Ive restored a 70 (slant 6, now 340) and now I have a 71 Barracuda, former slant 6, now a 440
That being said, I had a thought: I'm thinking a orginal slant 6, 70 or 71 Cuda is rarer than a Big Block!
It just blows my mind slant 6's were an option in these cars, but straight 6s were available in Camaros, Chevelles, Novas, etc as well.............
