mbracer,

You have access or a good relationship with the guys at Comp Cams? I have been thinking of having them come up with a good cam for my C43 along with valve springs.

What are your opinions on this? Is there room to increase the valve acceleration rates to open the valve quicker?

Also do you know the valve stem diameters of a C43 valve and the stock cam specs?

I am becoming convinced that I what to build this motor provided I get my Supersport and Superbike race motors done.
