351W black casting

[snake428CJ]

I am in search of a 351W block/motor. What is the easiest way of telling if it is a 351? What kind of casting numbers should I be looking at on the block?

well in the valley it will say 351, roller motors have f4 castings (used from p4 to 97or98 i think) and they have a taller deck height then 302s.

F4 will just mean its a 94 part number.
