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

What does the rest of the combination consist of? If it actually has enough compression for the engine to properly work with that cam (at least 10.5:1, maybe even more!), then it’s not going to work too well with a blower.
Well, there are ways to do it, but it requires something more than most typical 360 long blocks floating around out there....
Good point but possibly the horse before the cart here.
