1970-1973, 256 Engine, disc or drum brakes
1974-1979, 447 Engine, disc or drum brakes, mag or spoke wheels
1980-1983, 556? Engine, disc or drum brakes, mag or spoke wheels, TCI ignition
O.K., let me get started with my first "rube" question: This is the first I've seen of any reference to "256, 447 and 556" engines...what's up with that? I thought they were all identical except for carburetion on the later ones (and engine cosmetics. of course - is that it?).
TIA, guys...really appreciated. Looking forward to getting my new-to-me B model here to So Cal so I can get my ham-fists on it!
