First order of business was swapping this vehicle over to a 6 speed manual transmission. This was the first known conversion to manual transmission in this body style Sierra. Using factory parts you can almost not even tell it came from the factory with an automatic transmission. Currenley the factory L83 is being built with forged internals and will be placed back into this vehicle with a Magnuson 2650 Supercharger. To dress it up, the front clip will be upgraded to 16-18 model year bumper and a 2500hd hood. Stay tuned to this project!
