I found Terry to be an amazing workman with great craftsmanship.  The products and services you get with Hagedorn is surpassed by none other.  It’s pretty rare to actually get to talk to and communicate with the man building your motor, which is exactly the case with Terry Hagedorn.  He always welcomes my phone calls with questions, information seeking or simply asking for advice.  I personally appreciate Hagedorn Racing Engines, they are a great competitor and a great family to work with.
