piston size

I was talking to a buddy about the size of the pistons for the 351 and wanted to double check what I heard. The 351w, 302 and 300 all have the same size piston right? It is just a different stroke? Anyone know for sure?

Bore size is the same for all, but pin height is different, valve reliefs I think are also different between the 300 and the 302/351.
