I bought an new harmon collins S 108 cam for 42-48 Ford many years ago at Carlisle. The only markings I see on the cam are S 8 4. I hope that it is the correct cam for the data sheet I got with it. Cam lift is supposed to be .362 inches lift on intake and exhaust. I will check that at least. Thanks for any info on this.

Normally a Harman-Collins cam will have their logo and a 4 digit process number around the OD of the cam gear flange. Take a look and see if you see their marking and some numbers - that might help.
