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...
Dad used to go 'GTO Hunting' in his 383 4-speed fastback...
There were a few young guys that had 389 GTO's around town... Dad would go on their route and meet up with them at the stop lights...
The GTO's were used to beating the first generation Barracudas because the biggest engine in them was the 273 4bbl commando... None of the GTO owners would look at the fender on his 67 and notice the 383 badge... The first light dad would be calm and cool and just idle while the GTO would rev his engine... The light would turn green and dad would beat them... (sleeper)...
The next light he would rev his engine back at the GTO... (The cat was out of the bag now)... The light would turn green and he'd beat them again... Third stop light and the rev contest and dad would blow them away again...
After that dad would turn left at the next light after beating them three out of three times... He proved who was better...
After about a week, the GTO's found another route and stayed off that one...
