Looks like two V6's having sex

 

Thats pretty much what it is..

 

I found this info from Wikipedia "The 702-cubic-inch (11.5 L) V12 "Twin Six" was offered in United States GMC commercial trucks, and as a special order option in Canada. It was often mistaken as two V6 engines welded together but in fact was a single casting.[1] It used two separate exhaust manifolds, two separate distributor caps driven off of a single distributor drive,[1] and other parts from the 351. 56 major parts are interchangeable between the Twin-Six and the other GMC V-6 engines to provide greater parts availability and standardization. It produced 250 net SAE horsepower (190 kW). Torque was 585 lb·ft (793 N·m)."

hope u like it ..?

this site has pics and more stuff just try to search for "twin six GM"

 

Not bad, more then I have gotten thus far.. Thank you

 

That's weird that someone brought this motor up. A buddy of mine has one mounted to a trailer and takes it as well as hundreds of other motors to tractor and engine shows. If you have any technical questions about this PM me and I'll find out. Also, send me your email and I'll try to get some good pics of his shortly.

 

I like this video best, I could see putting a pickup bed on that truck.
