Whats The Maximum Horsepower Im Going To Get Out Of A Pontiac Lemans 400 Ci Engine

To all the gear heads who know alot about muscle cars what is the maximum horsepower i can get out of a 78 lemans v8 400 ci? i already have the 400 ci turbo trans with a shift kit on it but i havent made the effort to change the rear end to positive traction and put the gears and either a 9 or ten bolt on? what is somethings i can do to increase power comming from the engine without putting a blower on or supercharging it if thats possible? should i put new pistons and headers on or that doesnt really matter?
