Those are great numbers Tony, should be a monster on the street. If you ever want to go drag racing all you need to do is swap in a bigger solid roller and put a single plane intake on it and you'll have 750 hp without any trouble.

The chart in my book says 525 cubic inches with MW ports will have a torque peak at 4900 rpm so it looks like you're right on the money. 1300 rpm spread between torque peak and hp peak is pretty good.

That engine would run low 10's in a 3200 car that you could cruise to the track in.
