Default Re: Production years for G and H 6 cly flatheads?

The H and M six engines have the block part number cast above the oil pan rail behind where the generator mounts. H or M are in the part number depending on which block you have. M motors are not common and the ones around here all seem to be from 1953 two ton trucks.
