5.7/350 (250/280 HP)

MerCruiser 350 Mag and 5.7 (carbureted)

Due to higher compression, only intercooled systems are recommended for stock 350/5.7 motors. With an Intercooled ProCharger system, there is no need for internal engine modifications prior to supercharging, and power gains of 55-65% are typical with stock motors running pump gas.
