Is that a notch you drive? If so I don't have a problem beleiving that at all. 400lbs lighter than the rest. My car stock with exhaust has run a 9.0 at the 1/8 before and the ls1's usually run between 8.5-8.8 I think if I remember corectly, so with gears and little here's and theres I could definately see that. The LT1's run 8.9-9.3 stock and I watched the previous owner of my car stay dorr to door with an LT1. A GT or a vert would never do that though
Oh yeah finally one more thing... I had a 95 Formula LT1 AUTO and it ate the piss out of my buddies 93 6 Speed LT1. I've also heard it from others even before I experienced it myself... sooo that's saying something if it was an auto
