Shift it at 5000rpm if not already doing so...buzzing that motor kills et. Your car will run a 13.00 in decent air with a 3.73 gear and the stock converter.
My '99 Z-28 was campaigned in NMCA in 2000. The only modifications were a shift kit, HyperTech tuner, 4.10 gear and M/T DOT tires...ran a best of 12.78 at Moroso Park in good air. Began running the 13-second index efi class at the beginning of the year...by year end I had installed a 125 shot dry nitrous kit with a progressive controller and dropped down to efi 12. It ran a best of 11.66 @ 118mph.

I hope to be getting my car dynotuned this week after adding LT's, BH True Duals, LS6 intake, ported TB, SSRA, plugs/wiresAre. Are you suggesting that I have my tuner make the shift point at 5K? I'm fairly new here but I think my tuner would laugh at me. My car shifts around 5800-6K. I plan to keep it around that. Staging Lane

This past spring I rebuilt my transmission and tightened up band clearance quit a bit in turn causing it to short shift from my original tune settings.
It would shift 1-2 at 5500. Ran 12.4@108 with it short shifting. Had my tuner make a adjustment and got it squared away. The next weekend shifting at 6150 on the 1-2 it ran 12.2@111 mph in exact same weather

This is based on a assumed factory torque converter and minimal mods. You can let the car make the shift decisions or you can take control and actually drive it yourself. Just letting you know what works. Btw, shifting by a tach at 5000 will usually produce 5500 or higher rpm shifts due to reaction by the driver...point being the engine wants/needs a lower shift point for maximum et reduction. My honest opinion atm is to have a set of DOT radials for the rear before anything else.

For a truly stock car, you are correct. And I have to say, the car in this thread is close enough. Unless you swap the camshaft and/or intake manifold, a stock ls1 camaro peaks between 5000 and 5500 and begins to taper down after that.
Above is a truly stock ls1 camaro dyno graph.

I'm a noob, but it defies logic to me too. My issue in believing this logic has to do with what the RPM will be after the shift. It will be to an even lower portion of the power curve. This is in addition to not taking advantage of more time in the peak power.

The car will tell you what it wants based on the et slip.

So, to shift an Auto at 5K manually, you start in 1st and shift into each gear at 5K which will be close to 5500 by the time it shifts. Is that how it works? Heck I'd be willing to try it myself at the track next time. Assuming I get my car tuned this week, I plan to make it to the strip within the next few weeks to get some feedback about the gains from my mods.
