) at the time to buy DR's or E/T Streets, so my traction suffered really bad off the line
. Also, the gears whined really bad, so I just took the gears back replaced the factory 2.73's at the time. I've currently got another rear end that I'm going to put in the car this summer, and I'm going to invest in TIRES this year as well

Just FWIW, my car ran the exact same time and speed as listed in my sig even with 3.73's, as compared to with 2.73's
............so if you're running .2 seconds faster than me, 108 - 109 mph sounds more realistic than ~117 anyways

your car may also have a speed limiter that came on non high speed tire equipped fbodys that shuts down your car like a rev limiter at 109 mine has that on it but you can get it programmed out just a thought
