I finally raced the only LS1 I hadn't lined up against since I got my stage IV finished. A black WS6 was in the left hand turn lane next to me. We both started our turn together, and 1/2 way through the turn he nailed it. I stuck with him until we completed the turn then walked past him on the straight, taking a 2 car lead through 2nd gear. We came up to another light, and he got pole position. There was a car in the other lane so I lined up behind him. He floored it off the line, spinning pretty bad. I got next to him and backed off, then we both hit it at 20 mph. I walked away comfortably, and he cut off early. I'm still waiting to find a modded LS1 to try, you would think there would be more of them around but most of the ones I've raced have been stock or close to stock.
