Does anybody know what is the base circle radius of the Type4 Camshaft?

Thanks

These guys sell a stock size and a 1" base circle camshaft also.

That's a fantastic discussion of the issues and variables and how they fit together, every one of those points the subject of a dozen SAE papers.

thanks to all!

Measure any cam the same way you would turn,mill and grind it,in roller-blocks mounted to your mill.
Use a height guage,or calipers,to determine the radial difference.
Currently,you would map the cam profile with a cmm,or spc sending indicator.
