GS1000 Norris Camshafts?

[Agemax]

Never heard of them, are they any good?
Just tore down a spare head for clean up and refurb and found it had standard EX. camshaft and a Norris INLET camshaft.
It has F-375 cast into it, but also engraved into it is "NORRIS 357" with "PDo" next to that.
Anyone shed any light on this please? TIA

after a bit of research, it appears that Norris Barsumian used to grind camshafts, the business then was taken over by Megacycle cams.

Megacycle would do Norris grinds if you asked for them - at least till the late 90's. Triumph were probably the most in demand.

An email to them should give you the specs of what you've got. If it's .357in lift it's a mild street cam.

Megacycle cams dont do emails apparantly, cant find an email address for them and a google search tells me they do not respond to individual enquiries. I will just fit it and see how it runs.

Norris cams were the hot ticket back in the day. We were a Norris distributor. I will look and see if we have a timing card on that cam.
