476rwhp on Stock Block
I had a huge scare during a 5th gear pull, lol…ran 4th gear to redline, spent several seconds pulling in 5th gear, then all of a sudden the car detonated, I let off the throttle and is sounded like the engine was coming apart, tiny pieces just breaking off… I pictured a catastrophic engine failure, my heart sank, I started to break into a cold sweat. Well, I pulled over and found the front splash guard came apart and was just getting minced by the tire, lol…pulled it off and started boosting away again. 
But good luck OP, I’m curious to see how your stock engine holds up; I’ve got to up the boost on my car now.

I would be more concerned with low gear acceleration with all that torque down low, over high speed runs. Even in 3rd if you hit it at 3000rpm, the stress on the rods will be much higher than a top speed run do to the torque. This of course applies if you have good rubber with good grip.
High gear pulls are worse than low. The engine is under load far longer in this situation and as someone already mentioned, temps go up. The engine produces the same amount of torque whether in 1st gear or 6th gear; the drivetrain changes the amount of torque at the wheels.
Grippy tires don't affect rods; those affect other drivetrain components such as axles. I believe the torque you are referring to is the torque at the wheels rather than the torque at the rods.
From my understanding:

Good numbers. I am making 473whp@10.5psi with a JWT 700 kit and meth on a stock block as well. It has held together with 1/4mile runs and some longer pulls in the higher gears. But just could be a matter of time as well. Going up to 13-14psi in the spring to try it out.

nice power.
i made 467rwhp dynojet SAE at 9 psi on my stock block in 2004. At STD setting, it would be probably the same exact number you are at. Raised rev limiter to 7000.
I took the car out street racing literally every night for a couple seasons. Ran it very hard, banging on the speed limiter at least once a night. Running on the drag radials from a stop or roll races on the 19s. I beat the living **** out of that poor engine.
When I tore it down to do a build, the internals were mint. The bearings looked brand new too.
Keep the tune good and dont starve fuel pressure running a low tank around a hard right and then full throttle... and it should be pretty difficult to blow it up. its all in the tune.

And my rev limit is at 7k and thats where a shift, but in 5th gear on the dyno i just didn't want to risk it
nice numbers but i got a good laugh out of the tune being reserved for c6 and built tt z's. z06 c6 puts out 515hp, you still wo'nt touch it along with a built TT z. They will be tuned for a lot higher than 476. No reason to blow your car up on a race you know youre already going to lose.

I just went on a Zo6 forum the one dyno 450whp stock he did 479 with K&N headers and a tune another I found did 470whp stock so he is in the same ball park power wise however they are alot lighter and torquey. I race cars that should beat me all of the time, just because they have more power doesn't mean they can drive
I smoked a Shelby GT500 when i had 400whp he had a 1,000,000 excuses.....but he still saw nothing but tail lights.

Duh people, the tq from the v8 and INSTANT power will make the vette win every time. Just go against an auto and all he has to do is push down teh pedal and walk away.
Op is obviously talking about street racing and not drag strip so you can't really argue about "racing skills".
Shouldn't race if you can't win......wow I bet you guys have fun racing sunfires. I want to race cars that win or lose they gave me a good run. I guess maybe not everyone is that competitive though and get a rush from racing sure things.

Nice number by the way.
