GMC ALSO MADE A V-12 diesel guys. 2 6-71's siamesed together. mostly for generators, but there were some big trucks-----------------!!!!!!
spanky, i saw 1 and only one 3-71 in a cabover smaller than a 520, but i ain't sure it was stock.
it was in a custom carhauler.
i've always wanted a cannonball. gas or diesel.
by the way, remember how they got their nickname?
