1976 Feather Duster comes with 383

my brother had a Feather Duster; 4-wheel drum (early 76 model, built during '75, all cars built starting 1/1/76 were mandated for front discs) 3 speed on the floor manual brakes and steering,
I had heard that some FD's and their "partners" from Dodge, the "Dart Lite" came with 318s too. but I have never seen one. Stock, anyway.
