Is a '69 AMX considered a mopar A-body?

Unless someone swapped in a mopar 360 in, it's probably an AMC 360.

The AMC 390 is also very different than a Ford 390. It most likely had an AMC 390

See. I learned something new in 5 min. But the 360 distributor is in Mopar 360 location. Was AMC the same?
