I read an article somewhere about souping them. I woul;dn't go through the trouble as acording to the article I get more umph out of my small blocks than they do out of one of them, at least more drivable umph. Maybe it is good for shock value. A lot of that whole shock thing going on these days.
There's a company reconditioning these engines and selling them for these kinds of balls-to-the-wall projects. http://www.thunderv12.com/ Lots of threads about these GMCs here on the HAMB.
That's exactly how GMC made it. This motor descended from what was originally designed as a diesel, and while it has gobs of torque, it's all done about 3600 RPM. The six also was only good for about 12 MPG loaded or empty, so the truck in the first post probably is lucky to run a quarter mile on a gallon of gas.
i actually have one that i took out of a early sixties fire truck tanker with 16k miles on it. it has one distributor that forks off to accept two of the v-6 caps. it appears to have used all parts from the v-6, heads, intakes, exhaust manifolds, gmc just built a differnt block, crank, and camshaft. from what i have read, the pistons are the same as the v-6.
Distributer. If I was gonna have a special sign made up I'd first hire a second grader to make sure my spelling was done real good so people dint think I was stupit.
wow a whole 250 horsepower! ford gaa v12 dohc tank engine made in 1940 made close to 500 horses and 1350 fthe oot pounds of torque @1440 pounds combat ready but only 900 ready to run!
The biggest truck motor I know of is in my buddy's tow truck. It is a Hall-Scott 1096 inch gas inline-6.
Many moons ago had worked on a 2000 CI V8 in a Oshcosh Snow Blower plow, it was the blower motor for the plow, a m***ive engine over 6" pistons and ran on gas. If I remember right it took 18 gallons of oil......... you could lay in the valley and go to sleep..... don't ask me how I know......
