As far as the original iron blocks go it's just easier and cheaper to locate a 428 crank than it is to locate a good 427 crank. The 428 crank has a longer stroke, which many prefer, and raises the cubes to around 450 cid.

Myself I would have prefered the original 'short stroke' 427 crank as it is better suited to high rpm and will 'build rpm' quicker than a 428 crank. But I don't turn my engine over 6400 rpm anyway, so 428 is fine and the added cubes are nice to have.

BIG bore, short stroke would be my ideal setup.
