Boy oh Boy this stuff adds up to a ton of HP

HP is made in the combustion chamber and results from the combination of chamber design, compression ratio, valve size, valve opening (cam specs), induction and exhuast. You know all those things you fail to mention.

Basically anything other than putting it on a Dyno is a guess.
