My buddies street duster with a 440, Pa sticker, cage, steel everything but hood, stock glass, heater, stock trunk annd wheel wells, inner fenders in the car, stock suspension with super stock springs, and 250 pound body was a hair under 3500.

All I can tell you is that is what it weigh when I drove it over the scale at the track. From what I remember my 70 Duster original 340 auto car weighed a tad over 3200 No cage or options . I know My orange 71 Duster was quite heavy. Add ons and all the options add up quick.
