The problem with big cams and superchargers is that big cams will lower the vaccum substantially, and you will have to get a low vaccuum bypass valve diaphram. I don't know about those cams specifcally. I went with Comp Stage 1 Blower cams, and my vaccum dropped from 20 - 25 inches to 10-15 inches at an idle. I would talk to the cam and supercharger manufacturer to see if there is an issue.
