Introduction of the Panhead. The Panhead was a different top end on an existing bottom end. The E and F designations remained. This is the first and last year for chromed Pan covers, as subsequent years would be stainless steel. Panheads were made to improve oil flow and consumption. One of the biggest advances was the hydraulic lifter, which meant less adjusting, and a cooler running engine. The frame would need to be stretched to accomodate the taller engine, and was designated the "wishbone" for it's bowed downtubes.
