Racing Piston Rings Hastings racing piston rings deliver race-winning performance in even the most extreme ap- plications. The low tension, low friction design provides unsurpassed combustion seating and exceptional sealing. Each set includes plasma moly, high tensile cast iron top rings; reverse twist, taper-faced cast iron second rings (unless specified), and choice of standard or low ten- sion Flex-Vent stainless steel oil control rings. Low tension oil rings, which make significant increases in horsepower, are for racing only, and are not recommended for nitrous or super- charged applications. Choose from standard or file-fit ring sets. File-Fit Piston Ring Sets

Water Jacket Filler Hard Blok will strengthen an engine block and keep cylinder bores straighter and truer. A specially formulated, cement-based material combined with iron particles, Hard Blok will expand and contract at the same rate as the engine block. One tall fill will fill most big blocks to the bottom of the water pump connection. Hard Blok cannot be removed after it has hardened. Part No. Description HBL860212 Short Fill Unit, Two 6-1/4 Lb.
