If I were to blueprint, balance, use flat top pistos, port, polish and go with the bigger valves, use a four barrel with headers, and a better RVC cam, what can I be looking at power wise. I really don't care about HP and Torque ratings, I plan on putting this in either a roadster of a 50-54 Chev. I just want healthy, good cruising, desent power and a little inline bling instead of a sbc.
