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.





Unloading A 1947 GMC Diesel Truck From The Trailer
This 1947 GMC Diesel Truck is being unloaded at the 2010 Truckin' For Kids Truck Show at Irwindale, CA. Some of the guys that had gathered around to watch and that had personal experience with these trucks in their day said that they were "all show and no go" and "that their bark was worse than their bite". It did have a really nice bark, though! I believe it is powered by Detroit 6-71.

1959 GMC DETROIT DIESEL SHIFTING
1959 GMC CANNONBALL. DETROIT 6 CYLINDER INLINE 2 CYCLE DIESEL ENGINE. THE TRANSMISSION IS A 10 SPEED ROADRANGER. TOP SPEED OF THE TRUCK IS 65 MPH. I TRIED TO DO A MIX OF LOW RANGE TO HIGH RANGE AND BACK TO LOW , SOME DOUBLE CLUTCH , SOME NO CLUTCH , JAKE SHIFTING . UPSHIFT AND DOWN SHIFT. SOME HIGHWAY DRIVING AT 50 MPH AND AT THE END CLIMBING A GRAVEL DRIVE ON A 15 % GRADE. THE TRUCK HAS 9000 MILES ON A FRAME OFF RESTORATION. IT IS NOT COMMERCIAL AND DOES NOT SMOKE OR LEAK. IT JUST GOES TO SHOWS , PARADES AND EDUCATIONAL EXHIBITS IN ITS WELL DESERVED RETIREMENT. THANKS FOR LOOKING ! THE JAKE HAS A TOGGLE SWITCH TO TURN ON AND OFF , ALSO DEPRESSING THE CLUTCH OR STEPPING ON THE THROTTLE WILL TEMPORARILY NULLIFY IT. I FLIP THE SWITCH AT ABOUT 43 SECONDS INTO THE VIDEO. TAKE CARE.
