12 Second Club - What do you think

I bought a 00' ws6 off here a couple of weeks ago. It has pacesetter L/T, magnaflow, 3.73, ls7 clutch, ls6 intake, ang a g5x2 cam. I went to the track at Beech bend tuesday and it ran a 12.64 @ 113. That was on sumitomo 315 street tires with a 2.0 60' and shifting it for all I could. Do you think that is a good time for my mods? I would like to have a big/little wheel combo with radials to improve my 60', what would you do next? The car is a dd and weighed in at 3670. Where is the closest place to Bowling Green KY for a good ls dyno tuner?
Thanks

For your weight, mods, and 60ft that isn't bad.

Go to http://www.dragtimes.com/da-density-altitude-calculator.php

You can look up the date time and track to get weather correction. If it was bad DA I bet your MPH corrects to over 115mph which isn't bad for cam only at your weight IMO.

That site shows a DA of 2001 which corrects it to a 12.34 @ 115.7. I don't understand corrected times and the DA and all of that but that is what it shows. I thought it it would probably pull a 12.3 on radials but the weather seemed fairly good and the most improvement I feel I will get is out of the 60' and 2nd gear spin unless I do a head change or add laughing gas, etc.

For sure, get your 60ft down to even a mediocre 1.7 and you will be bottom 12s.
