Looks to be R4 red.
All Dart Lites and Feather Dusters were 833 O.Ds I believe.
Cool project ! I think if built and tuned correctly 30+ mpg is attainable.
Nope. My dad's was a 3 speed on the floor. 76 feather duster. That car still pisses me off was supposed to be my first car
Dad bought it as a work car a few years before I got my license... But my brother who is older wrecked his 74 charger and needed a car like "right now" so I the feather became his.
