12 Second Club - what should i run

98 trans am ram air,throttle body,subframe connector,borla catback,b and m shortthrow,comp t/a tires mossier 10bolt rearend stock gears .....1/4 mile time?

maybe a mid 13

If traction is decent I'd say 13.3-13.6

1st time out? If you know how to drive your car low 13s or 12.9 if you are really good, if not high 13s, low 14s. Plus track location is important (above or below sealevel)has a major effect on DA.

Mid 13's
