GOT GOOD TIRES!!!
Money spent on motor upgrades are good but without good rubber you are wasting your time going to the track. My stock 5.0L HO motor with only an Explorer intake and 70mm TB goes 14.0 at 97mph. I was launching it too low (3K) and shifting too high (5800) and still went 14.0. Launching hotter (5K) and shifting at 5200 will surely get me into the 13's. Look for a used set of 26x10.50 ET Streets or something similar......you'll be glad you did!
