Norris Magnum 70 Camshaft

Postby Joda » Fri Mar 14, 2008 9:06 pm

Does anyone have any information on a Magnum 70 camshaft that was made by Norris for the Commando? I have had one for a long time now that I purchased along with other bits. I would like to install it in a 74 MK2A that I am currently building but I don't have the timing specs needed, nor any other useful information.
The lobes measure approx. .375 on the Intakes & .345 on the Exh.
From my info it's close to the Combat cam .390 In & .356 Ex, but I,m not sure of the durations.
I would greatly appreciate any information anyone might have to offer; oh, and by the way, no, it isn't for sale.

Ther are a load of cam profiles here"

But none seem to be the one you describe.
If you have a look through them you may find a similar one to use as a starting point.

I was under the impression that the Norris mortorcycle cam business was sold to MegaCycle years back. You might try contacting MegaCycle as well.
