor and under cab and fenders Custom made original styled aluminum flat bed 9r22.5 tires Red paint

    When complete I will have a very capable diesel truck with most of the comforts of a newer truck. I should get mid 20's mpg empty.
