Depending on miles on the engine it could be very different. But lets assume you have decent compression, 318 stock made about 150hp so there is alot of improvement that can be made. id make a guess at about 220-240hp at the crank or around 200 at the rear wheels. Before a cam get a different intake manifold, if it cant breath then there wont be much HP. The cam selection all depends on what you wanna do with it? street? strip? daily driver?

This is either a marketing hype by some cam manufacturer, and it might just be Crower or it's possible the owner doesn't even know, maybe just heard it somewhere
The old "max wedge" 426 engines were sometimes referred to as "stage 3" and these were "as delivered" by Mopar, not by some hot rod shop
If he can't tell you SPECIFICALLY what cam is in the engine, then he doesn't know much. He should be able to say "Crower, Sig Erson, Racer Brown," whatever it might be, and tell you what it IS.
I can assure you that if you waltzed into a Chrysler dealer, and said something like "I need the specs on my stage II cam, the old fart behind the counter would look up with that bored look, and say, "huh?"

440roadrunner is right. Stage 2 is not a very good term to use when you are describing your cam. There are many lifts, durations and lobe seperations that could fit in this term. My advice to you is not to use this term because 1. It makes you look stupid and 2. Its not detailed enough.

Hey Guys
The engine is just an air pump with controled explosions inside. The longer the valve is open (duration), the wider it opens (lift) the more over lap (more radical or the time both the intake and exhaust are open at the same time)- (overlap) the better charge you get in the cylinder. With a better charge in the cylingder the more force on the pistom and more power.
There's a lot of terms used that are pure marketing. No scientific basis at all.
The fellows not stuipid, he's just learning, and the term Stage this or that was and is still used by a lot of aftermarket people.
Life is a learning thing, there's always more to learn.
