Yeah, I know from experience that a WS6 will take a Sy. A friend and I raced down here in FL. I had my brother and a friend in my WS6, the 3 of us totalling about 600 lbs, and it was pretty even until I started to get to the top of second and was slowly creeping away. I believe he also had a bad launch, at least that's what he said, heh heh. That was also with a little over 700 miles on the car, they say after about 4-5000 it will really open up, strange. With my Ty nearing the end of a parts list I can't wait to start ripping into the ls1. Best part is that you get a really warm and fuzzy with a car that runs mid 13's and still gets 30 mpg on the hwy.
