6.2L 350bhp V8 Performance Marine engine rebuilds A glance at the improvement in BHP and specification will show that this engine gives exceptional value for money. Like all Swaymar special series engines this too delivers a lot more torque and BHP several hundred rpm lower down the rev range than its factory replacement counterpart.
