The Man O'War block accommodates the 4.155" x 4.250" bore/stroke combination to produce 460 cubic inches. Conservatively rated at 575 horsepower, this engine utilizes a high-flowing single plane intake manifold, 1050 cfm Dominator carb, and a roller lifter cam for more aggressive valve action. With a nominal compression ratio of 10.5:1, you can use ordinary pump gas. Each engine is carefully broken in, and then run on the dyno to certify that performance levels meet or exceed published specs.
