I acquired a Norton camshaft that is stamped T2210, or 2219, or 2213. I can find no listing or reference to this camshaft number. Depending what it fits and the grind I may use it in a 750 P11 engine I am rebuilding. Any help is appreciated. I will attach picts of the cam later tonight. Did some more checking tonight, looks like the cam is for the 500cc Dominator. It is now for sale or trade as it will not work in my 750cc P11 engine. Ed Blount

That number is for the core and not the grind. It will bolt in up to a 20M3 norton heavy twin(early commando). Not 20M3S and up. The profile is still the question...for its suitability. http://atlanticgreen.com/camsurvey.htm not big bucks....

Thanks for the info, I just acquired a P11 so it should work. How can I determine the grind?

As a rough guide you measure across the whole cam/with lobe(base circle + (basecircle and lift)) and then measure across the cam at right angles to the lobe (2X base circle) subtract the two and you have cam lift. Compare to the cams on my webpage. IF stock it is probably the 1S/650SS) grind.
