First 1967 383 installed in a Barracuda
The production for the 1967 Barracuda started in November 1966, I suspect that the magazine cars were pre production engineering cars or some sort of pre production test car.
My grandfather purchased his 67 Barracuda the first week of December 1966, he asked about the 383 but when they said no power steering he was out. Was the car available then? I have no idea.
