V12 from 1960 to 1965 for trucks, the "Twin-Six"; it was basically GMC's large-capacity truck 351 V6, doubled,

Dam beaten lol

I wonder why they (GMC) went away from it. It took 40 or so years for Ford to come out with a V-10.

Was this one of those things that was built way ahead of it's time or was it a one off design that was a freak and never caught on?
