RE: consequences of overreving?
Since we don't have interference engines, there's not as much danger from overrevving, floating the valves, and ramming them into the cylinder heads. The MOD V8's are actually quite revvy and to be honest, I wouldn't really start worrying until you're well into 7000rpms. And then, I'd just get a better oil pump and stronger valve springs.

When I was on the bone stock longblock, I shifted at 6800 rpm and never had an issue.

American muscle hasn't seen an interference engine in a LONG time...lol
But here's a decent article describing the difference of using a rubber timing belt...

mine is set to 6500. I hit it all the time LOL but I think it's just common sense thathittinghigh RPMon a regular basiswill eventually wear the engine down quicker.

RE: consequences of overreving?
With an interference engine, the valves will protrude further into the cylinder chamber allowing less resistance for the flow of intake and exhaust gases. On the other hand, timing becomes difficult. Poor timing, valve float, over-revving could all lead to the valves impacting the cylinder heads. Bent valves are not really good for that whole performance thing.
Though not all interference engines use belts. For example, the S2000's 2.0l I4 is an interference engine and has a timing chain. What an engine...

RE: consequences of overreving?
ISN'T IT TRUE THOUGH THAT WITH A STOCK GT THE MAX HORSEPOWER AND TORQUE TOPS OUT AT AROUND 5800 RPMS? I WAS ALWAYS UNDER THE ASSUMPTION THAT IT DOESN'T DO ANYTHING FOR YOU TO HIT RED LINE...OR SURPASS IT FOR THAT MATTER. WITH MY CAR I COULD NEVER EVER SEE MYSELF GOING OVER 6000 EVER. WHY SPEND $25,000-$30,000 ON A CAR AND BEAT THE HELL OUT OF THE MOTOR? MAYBE I'M JUST VERY CONSERVATIVE, BUT IN MY OPINION THE REDLINE IS THERE FOR A REASON. 5800 IS JUST FINE FOR ME.

Also, why would a person buy a car touting performance if they're not going to use that performace?
"Hey man, nice 'Vette... HOLY **** its a Z06!"
"Why thank you!"
"Been to the track yet?"
"No no no. We've done a couple parades and I push it out of the garage every weekend to clean it."
