assymetrical cam lobe

Opening ramp is different than closing ramp. Rate of lift might be fast open and softer on the closing side.

A symetrical cam has the same opening and closing ramps...

Cam companies tried all kinds of unique designs.

Even going back to my days racing in Jr. Stock around 1970 there were distinctly different cams. We were limited to stock springs and pressures and valve train. Some cams we used could not be run much past 5800 rpm and one would run right up past 6000 with no problem....Stickshift hydraulic cam small block Chevy.
