Quarter mile time attainability?

Okay, so the car in my signature is getting a fresh short block this next month. Just a pretty standard 302. I am going to have the heads rebuilt, and them put the motor back together, same cam, and everything. The motor has about 105K, is the reason for this, but the blower and cam are only about 10K old. I plan on installing 30/LB injectors, a larger TB and MAF as they are both stock. Iwth a good tune i am hoping for 350RWHP, the car has already dyno'd 333, with 8lbs of boost. I am considering stepping down to 6lbs, for longevity and drivability. But enough of that, is a 12.5 quarter a realistic goal with this setup? Or am i dreaming. Now, i am expecting something like this my first time down the track, but eventually would be nice.
 
My cousin went 13.2 at 106 with a KB blowzilla pulleyed for 6lbs of boost, stocks heads and cam, so with more boost and better flowing heads mid-high 12's should be attainable IF you can maintain traction.
 
Having driven a few KB cars, I know traction will be your biggest hurdle, and without either DR's or slicks, I can almost guarantee you that you will not hit even high 12's. My cousin's run was on 245-50-16 nitto DR's.
