rear gear affects on 1/4 mile

In the process of building a new motor for my 63 Nova , it currently has 3.90 gears in the rear end with a 26 inch tire . The motor is going to be super charged with close to 600 hp +/- . I already know its going to run out of gears with the 3.9s and about perfect would be 3.55s . How much affect on the 1/4 mile time would going to a little taller gear to make it a little more freeway freindly be , like going to a 3.00 ? I am estimating low 10s in the 130s mph
