Default 8.000? 10.000?

Hi, well- I've been dreaming of a 10.000 rpm 302 for some years, and here are my thoughts on this matter:

- Sturdy 4- bolt block
- Standard throw crank, lightened, knife- edged, polished... (stroking WILL lower the RPM potential)
- Light weight long rods (I- beam of a special kind.?.)
- Short- skirt pistons of some kind. Bore= 4.125? or std (keeps weight down).
- Belt- drive cam gear.
- Heads: high- ported head. Canted valves?
- Solid roller cam- no doubt.
- Roller bearings for the cam.
- Light weight lifters.
- titanium valves, keepers and retainers.
- shaft mounted rocker arms
- dry sump system w/ scraper etc
- tuned headers, "snake-pit" like the GT40

For a 8000 rpm 331/347 (which I curently use, well- ok, let's say 7500)- assuming you use a well balanced stroker kit (like "Eagle competition" or equivalent consisting of "goodenuff" parts) I think you can make the engine reliable by using:
- A "priority" oiling system, for instance by using the rollers for the cam. Has to be well- designed anyway.
- A professional balancing of the rotating assembly- if the engine will be running at 7000 rpm+ continously, the workshop should take that in consideration.
- A light weight valvetrain including a solid roller cam......
(-A professional assembly of the engine, of course.)

Any comments?
