57-66 283/327 base engine and powerpack cam for 195, 220 hp 283 and 250, 300 hp 327 is casting number 3733431, part number 3732798. Hydralic lifter with Intake lift .398, Exhaust lift .398, intake duration 300, exhaust duration 300, rocker ratio, 1.50. this cam was replaced in 67 with 3896929. The Sealed power replacement cam is CS-274, much cheaper and just as good as the GM OEM cam since Sealed power makes the cam for GM. Get it at NAPA or whever Sealed Power products are sold.
