Your methods leave something to be desired for measuring piston diameter, lol, but I would guess its a 4 3/8 bore 451 with a 383 rod length for a lo-deck.

The pistons you found are 4.360 dome ross pistons, 3.75 stroke. I know because I was kicking around buying them and the seller sold them. Hence the reason you cant find the ad.

With the RB cast into them its a sure bet that they are not for a low deck. mike

They sure have Ross machining characteristics but, it looks like their forging supplier ran out of that particular (Ross) blank since the name has been machined away inside.

They would make good ash trays from the looks of them.
The rest of them are really nice just this one has a few boogers on it. If i can figure out what they are i was gonna order a replacement piston for this one.
