My buddy had a 71 440 6pack Charger auto with 4.10 Dana.
I knew the car from new when a local teacher ordered and brought it home.

I remember the day in 1978 we took the original H-Pipe off the car and put it by the garbage, another friend happened by and was so glad he could have a free H-Pipe for his Cuda.

I think he cobbled it a bit since the Cuda had headers
