Looking for Horsepower Guesstimates on Friend's Build

Correction on your Howards hydraulic roller camshaft #720555-12 Advertised Duration 282/288, the Lift is actually .520/.530

Don’t go by Summit Racing’s website.

THIS is the kind of info I was looking for. My buddy has been repeating what he read on Summit's page and not what is on Howard's page.
Anyone care to change their guess now that we have the true cam specs?

Lift: .520 / .530, Duration @ .050: 229 / 235, Centerline: 108, Mild lopey idle, Street/mild bracket, Good low to mid-range performance
