Some 5th gen 1LEs dynoed right around 400 +- depending on the dyno. Dynos do not mean much unless you compare runs on the same day, same car, same dyno. But still cool to see one of the first.

Manual 5th gens can be compared to manual Ca6 SSes. So a little more power and a 200 pound loss means about .5 second ET improvement. Most of that comes from the weight loss.
The best LS3 5th gen stock run (and a hero run at that) is 12.588. Will we see a CA6 SS manual in the 11s stock? That would be cool. Comparing auto 8s is not a fair comparison for the M6es. They should more easily hit the 11s. We shall see. The CA6 SS is a fast car. Nice to see they no longer fear 5.0s or 392 Mopars. The tables have turned.
