Exhaust Camshaft
Exhaust camshaft for the engine bottom end, cataloged as 70-9983 (also E9983).
This is the exhaust camshaft, listed under part number 70-9983, with the older E9983 number showing up in earlier parts books. The catalog places it in the crankshaft and connecting rods section of the engine, which is where camshafts get listed alongside the bottom-end components they work with.

A camshaft like this one controls the timing and lift of the exhaust valve, riding in the crankcase and driven off the timing gears. Its lobe profile is specific to the exhaust side, distinct from the intake cam it runs alongside.
Our record only ties this one to a single catalog year, 1970, so before you order, check it against your own engine to make sure it is the right cam for what you are working on.
