Wiseco Piston 2.702 bore x .640 compression height (incl. piston, rings, & circlips) Commonly used as the piston in stroker Animals, this piston is approximately .004" larger than the stock Animal bore. It is also used in +.140" overbored flathead engines (aka 1982p140). In the Animal, it is used with our #6240 connecting rod and either a stock "Raptor" crank, or ARC's hardened chromolly billet version of that crank, #6581-c. The piston has a thick top that will need to be cut down to your specific deck height. This piston does not include a wrist pin and we recommend the heavy duty #6522 wrist pin in all OHV applications.
