One could build a bored/stroked 7000 RPM S65 with 400 hp, but that would be seen as a big waste of money and a step backward by most. Similarly one could build a destroked 8400 RPM S62 with 414 hp but that would be seen as a waste of resources as well.

For racing applications, either engine is capable of 600hp+ once you equalize displacement and RPM. The S62 may have a higher deck (not sure) which would mean more displacement potential in theory. Both have an 98mm bore center like all BMW V8s. For a race series that does not allow altering the short block from stock, the S62 obviously has the advantage.

S62 : 348lbs
