12.9s on a stock motor... with gears, shifter, and full exhaust. But a 98 with a 01 block or something. The best I've seen in a Cobra is 13.3 @ 10x, something MM&FF did. The best I've seen at the track is a 13.6 @ 102.
12.9s is a big jump from the mid 13s they've been getting.
But if the LS1 can do it, I would bet that a 4v can do it... with a solid rear axle.
