Shorter strokes shouldn't be the only consideration for building a high(er) rpm engine. For most people, valvetrain upgrades and increased airflow capacity will yeild higher overall rpm capability.
A couple examples:
The 427 inch LS7 has a 4.00" stroke and has a redline of 7100 rpm
the Ford GT 5.4L has a 4.165" stroke and has a redline of 6500 rpm
Both of these engines have relatively long strokes compared to their overall displacement.
As another example, a buddy of mine races a 65 Nova with a 468" BBC. It runs 9.60s in the 1/4 and crosses the line at 7100 rpm.
Just something to think about.
