Not Ranked
The 428 can do whatever the 427 can do. The length of stroke has nothing to do with how high it can rev, low end grunt, or how much hp it can make. Those are all common misconceptions and wives' tales. The only plus of the 427 is the oiling design and the bore size, which allows for larger valves without them being shrouded.
Otherwise, tell the 428 guys running NHRA SS that their engines can't turn 8000+ rpm and make 800 hp.
