So given that, I would guess the crank gear can be swapped to the crank sprocket??? Maybe one would have to source the 3.86 stroke crank from/for the 379 V6 to make it work out?

Yes, you are correct about the 379, completely forgot GMC made one of those. Good news is the 351 and 379 both had chains. Your on to something now. It should work if the crank is out of 379. Not sure of how to calculate what the compression ratio would be. Too bad the 379 was a one year wonder, only available in '73, it is a very rare engine, GMC discontinued the V6 gas family that began in 1960 in '74. Just imagine if you could find a great running low mileage 379 out of a '73 GMC farm grain truck!
