I know how cams work as such but I'm wondering if the lobe bit opens or closes the valve.
A 280 degree cam is that 280 degrees of closed valve or open valve?
Sorry to ask a dumb question but I've seen videos where it shows valves open and close when the widest point of the cam lobe is in contact and they can't both be right!
