Remember the 289 Fords? They had an even shorter stroke, 2 7/8". There were a few round track guys who got the hot setup figured out on that engine, and on a short track they really got everybody's attention. It took some creative valve train work, but the 289's could live pretty happily at 8K+ RPM and stay together.
