5 x 4 inch bolt circle wheels (absolutely numero uno). 13 inch wheels. 7 1/4 rear ends. Limited room for exhaust. Weak clutch once you start getting real horsepower.
64-5 Barracudas: parking lights staying on when headlights are turned on. I know that's common today, but back in the sixties it was extremely rare. Can't tell you how many cars would assume my parking lights were high beams and flash their lights at me. Then when I did turn on my high beams back at them, they were so weak they would just laugh and leave their brights on. Fixed that when I put driving lights on it I ordered from J.C. Whitney. Found out later they were aircraft landing lights. Nobody - and I mean NOBODY - argued with them.
