The rods connecting the pistons to the cranks are forged small-block Chevy units from Oliver. They measure in at 6.2 inches in length, and weigh 660 grams. Pin diameter is .927 inch (small-block Chevy OEM diameter), and the big ends are finished in factory SBC 2-inch diameters. Like the crankshaft counterweights, the connecting rods are coated with PolyDyn PD-14 Silver, an oil-shedding coating that will not allow oil to stick to the parts. This reduces parasitic drag on the rotating assembly, hopefully allowing the engine to rev quicker and smoother.
