HPP (Heide Performance Products) is one of the best custom shops period and the quality of his work is amazing. He does alot of work for the OEM's and was very instrumental in the development of the Mopar 10 and the 200 Super S Concept for Chrysler. I have worked on a few projects with Gordon Heidacker and his guys and will absolutely vouch for him on anything. He is currently building us 2 more Daytona Challengers and the #1 Richard Petty Signature Series Superbird. We are also working on a 2011 Dodge Charger SEMA car.
