Since the factory crank was ruined when the engine failed on the dyno, an Eagle cast-steel crankshaft of stock 4.21-inch stroke and standard 3.25-inch main and 2.250-inch rod bearing journal sizes was chosen for this project. Here it's installed into the waiting cylinder block. Note the chamfered oil holes for better flow. The crankshaft thrust was set for 0.004 inch. Here you can see the thicker-than-stock 455 bulkheads of the SD block and that the block is not painted. Upon completion, Melvin will professionally paint it with a spray gun, not a can of spray paint. Melvin requested that RaceKrafters not even apply a light coat of primer before our photo shoot, so our engine is not as pretty as normal.
