Default 92 mm FAST question

Everyone says the 92mm FAST will do better with more cubic inches. What about more RPMS ?? (A smaller engines way to create more air flow requirement)

If I went to a solid roller cam and decided to spin the hell out of this what issues do I have to look forward to?

The cost to build a motor to withstand over 7k revving would be far higher than going bigger cubes. Go to: www.rehermorrison.com & read Davids tips in tech-talk for details. Tip# 2

So I guess it will take a bit more then upgrading the main bearings. LOL. Thanks for the link.
