You're best guess please.

I think there are programs for that. I had a coworker who would input the cam, etc and his program would estimate it. I'm guessing that is why @rumblefish360 may be asking...or he is a genius with no need for such a tool!
NOT a genius! Smarty pants maybe…..
Though I will say my dyno guessing attempts here have been, well, not so good.

A desk top dyno that sent a bad program, if your honest and accurate in inputting the specs needed.
