427 always makes more power than a 428 |

More torque too. Because of its bigger bore size the 427 can fill the cylinder more efficiently given everything else the same. For the same reason a 427 can have bigger valves thane a 428.
Nascar Ford racers of the 1960's could have run any bore / stroke combination under 7 litres. Guess which one they used?
