mods are 2500 stall,edelbrock headers w/ory, bypassed t/b, cai, flowmaster 3inch full catback..transgo shift kit.and getting drag radials..my stock dyno put down 243 and 285 woth cheap gas and a missfire..i still have stock 273 gears..i want to be able to pull 13's..i beat my brothers 95 gt that ran 14.4's..and passed him like nothin..and raced my twins 99gt and hang/might pull on him which he ran 14.0's bone stock and now has mods and 410's..so with d.r i want to be in 13's

 

13's with a decent run. ditch the 2.73's and you'll see mid 13's.

 

Yep, you should have a mid 13sec car there once you get some 3.73 or deeper gears especially with the stall.
