We have had the opportunity to work with Terry Hagedorn and Hagedorn Racing Engines for the past 4 years. During this time Terry has went above and beyond to ensure that we are always running great and ready to go. He is a phone call away if needed and has ventured to watch us hook. He is very committed and makes sure that we work with him on a personal basis so that we know exactly what is going on with our engine. Terry's camshaft and header technology is above and beyond anyone else.
