First 1967 383 installed in a Barracuda
My dad had a 67 fastback 383 4 speed car...
Someone cut him off when it was about 6 months old and he had to put it in the ditch to avoid hitting him and ended up totaling his car with only 6500 miles on it..
Luckily he was always a seat belt wearer and walked away from the accident with only bruises around his waist from the seat belt holding him back from going through the windshield... That reinforced him to always wear a seat belt, even before it became mandatory and they passed the law in the 80's...
Dad ended up replacing the Barracuda with a 68 Charger 383 2 bbl car...
