What do you guys think id dyno on my 98 with mods in sig?

Also what do you think id run in the 1/4mile at cecil county dragway

Hoping to pull 12's in good air at the end of october in the morning.. DA's get into the -1000+.. What do you guys think? also what should my next mod be

 

Lid, catback, and LS6 intake. Stock torque converter?

0' DA should put you in the 12.8s or there abouts IF you have traction.

 

yeah stock torque converter.. The previous owner told me he went 12.7 at cecil... and that was minus the LS6 but I wasnt sure to believe him considering a catback and a lid thats pretty quick.. Also i was going to add longtubes and tune if i did that id be dissapointed if i didnt run under 12.5
