Is a MP 509, 292 purple shaft a decent cam on a supercharged motor

As others have said - a supercharger cam is better suited to be on a wider LSA and less overlap than an NA camshaft. I am going to be running a cam on a 114* LSA with around 290/300 Duration - but it is a lazy grind so duration at .050" is fairly mild.

Should run very well on the street with my 8-71.
