They are pricey for a cast replacement re-builder piston. Set of 8, 440 cast piston, $250. Set of Cast 413, $450. You can get Forged 440 pistons for under $400. Rings cost more too. It just cost more to rebuild the more obscure engines.
Perhaps, but they're not nearly as pricey as some make them out to be. for Keith Blacks, 440 pistons of the exact same family of pistons is 368.99 on summit, the 413 pistons, 429.99. Not that big of a difference.
