I finally got around to taking the thing to the track. First run was terrible, 15.8@90mph. The car bogged like hell off the line, thank god I wasn't lined up with anyone. The next two runs were virtually identical, 14.86@92.94 was the faster of the two. The last run I was lined up against a 5.0 Mustang. He had an intake and an exhaust, but that wasn't enough to beat the 'Maro. I feel so much better now.
