your opinions on stroker crank or grinding a factory

What's your HP goal ?
havnt really thought about a goal at this point. after i get a combo figured out, i will put some thought into what HP i would like. i know the internals are going to be a major factor into what HP/RPM the motor can handle. right now i am looking at 452 heads with some home porting. with better heads(i.e aftermarket ) the motor will be able to produce better numbers. so everything is up in the air, and im open to suggestions. what is a good HP estimate for a 451 with iron 452 heads?
