Trying to understand how much I have under the hood...

I'm going to say 325-350. Which Holley 750?

I agree, depends a lot on compression and what your cam duration is at .50 inches of lift to get a better idea. This is all on paper though, your tune can make actual HP a lot less, a time slip with your MPH and weight will get you real #'s.
