Hey guys so I had recently bought a supposed hennessey venom 700 QC and the supercharger bearings went out on me on the drive home, so i took the truck to a shop and while getting it fixed I decided to have the supercharger, intake manifold, etc. to be polished, and I noticed on one of the supercharger brackets it said built and tuned by dave graves. Anyone know who he is? Or what shop he's from? Any kind of info would be appreciated because I honestly have no paperwork behind any of the mods and would love to have some.
