This car has been sort of a development car for us, we have been doing c7's and the new di trucks for years now and are very well known in those group's for producing high hp reliable LTX vehicles. We hold a few records w/ our C7 builds and truck builds actually.
Next this car comes back for one of our custom cam's, 15'' wheel conversion, and going after the stock bottom end 1/4 mile record. Any questions on the setup or if you're looking at getting any of these parts please feel free to email, pm, or call me at the shop.
