FWIW - As I recall you have a 360ci engine so the following would apply. IF the displacement is different than that, different factors for the peak power calculation would be required.



Take the intake airflow number at peak valve lift and multiply that times the factor 2.08 (if the flow bench testing was at 28"H2O test pressure) and that will give you a Hp potential number for the engine. That flow number will decrease when the intake manifold is put into service, as the loss is unknown unless the guy tested it with the manifold in place and you have those numbers.



Next you can estimate the peak Hp RPM by multiplying the factor 29.444 times the airflow number used above. IF you were not using the square nose dwell type camshaft, that factor changes to 26.578


Hope that might be of use to you and others as well. IF not, you could easily add this to the blah blah blah comments.


Good luck anyway!
