Hypothetical scenario:

Take all the top end parts of a 680 HP / 600 torque 3.75-stroke combination with standard Victor heads.

Put them on a 500"-ish short block and keep the CR in pump gas territory... probably bump up the cam for the extra cubes.

What's the likely end result?

EDIT: I'm very happy with the my 3.75-stroke combination and it's a really good match for my car. I'm describing mine because it's a better example of what I was trying to ask than I think how most people understood my question.
