The rotating assembly in this engine looks as good as it works. The pistons, Oliver 6-inch rods, and crank were all coated by Polymer Dynamics (PolyDyn). The crank was treated to lightening, knife edging, and was machined for 2-inch diameter rod bearings. Then, it was chromed (for increased smoothness and less overall drag on the bearings) by Crankshaft Specialist. The crank and rods received PolyDyn's oil shedding coating for less drag and weight while spinning. The piston pins, piston skirts, and all bearings were coated with PolyDyn's dry film lubricant to minimize friction. The piston tops received a thermal barrier coating to improve heat retention in the aluminum-headed cylinders.
