I was very surprised when I weighed my son's 73 Scamp. Quarter tank of fuel, full interior, all steel and glass, 6.1 Hemi, 904, 8 3/4. 3140 lbs. I would've thought closer to 3400.
2-door Scamps and Valiants, are likely the lightest of the post-1967 A-bodies. and
67>69 Barracuda fastbacks are about the heaviest.
Well, maybe not including the 318 Swinger fat-boys, loaded up with everything in the catalog.
