You would need some VERY lightweight and NEAR PERFECT machining and tolerances as well as very little imbalance to be able to rev a 302 that high "reliably". I suppose you could invest in a rotary valve cylinder head and get a well put together bottom end for around $5000 for just the main parts, but you'd have to machine and balance everything yourself. Chances are unless you get parts for free, you'd go over the 5,000 dollar budget pretty quick. There's alot of inertia and rotating mass forces going on at 10,000 rpm. I can't see it being done for $5,000. Now 8,000 rpm possibly, but not 10,000
