GMC General and Chevy Titan90

Yesterday I went to the ATCA truck show in Mucungie, PA. This show happens to be the premiere classic truck show on the east coast. I have hundreds of photos and videos to process over the coming days. Until then, enjoy this great combo shot of an immaculate GMC General hauling a Chevy Titan 90. The Detroit jammed under the cab of the Titan was spotless with amazing chrome valve colors. No oil leaks here. Excited on lookers claim that it was a V12. I’ll take their word for it.

Over the years I have really developed a soft spot for the final years of the GM heavy truck line. These two trucks should give you an indication why.

I only wish I was able to hang around long to see the Titan unload. Oddly enough the General didn’t appear to be DD powered. There was also a perfect Chevy Bison on hand. More on that one later.

    Thanks so much for the great comments and beautiful pictures. The General was built in the last month of GMC production and has one of the first Detroit Diesel Series 60 engines serial number 06R0002128. The Titan/90 is a V-12 and sold new by our original dealership, Lewis Chevrolet.

      I have learned you have one of the few generals with a 60series Detroit in it . I have recently bought a general from a farm in Nebraska and hauled it to my shop in Canada my plan is to put a 60 series ddec2 from an 88 white gmc with a 06r number 8886
      Was wondering if you could send me some pics so I can make it look correct . Hope you can help me thank you

      I just purchased a 1975 Titan 90. Could you tell me where the fuse panel is located?

    Here is the link to a picture of the Titan/90 in it’s first year of operation. It was owned by Henry B. Person of Norfolk, VA. He had a fleet of four Titan/90s and he hauled steel from Sparrows Point, MD. Russell MacNeil took this picture in Springfield, MA. Henry personally drove this truck. One of his favorite stories was, a trucker pulled up beside him and said you got a 6-71 in that thing? Henry said YES on your side!

    If you have trouble with the link go to Hanks Truck Pictures and the Russell MacNeil collection page 21 of his ’70s vintage pictures.

      Awesome pic and story! So the V-12 was original to the truck?

      • Ashton Lewis says:

        Yes to the V-12 being original and the only reason we restored it. It is the only one we sold as they were intended to be used to pull turnpike doubles or Michigan trains. They were considered very extravagant and tough to make money with hauling 45,000 pound payload. The VIN is CDP930V192575. C means Chevrolet and D is for aluminum tilt 6×4. P says it all 12V-71 engine. H for 8V-71 and C for NTC Cummins. There are other engine designations but H and C were the big sellers. This truck costs $12K more than one with NTC350 which was a 20% bump. Now you know why very few built. The 8V-92T with similar power much lighter and a whole lot less money obsoleted the V12. This engine is normally aspirated thus the reason for being so large for the power output of 434HP. The largest transmission was a RTO 12513 which had a 1250 lb-ft torque limit so they were sold with 60MM injectors instead of 65MM which produced 475HP and 1300 lb-ft of torque. We restored the truck with a new Detroit Diesel reman engine clone of the original serial number 12VA30516. In 1986 the third owner of the truck re powered it with a new 8V-92T silver engine to save fuel and increase is payload. I was impressed with Detroit Diesel having the original build record of the engine. I did get them to put 65MM injectors in it since we are not too worried about the transmission failing in truck show mode.

    Just read my post above and need to correct the price bump of a V12 Detroit over a NTC 350 Cummins in 1973 was $6,000. 20 % bump is correct. Besides P in the VIN the left side air cleaner and intake pipe tell you it is a 12V-71. Please also notice on he front of the cab though hard to read, Henry had Dirty Dozen lettered by a sign painter along with a V12 insignia.
