I'm not trying to get into a pi$$ing match about this, but I know a lot about GM performance. I've been racing for over 25 years and have a 8 second Vette.
By the numbers, using well known information:
A stock C5/LS1/A4 puts down on avg 290 HP on a dynojet and traps ~107.
A stock, C5Z/LS6 puts down on avg 360 HP on a dynojet and traps ~116.
Therefore, how on gods earth is a stock long block LS1 with only Mani/TB/Gears/Stall/Tune and more parasitic DTL going to put down as much as a LS6/6speed on a dyno and trap higher when the whole world knows that autos trap less given the same HP level.
Explain to me and the rest of the world how you gained 70+HP and 15MPH with your mod list. It just doesn't add up. A friend of mine, who coincidentally was a C5 engineer under Dave McLellan also agrees with me.
