I am looking for more detailed specs on a cam that Herb sold many years ago.
The numbers I have are from the end of the cam.
cc 320/320 55 cc z8771 h8 . I ran one of these for a season, and it made great power. Unfortunately I no longer have the specs, and a friend bought the identical cam and would like to know more about it.
It is possible that this cam is 268 degrees at .050, and has .540 lift with a 1.5 rocker if my memory is right. Anyone know the correct duration at .050 and the LSA, plus the recommended centerline?

I think the lobes you're asking about are in the attached list.

From what I remember, McCandless had them ground on 108 and used them for low maintenance bracket engines.

I think it's a Compcams grind 21-320-4. 320 at .006, 268 at .050, .540 lift at 1.5 rocker ratio. ground on a108 lobe sep. 21-245-5 grind is the same as above but with a 110 lobe sep.
