Cam Help

Alright guys i recently found a set of cams for my 77 1000, but... i've got no idea who manufactured them or what size they are. I did measure the lobe and it was a hair over 38mm, pretty much 2mm over stock lobe size.

On the cams it has CWC engraved on it and also says made in USA.

Any ideas on what type of cam this could be or how much of a performance increase i would get by installing these? Or a better way to determine what the specs on the cam are.

Measure across the base part of the cam and then measure the total lobe height. Subtract the base measurement from the lobe height measurement and this will give you the lift of the cam. If you can do it in inches with your caliper, it will be easier to tell.
