Been wondering what my coupe would run, haven't had a chance to take it to the track yet. It's a 91 5.0 coupe with a world class T5, basically stock other than exhaust, cold air kit, underdrive pullies, throttle body. Estimates for 1/4 mile anyone? Also going to be swapping for some MT ET street's, and bbk equal lenth headers. Any extimates for before, and after tires/headers? Thanks guys.
