Good luck - my friend with a '94 Cobra hit 14.4s all nite his first time ever to the track this summer. 2.1 60s if I remember right. It was hot as balls.
I think his only mods were a short shifter and underdrives.
I'd bet 13s are well possible on the right night with the right driver.
Your launch is going to be the determining factor between 14s and 13s. Can't wait to hear how ya do, good luck man!
