on extension boxes
Looking for input on anyone who has put extension boxes on an panther hull. Has anyone gained anything off of putting them on and what kind of number are they getting from them? A scarab panther with twin 502s natural spray, 590 lift cams, dart heads with stainless marine hi-torque GEN III exhaust is the application that I have.
