The crankshafts are forged from 4340 alloy steel, come with or without center counterweights, and are available in six different strokes that range from 4.000” to 4.750”.
Manley’s Platinum Series pistons have bore sizes up to 4.625” and a possible displacement of 632 cubic inches. The pistons are forged from the preferred 2618 alloy aluminum and available in dish, flat-top or dome designs to provide from 8.1 to 16.6:1 compression ratios, depending on the combustion chamber size. The domes are compatible with popular aftermarket cylinder heads. Manley’s race-proven 4340 forged steel H-Beam connecting rods are included, and are rated at 900 horsepower with the standard ARP 8740 rod bolts or 1500 HP with the optional ARP2000 cap screws.
