I had all the bolt-ons with the stock heads and cam. I was running a 14.6 at 94.8mph at the time. i added the e-brock intake 65mm TB, and shorty headers and my times dropped to a 14.3 at 97.2mph, I then added drag radials and a homemade CAI and it ran a 13.83 at 98.55mph. In a coupe it'd have been trapping ~100mph.
