Motorhome 440's... factory seconds?

Know I've seen 440's out of big Chrysler's that have had there main and rod bearing journals turned under sized.

my low buck just dont give a f--k has 20 under mains and rods:D and i dont think anybody has ever been in it. the bearings had .020 and 75 stamped on them.. .still had the thin head gasket that has left the mopar name in the deck when removed8-)
