Another example of a "big bore/short stroke" engine would be a 235 bored .060" oversize to 3 5/8 inches, with a 3.25" destroked 216 crankshaft- - - - -201 cubic inches, and a very high-winding RPM capability. With the right combination of properly weight matched lightweight pistons and rods, and smaller than standard rod and main bearings, the engine should be capable of continuous operation in the 4K to 5.5K RPM range.
