Gmc crackerbox drive
For those of you that asked for a driving video I finally got one. Just a short clip around the neighborhood. I'll have a better one soon

1951 Army truck pulled from building after 30 years storage.
I decided to get this army truck out of my building, after 30 years - - I now have it for sale for $1500 - - - missing transmission, has transfer case yet; 99% rust free. I had planned to install a 6-71 Detroit diesel in it with an Allison automatic. I might still do that if no one wants it before that. Still has the 302 GMC 6 cyl gas engine though.

GMC Crackerbox
Though the Historic Vehicle plate says '77, I'm not sure if that year is accurate to this truck. I don't know nearly as much as I'd like to about these old rigs. I did hear the owner tell another guy that it had a 318 (Detroit Diesel 8V71) in it. Unfortunately I didn't get any video of this neat old Jimmy running. Shot on February 11th, 2012 at the Arizona Early Day Gas Engine & Tractor Association Show in Glendale, Arizona.

8V71 Open Exhaust in french GMC Astro
Un route de campagne Lorraine, un bruit infernal : Detroit Diesel in action ! Un copain me fait faire un tour avec sa dernière acquisition... GMC Astro de 1974, ex transport Marmeth de Nantua. Le moteur n'est pas un "banal" -6V92T mais bien un vrai V8 sans turbo, un rageur 8V71 qui permet une conduite sportive, et libère pleinement en échappement libre.

Cannonball A tribute to the GMC COE
This is meant as a tribute to one of my favorite trucks, the GMC COE's known as Cannonballs. The music is from the series "Cannonball" that aired from Canada in the late 1950's.

GM Detroit Diesel 6-71 Engine Motor Running and Shut Down 2 Stroke THD 4512
Same engine as previous video (please see that one also), increasing RPM. She blows a little smoke, but not bad for being a 1953. Todays junk won't run 50 years from now, so I really take my hat off to this one. Being 2-stroke, she revs up pretty quicky, almost tipping the entire engine/bus frame over! Would be a lot of fun in a rat-rod, log splitter, etc. Nothing sounds like these anymore. This was one of the only truck road sounds people heard from basically 1940 to 1990. This engine will not see a smelter as long as I am alive. 12 volt, reverse rotation. Oil pressure shows 15psi at idle, which is more than enough (increases well with RPM).

A Second Look Under The Hood Of The 1947 GMC 6-71 Powered Diesel Truck (Passengers Side)
Here is another short clip showing the GM diesel in this '47 GMC. I don't know much about this truck or it's engine. Obviously it is an in-line six and it said General Motors on it. I think it might be a Detroit Diesel 6-71. Someone said it was an old PT Boat motor. Shot at the Truckin' For Kids Truck Show at Irwindale,CA. 10-23-10.

GMC 671 engines running
This video was made at the ATHS national convention in Huntsville Alabama this past May. There are five GMC cracker boxs with engines running at the same time. That may never happen again as they are getting far and fewer between.
