400 with 440 crank

anyone ever turn a 440`s rod throws down to big block chevy size, to run the chevy rods ? I still like the bigger cubes myself--------------

Think I would call that a 470.

Why even consider these things? The 451's are dogs. Was never able to get over 787HP out of mine with ported Edelbrock RPM heads, factory forged 3.75 crank and a single dominator on pump gas.
