what cam do I have

I'm doing the lower end on my 47 EL and am curious what cam I have. The only markings are on the face of the gear. At 12:00 is the letter F and at 6:30 is the number 1. Is this a stock cam. If not who made it and what can I expect from it. Bought it in boxes so I"ve never heard it run. Thanks

I suspect, from the base circle diameter, that this was reground.

I measured the lobe from the highest point to the base at 1.22. CC

Re: what cam do I have

Yup - reground. Palmer cites the original 1936-47 lobe as 1.22" tall + reduced base circle = undercut for duration increase.

Summary: you won't know what it it unless you time it with a degree wheel and dial indicator.
