Cobra Make, Engine: Owned CSX 3121 1969-1975. Went to the dark side and bought a 'Vette. May yet repent and be saved.

That was in the same era as the "stock" '64 GTO that ran 12 second quarters at 106 mph plus. Amazing what a massaged 421 inch motor can do for a goat.
Shelby pulled a similar trick with the 260 Cobra that was made available to the mags for testing. That engine somehow grew about 50 extra horsepower before it found its way into the car.
