Birth of a 1970 Dart Convertible

I'm been holding back a little. My motor is about all done, so the only thing left is to get is the cam, lifters, valve springs and some valve covers. I been thinking about a Comp Thumper cam. It is bored .40 over stock stroke with 70 cc X heads. It figures out to be 9.5 to 1 compression. Any input on that cam? Sorry for not sharing.....:glasses7::glasses7:
