drove 4.6 01 GT not impressed

i had a 85 stang that i converted to a 89 lx look alike. Had aftermarket heads (vic jrs) edelbrock performer rpm intake edelbrock 750 cfm carb. headman long tube, hpipe (b/c in 85 it was a single pipe) flowmasters frpp 4.10's in a 8.8 rear 5spd. Anyway made tons of torque best time run 14.3 test drove 01 GT auto, at first impression my felt much faster b/c of the instant torque on the 5.0. Needless to say i needed a realiable car and took advantage of the 0.0% financing. End result stock trim with the 01 14.05 best run with auto. The difference in the power band messes with how fast the car feels.
As for the exhaust that was the first thing i ditched.
