Keep in mind, engine circa is usefull but many engines have had other cams installed too. So it is entirely possible to have a steel cam in a later block and a cast cam in an early block, the fool proof way is to look at the gear on the cam and then match the gear on the distributor.

See Dave's tutorial:
