I may check mine up to .120 then after that it MAY give you an idea of how much bigger you could go but that cam may have a different profile.

Good to know. I'm not sure what my builder's range of comfort is. Curious to see what the clearances are on the entire build. .120 seems tight to me but I am probably more cautious than most.... lol
