I was wondering if a 40 hp Kohler Command Crank, being a 63 mm stroke, would fit in a 25 hp block, normally being a 63 mm stroke. With or without, too much modifications. Is the valve height, from the deck, about the same on the heads? Will I have to cut the bottom of the cylinder wall out for the rotation of the crank weights? Trying to build a stroker engine. Looking for the low end, 3000-5000 RPMs, torque of an under square engine. Any help would be greatly appreciated!
