How do you tell the difference in the 351w and the 351c?

There are different ways. One is that the 351w fuel pump bolts to the timing cover,the 351c bolts to the engine block. Water flows through the 351w intake manifold and does not on the 351c. The 351w has inline valves and the 351c has canted valves. The 351w has squared intake ports and the 351c has huge round ports. Hope this helps some.

How do you tell a 302 from a 351w and a 351m?

The simple difference between the 302 and 351w is simply deck height. The 351w is taller. They share a majority of interchanging components. Both the 302 and the 351w have a water cooled intake meaning a water bypass hose between the water pump and intake. The 351m would have an aircooled intake meaning no bypass hose. Also the head design of a 351m would make the engine look a lot larger (wider) than the 302/351w
