383 block w/ 440 parts ?

Member fisher built a 431 stroker with a 440 crank turned down and cut the counterweights 0.100" to fit the block.

I want to say with the Diamond flat tops Edelbrock heads and a lunati solid voodoo cam, pushed over 525hp....

REALLY ! mmm I was hoping to get around the high 400s w my 431ci.
