These economically priced 3 5/8" Big Bore cylinders are cast in alloyed iron for greater strength than stock and offer a lower cost alternative for Big Bore engine building. They are precision machined for a perfect fit every time. The standard length works with OEM flywheels, +.200 must be used with after-market Stroker fly wheels.

Note: All cast iron cylinders are manufactured as STOCK replacement and should not be run at compression ratios higher than 8.5 to 1. Cylinders may require headbold set ZPN231574/231577. Stock headbolds may not have sufficient clearance.
