VALVE CLEARANCE

Or just dont talk to less than par people who do not understand simple physics. LOL Ramp speed is how fast..........WHEN "as you put it" is duration. Two different things. ha ha ha ha.

Ok. A pitcher pitches a fastball. Then a slowball. Which one gets there first? That's WHEN. Sure, duration is how long the valve is open. But if you compare a slow ramp to a fast one, the fast one will get TO that duration FIRST.

Lesson over. Now go back to designing cams.
