What is a good combo for turning high rpm?

Well I have found so far that the higher you can rev the engine road racing the less you have to shift. So to put it in perspective when I run road Atlanta there are 3 spots that if I could rev about 1k higher than my 6700 rev line I would totally eliminate a shift.
My budget is ~7k and I have a solid 318 roller motor right now

At 8K rpm would need close to $1K worth of valvetrain alone. Oiling is a big issue too at that rpm. What oil pan do you have? Better be a road race one with gates in it like these: http://www.milodon.com/oil-pans/road-race-oil-pans.asp

Are you using you existing block and parts as a start and a $7K budget after that? Maybe you need to list what you have to work with.

I'd talk with Tim Werner or AndyF about the shift point deal. The gain might not be what you expect. Or it may be. I don't know. But they would have a good idea. They just went from a 360 to a 427 stroker. Car went a lot faster at Portland Raceway.
