A Mopar part number, yes...even remotely related to a small block Chrysler, no. Chevy deck height, Chevy oiling, Chevy valvetrain angles and locations, off the shelf Chevy rotating assembly, accepts Chevy front accessories, Chevy trans bolt pattern, heads are a modified copy of the Chevy SB2 and RO7. So yup, 95% Chevy, 5% custom, and 0% Mopar. Not one single piece of these engines is compatible with a Chrysler small block. They did have cool Mopar valve covers though.
