this is the only video i have, this was all stock with a cone filter. that Z28 has ran a best of 13.2 at 103, and the M3 has full exhaust, intake and a tune.

I just watched the video. I am still doubtful about a run against a stock ls1. You ran an lt1 that trapped a best of 103 mph. Stock ls1s can track 106-108. That is quite a difference. E36 M3s aren't particularly fast either.

Pro FWD -- 1. Marty Ladwig, Chevrolet Cobalt, 7.659, 197.54 vs. 2. Jason Hunt, Saturn Ion, 7.878, 191.28.
"Running back-to-back 197 mph passes not only shows how consistent the Ecotec engine is, but also how fast the track is. They’ve done a great job resurfacing the track here (at Atco). We’ll see if we can go even faster tomorrow.”

Don't take this as I am not saying it didn't happen though. I would like to eventually take a ride in a Cobalt SS, just to see what some of the fuss is about.
