Man, I love those tiny Dodge Hemis! They're just the right size to slip between the rails of a '30s car. If I was a little closer I'd make him an offer on the engine. It'd move a 2000lb hot rod around "might smart".
Whatever you do, don't scrap it or set it out in the weather.

New reproduction cams for early Mopar Hemi / Poly, & other
engine parts, bearings, pistons, etc.

Gary Pavlovich is interested in the Plymouth Poly, mostly.

Chrysler, Desoto and Dodge each had their own design Hemi. Each family had a different bore spacing. The Plymouth Poly doesn't share bore spacing with any of them. So four different engine designs, no interchange of most any part.
IIRC polys and Hemis from the same engine family shared intake manifolds.
