Next factory size up is a 55 which has the same stroke. It’s a 341” and the bore would be about .140” over yours. Your block would definitely need to be sonic checked for that. Egge Machine in Santa Fe Springs Ca lists your engine as 3.800 bore and supplies piston and engine kits. I’ve done business with them since I live in Southern California at various times and they had what I needed. You would need to call on oversized pistons and rings sets. They Have a catalog you can down load. Kanter also lists engine parts for the 317 and Best Gaskets has set for the 317” Lincoln. Good luck.
