sorry to misguide you,,,
That was actually a quote from Ryan Heart,he seems to recommend that cam to everyone,and Im not sure why?
I think the cam is good,not the only cam but a good one. The 383 might need a small base circle cam,depending on the rods you use.My 434 needed a small base circle cam.
also??? have you considered a 4/7 swap cam?If you plan to buzz the engine there are claims that the 4/7 swap is a little smoother
