Will it make 500hp?

Hydraulic cam recommended by Jim @ RB
I have not had the heads flowed nor do I have port volumes.
I've calculted that I will need at least 220cfm @ .550 lift to make 500hp with this combination and I think I will have that much from the 308s. The exhaust port on the 308s is the same as the newer style magnums Flow numbers for the magnum exhaust seem to be around 160-170 and should be quit an improvement over the 915s I have worked with before.
