your opinions on stroker crank or grinding a factory

If you are going to go through the work to grind a 440 crank, might as well offset grind it to a BB Chevy journal at 3.90-3.915 stroke = 470" The 3.75 crank set up works awesome as well.

Last time I checked on that type of work around here in CA, it was in the 400-450 range.

Counterweights need cutting along with main journals.
