| Richard, when I took the photo of Fred's crackerbox I had never met him (or you). It was quite a surprise when I went to post the photo last night and realized that Fred was in the picture. I had no idea the owner was anywhere near when I snapped the pix. John

You guys have been in that "Large Car Dreamworld" of "cookie cutter" trucks so long that you've forgotten all about the money maker fleet trucks that plied the highways 40 years ago and made plenty of trucking history .
I'm here to tell you young'uns that GMC pioneered so many "truckly" things it's worth keeping in mind for historical innovations . Again referring to my library of spec. sheets on aluminum tilt models,diesel and gas powered ,[Crackerboxes]------ADV dated 7-66 , they show model DE-9500 with the 637 gas V-8 [60 degree] rated at 275 HP @ 2800 RPM , also DJ-9500 with the dreaded 195HP @2600 RPM D-637 Toro-Flow as standard ,with the DH-637 Toro-Flow producing220 HP @2800 as an option in the DJ-9500. The neck snapping torque of the gas 637 at that time was 600 ft.lbs @1600 [similar to the 6-71] , and with the Toro-Flows we had 450 ft. lbs. @ 1800 for the D-637,and 458 ft. lbs. @ 2000 for the DH-637 .

| Check out the Cole Land Transportation Museum website (Bangor Maine). In the Coles Trucks section they have one of the three orginal twin steer crackerboxes built for Coles in the 60's. www.colemuseum.org The truck hauled 3000 gallons of fuel in the drom tank and an empty van box north into Aroostook County; then carted the empty drom tank and a van box of potatoes back to Bangor.

I think what you saying there Dan that we would not got were we are now with out the help of some of those old GMC and even those old toro/flows. I have messed with them some but the GMC dealer here got most of them. I was told that the 637 was what took the place of the V12 702. I was invoved in building 12 new cab over F model macks before mack stopped the dealer from building a new truck from new parts and they got gas burners on propane. We built 6 with v12s and then we was told no more V12 but a 637 was what you had to use so we built 6 with them.That was a large engine. This must have been in 1967. Any way the man that came and got the new trucks as they were ready told me one night that thosv12 would run 300000 on propane and then they would pull all 4 heads and exhaust manifolds and replace with new heads and manifolds and run another 300000 miles.Needless to say these trucks was transporting propane.

Glenn----Correct on the 637 V8 replacing the V 12 702 engines . Local propane dealer,Linden Propane ,out of Cleveland's west suburb of Grafton or North Ridgeville is running a KW with a 903 on propane ,plus still has several KWs with the GMC V 12 on propane . I saw him in September and sounds like he was buying any V 12s he could find .
Clayton------5 of us made a search trip to a couple of junkyards in western Maryland and West Virginia Monday , and the subject of the Cole crackerboxes came up. Although I visited the museum twice 10-15 years ago when our youngest daughter lived in the Bangor area,I could'nt remember if the rear was single or tandem drive . Finding my pictures would be one thing, plus till I got a digital camera ,indoor photos were always poor .

When i went to white in 68 Texaco here had 3 or 4 GMC with that engine and me working nights i would get to work on them and did think at that time i was good with them .Most of the work was tune ups and small things but some guys did under stand the ign sytem on them and i would say treat the engine like it was a straight 6 over here and a straight 6 over there and the wiring on the plugs wires wired that was because of two disc caps.2-3 mile per gal on gas was the nor. The driver would say they ran like a 250 cummins.till flat land then the gas burners would run faster.It is hard to beleive that their all gone.

Can you elaborate on the 903's on Propane? I've heard of some diesels running on natural gas with just enough diesel to control them, but never OTR trucks. Inquiring minds want to know.

Speaking 903s on propane i remenber years ago a core buyer was by our place and he told me the old END864 mack engines was being used that way in the west for pumping water on farms out of deep wells. He would buy all he could find at that time and remenber say well good they need to be taken out of trucks. The inline cummins that i was around on the water pumps was ignited by diesel and fueled on gas or propane. They had i think a low flow injector just hot enough to be a ignition source for control and i remenber they was painted blue.
