shot peening a distributor gear for a roller camshaft

A billet hydraulic roller
Wow ok interesting.
The cam manufacturer recommended a melonized gear not bronze?
I mean I would do whatever they tell you
Just seems odd to me.
every Billet cam I've ever used was always told to run a bronze gear.
But those were Billet Solid Rollers...
not sure why there would be a difference
Solid vs. Hydraulic Billet
But thank you, I might just learn something.
Carry on
