Not really.. I got used to my car, the power band, and the sound, and I got so familiar with when the light would come on that I could make it just barely flicker on.. so I'm sure it was very close to 5800. Probably less than 5900 rpm

if you have new valve springs, you can shift a little higher. however, a bolt-on LT1 car does not make much more power any higher than 6000RPM. in fact, it starts to die off around there... unless you consider heads/cam a "bolt-on."

it sure does!
however, for those who who just put in new valve springs, and nothing more, don't expect to find any hidden power past 6000RPM. on a stock motor, TQ starts to drop after 3900, and the HP actually starts to drop after 5300. a good shift point on a stock motor would be right at 5250, where the HP and TQ meet, that way you shift back into the peak TQ band, and maintain the rise of the HP curve without it dropping off. that's where most people fall short, because the motor then begins to fall flat on it's face.
