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.

I have the twin to your brother's car in the Dart Lite family.
4 wheel small bolt pattern, 3 speed, manual steering and brakes.

Brown, with Parchment interior, 3 speed wipers, and Music Master AM radio.

I was under the impression that NO v8's were available, but you just never know.
