I don't think the production dates 9way up into the 70's???) are right for those.
Between 1960 and 1965 GMC also made a V-12!!! 702 cubes, not a very high redline (about 3,500 RPM??) mad gobs of torque

The local machine shop had a block for one of those sitting there. They had bored it and the customer couldn't come up with the money to pay for the work. If you see a photo of that assembled engine, most people automatically think that it is just two V6 engines bolted together. Wrong. It's a single block with four heads on it. It was used in semi trucks and other industrial uses. Ah....when gas was really cheap!
