What is a good combo for turning high rpm?

OK, I just got to say that if your pals running the LS motors are full of it. No way their 10,000 rpm motors only cost 7 large. I'm building two LS9 cars for customers right now and just finished a LSX supercharged car for another. The LSX car was good for 800hp and could probably stay bolted togeether at 10k. I wasn't ballsy enough to try that. Even without the huffer on it, it was way above that magic 7 number.

So even if you could build your LS based motor for that amount of money, how much will it cost to transplant it into your Demon? You could add that amount into your Mopar build.....
