What is a good combo for turning high rpm?

I wanting to build a high rpm small block this winter for some scca road racing I've been doing over the past year. Anybody have any good proven engine combos that will turn to around 8k and be reliable? Or am I asking to much.

Any reason it has to spin to 8K rpm? I mean if you can make the same HP/TQ at 7K or 6.5K with a little bigger stroke you reliablity goes up a ton and your costs go down.
