Hey guys, I'm looking for a set of dome pistons for my 3 3/4 bore 291 in my 560. I've got access to a NOS set part number 530947R91 which is a dome ,,,,my question is ,,,is that the tallest dome or did M&W make a set or possibly somebody else.Any thoughts on this? Thanks

Here is a comparison of the IH & M&W 3-3/4" overbore pistons for the 560 gas. IH & M&W were the only ones to offer the 3-3/4" overbore kit for the 560. The last picture actually has a M&W piston behind the IH.
