I'm thinking I put too small a cam in my 360 Magnum...

With the goals in mind, it’s not going to be an issue if you’re spraying it. Traction is going to probably be the limiting factor, so if the cam bleeds off some dynamic cylinder pressure, it will probably help more than hurt. It’s plenty of cam for the application. What’s the installed ICL? I’m guessing 216/222 @ .050 going by crane’s typical lobe profile.
