    Sorry postwhoring now but .030 doesn't add 30 cubes to the motor.You have to use the BorexStroke formula to get the real figure.

    331 is a .030" over 302, with a 3.25" stroker crank. Or a 327 if it's standard bore...

    Formula.....

    Bore Radius^2 * 3.14 (Pi) * Stroke * # of cylinders = Internal Displacement

    You didn't increase the stroke of the crankshaft, you just enlarged the cylinder bores.

    no, in order to get like 30 cubes you would have needed to stroke it. A 30 over is actually .030 and like was said earlier it isnt a substantial amount. Although your logic is almost sound as most people will say "30 over", I have seen many people newer to motors come to the same conclusion, infact theres a craigslist ad I just looked at that said the same thing.
