• Stock, S&S Super Stock® or performance replacement heads can be used with this configuration, depending on which pistons are purchased with the stroker flywheels. • 89" strokers can be installed in carbureted or fuel injected engines. Note that recalibration of the fuel injection system is required. • Requires a simple crankcase clearance operation and normal piston fitting. • Low cost boost in performance—Add S&S 35/8" cylinders later for 96" engine

NOTES: If ordering replacement pistons for an older 89" Stroker Kit, the flywheels will require rebalancing. S&S Super Stock cylinder heads do not have provision for the stock head temperature sensor. For this reason they are not compatible with fuel injected applications. Fuel injected stroker engines must use stock cylinder heads or S&S performance replacement heads. (See PAGE 52)
