1968 Barracuda fastback..formula S 383/4spd..Restore or not?

I picked up this 1968 Barracuda fastback with thoughts of building it into a race car but now i'm not sure I should go that route. Its originally a 383/4spd formula S. Although its been raped of more common parts, its still has the BB K frame,8-3/4 rear,clutch pedal and rear torque boxes. It has rot in floors, quarters and will need rear framerails. Amazingly,the trunk floor front rails are solid! I can do all the metal/body/mechanical work thats needed so labor isn't my issue. Besides all the missing parts, the car is missing the fender tag and build sheet. Does that make it unfeasible to do a restoration?
