in 1970 you could get a t/a with the 440 six pack. How do I know I had one. Also my father work at Dodge Main from 1958 to it’s closing one of two plants that assemble them. At that time you could order any combination you want. This was also after Chrysler fill their obligations of so many 340 cars for the trans am racing. I’ve never seen a 1971. All this about hoods and shortages isn’t true. You ordered it you got it. My brother also had a 70 challenger with a 340 3 speed. There was no wrong or right. At that time if you work there. You could follow the car down the assembly line which my father did. We ordered our cars from Garity motors in hamtramack mich. got order numbers from dealer and time of build.
