48 New Yorker Posted May 19, 2022 Report Share Posted May 19, 2022 All the pistons on my 48 New Yorker are stamped with "STD", indicating the standard bore. Do they come stamped this way from the factory as originally built, or are they replacement pistons (in a standard size bore)? Quote Link to comment Share on other sites More sharing options...

A thing to watch is that some replacement pistons are "rebuilder" type. The compression height is about .02 lower than regular pistons. Should be 2.00" and not 1.980 or 1.978. If you are not having the block decked it's important. Quote Link to comment Share on other sites More sharing options...
