It might be too early to mention this but there is a possibility of new nodular iron blocks for the Y. Lots of improvements including drop in lifters, 4" bore and maybe even longer strokes.
NO, it isn't me thinking about doing this and it is definitely not a certainty at this point.
Just something to get y'all thinking and I must say it would be cool!
