So with those mods no N20 you are about with a stock RC, SB, 2wd 5.3L? I have seen a stock 07 classic 2wd RC, SB low 15's out in Ca.

16.8 with the stock 4.3 in phoenix.

16.7 with stock 4.8 and Corsa sport cat-back in hobbs, i think that night DA was 5200 and the a 2.6 60' is not helping the matters.

2 months until the track opens back up. Im hoping to have the 4.10's by then, so i can see what a Tuned LS6 Cammed 4.8, with Corsa Sport will run. I hope in the 15's. Might not sound impressive, but elevation kills all haha.
