420 to 430... But dyno's are all over the place on what they will spit out... trap speed tells the honest story every time. Did you put the new intake on it?
The FAST 90/90 intake is on now but the 11.82 @ 121.8 was with the ls6 intake.

I actually hooked up pretty well on the street tires so I don't think wheel spin was a cause for the increased mph. The 60' was a 1.88 walking it out from 1700 rpms.
The only times I've seen mph increase with wheel spin is when there is just enough spin to get you in your powerband sooner. Frying the tires will not increase your mph.
