I would recomend a dyno session and see were your power band is at. I really don't think you need to turn it so hard. The 6300 shifts is probably fine. There's no need to turn it way past your torque band the cars really not making time then.
I ams orry I mislead ya. I was thinking since it was a 346 cu in, and the cam was pretty good size for a small block that the 6500 rom shift point would be good. I was trying to also keep you from shifting into third rigth before the finish line and wasting time , as you lose just a little between shifts.
