Small Block Oil Pans

Are all small block, LA, oil pans the same for the 318? How about for the 360? Like stock replacement Milodon pans. I see them for sale cheap and that gets my greedy part hoarding feelings going. But when I look them up, they don't list that they're compatible with M bodies.

Not that I would buy one for this turd engine. But I'd hoard one for later
