Choosing cam for 5.9 magnum

I agree about losing some base circle.

For just a few bucks more Kenny at Oregon Cams has new cores on the shelf rather than grinding a core. That keeps the base circle the same size.

Same thing I dealt with at Oregon with Ken, so I know for sure this is fact.
I just don't remember what the new core price difference was, but a quick call would answer that.
