i was prepping my old cams to go back into my head, and i was just inspecting them.. and noticed "PR3" on the cam gears. note these cam out of my GSR motor. i tried searching but im just to lazy and tired to continue.

anyone got the cam specs on them? and what about p72 cam specs? and finally, which one likes boost more?

 

ALL b series cam gears are "pr3"

hell even zc cam gears are pr3

 

weird. thanks for the info. so is there any way to tell what cams you have?
