3764476 = 56-62 truck block

Block date: A88 = Jan 8 1958


217 in the engine serial number location on the block?
Some sort of replacement-engine code?


Maybe others can provide better information?
Is there really such thing as a from 56 to a 62 block? There is a caution notice in the factory shop manual, 1958 truck, page 8-10 to not install early 1957 mechanical tappets in 1958 six cylinder truck engines. So there is a difference.
