On late '77 and later engines, the pitch diameter on the camshaft, pinion gear, and breather valve gear was changed. These components are not interchangeable with earlier styles unless replaced in sets. Late '77 and later gear sets are identified by a circular groove machined in the outer face of the cam gear.
