I am trying to decide what I want to do with a 1967 mustang fastback. I am thinking of an authentic Shelby Gt 350 clone car. I can't find how and maybe it is not possible, to convert a 289 to replicate the shelby motor. Can any of you vets educate me and how to best do this. I know this is a bit of a broad post but I want to determine if this idea can be done and the always painful question, can I afford this idea? Thanks for your thoughts.
