351W will have horizontal fuel pump bolts.
351M will have vertical fuel pump bolts.
(Amoung a few dozen other differences)

Valve cover bolts:
351M/400 uses 8
Windsor uses 6

Cleveland has a dry intake - upper rad hose goes into the block.
Windsor has a wet intake - upper rad hose attaches to the intake manifold.
