For the current mods, this vehicle is bone stock for the most part. It does include a few extra goodies that we mention below:

Before we make the dyno pull with 93 Octane Fuel in the tank. It is equipped with 3.27 rear end gears with the Factory engine and T5 Transmission. The World Class T5 Transmission will be in 4th gear for the pull due to this being the 1:1 ratio with the timing being set to 14 degrees. Let's make the pull!
