I have owned my GT500 for 23 years. It has a 427 sideoiler with 482 cu. in. (4.25x4.25). It currently has a tunnelwedge with 660 holleys, although I have a NOS C7ZX intake with BJ/BK carbs for the purest. It has Shelby heads prepped and dyno'd by Keith Craft. Running gear consists of C6 trans with a 4.11 locker rearend. Best 1/4 mile time is 10.85 at 126 mph. Check out a video of a couple passes at the Texas Motorplex at
