The link shown is an excellent resource, though not entirely complete.

If the engine is as-built and has its original serial number plate, the beginning numbers indicate (generally) the engine's displacement. However, if the top of the block has been milled to re-level it,  the original plate may have been lost. They also dissolve when the engine has been chemically dip-cleaned. 

The engine may have been rebuilt modestly or significantly during its lifetime, which may also change its actual displacement.

.How do tell the difference between the engine sizes? Are there marks on the block to look for?
