The 565 is based off a CNC machined cylinder block that is stroked for an additional 31 cubic inches of displacement to 533-C.I.D. (8.7 L). The larger displacement combined with redesigned cylinder heads, multiport fuel injection and twin electronic throttle bodies results in a whopping 565 horsepower at the 5000-5400 rpm operating range. All of this power comes from 89 posted octane (R+M)/2 pump gas. The 565 complies with EPA and CARB exhaust gas emissions limits.
