These non-oiling chrome moly push rods fit 170/200ci motors with non-adjustable rocker assemblies. Chrome-Moly push rods are lighter and stronger than regular steel push rods. The tubing offers maximum strength to maintain a no flex operation at higher RPM's, under the stress of high lift cams and high-rev valve springs.
NOTE: Due to the different deck heights, head milling, and gasket thickness, Classic Inlines can not garantee that these pushrods will be the proper length. The best way to make sure you get the right length, is to assemble the valve train first, measure the pushrod length with an adjustable pushrod, then order the pushrods.
