Cool motor, what did it end up making for power? That would be great for a street rodder who doesn't want a belly button engine.
Regarding the statement in the article that the poly was the forerunner of the Hemi, I wonder what they mean? The Hemi was Chryslers first V8, introduced as a 331 in 1951, but the poly didn't come about until 1955. It was introduced as a cost saver, using only 1 rocker shaft per head, and thus a smaller head casting. All 3 generations of Hemi heads use 2 rocker shafts and have nothing in common with the poly.
