Maybe tracked down some NOS pistons, but not sure if they are the correct ones, https://www.ebay.com/itm/284423525763 someone also said Federal Mogul 9845CP. A slightly narrower 1905CP fits some engines, 248, 270, and 302. Main bearings: F-M 697M but Im also not sure those are correct can anyone cross reference the part numbers?
