Rev limit?

I remember reading that the stock LS1 bottom end is good for 7,000rpm if you want to live brave. My F14 cam has a power band of 2,600-7,000. Right now I've got the rev limit set at 6,800 and it pulls to that very quickly.

With a good valve train, what is a good setting for rev limit for a 6spd street car?

[edit: can you move this to PCM-Programing?]

You know that just because a company says that doesn't mean that's where it'll rev, right?

What do you mean? I'm talking about where the rod bolts will safely hold together and where most motors with stock rocker arms have survived. I realize some motors may hang on while others grenade for no apparent reason. So, yes, I know I'm playing with fire, I plan on setting the normal driving rev limit at around 6,600, but when I dyno or maybe for a video clip or a run down 1320 I'd like to risk it and get that last bit of power out of it. Where do most builders feel that the stock 02 LS1 bottom ends will safely spin (on occasion).

So with PRC gold dual springs, titanium retainers, chromally and pushrods, where would you set your redline for testing and tuning...and then where would you set it for street driving and if someone else may drive your car?

I believe what he was trying to say is, if your cars power peaks prior to 7K theres no need to take that far if its already dropping by then. With my MS3 i make peak power around 6400-6500rpms, and i shift at 6700rpms right as the power begins to die down. Stock bottom end, i guess it all depends on the car. 2001-2002 had the stronger rod bolts, but that doesn't mean that it wont take a **** on you. Maybe the first time you take it to 7K it craps out, or maybe you take it to 7K for thousands of miles and nothing happens. I have seen guys post on here about taking it to 7K and never have a problem. If your making power way up there i say go for it, if not don't risk it and shift sooner.
