what allows an engine to spin to 8,000+ rpms, and stay together for a long time

All of this and a dry sump is a must for spinning the motor that high!

i put a timing light on my motor, just to see how close the commanded timing (VIA HPtuners cable) is to the timing light.
just use a piston stop to find TDC on #1.
make a pointer from piece of piano wire, and put it under a front cover bolt.
mark the balancer/pulley... now you can only see the front edge of the line because of the belt... so put a little 90* turn down on the pointer, so you can read it from the front of the pulley easier..
then just use the timing light... it'll jump around, unless you use a tuning device to make it hold a constant advance. (just like disconnecting the timing wire on a stock thirdgen or other GM computer controlled HEI car)
BTW, not suprisingly, mine was dead on... even after a few thousand miles.. (meaning no pulley slip)
i cant say it was really useful, but i was bored.

I didnt have time to read through all the posts, but in case someone didnt mention the obvious (IMO) oil delivery will be a HUGE deal when you have an engine spinning that high. Id definately raise an eyebrow as to how youre gonna get oil to those higher ranges.
