TR 4 Norris Cam 342S Spec Sheet

I am rebuilding my TR4 race engine and was trying to find a spec sheet for a Norris 342S camshaft. This is a pretty high lift cam which I've had for years and in great condition. Norris is out of business and I don't seen any reference online. Thought I would take a stab here.

Thanks

If i was you i would think about the high lift nature of the camshaft, if its not it's compatible with your engine setup and racing aims it could be a nightmare
