Geeze, I didn't know that they could be that much heavy difference between the Dodges/Plys to the Chryslers.
Some cats here in Brooklyn had some extremely stout 68'-70' Buick Deuce and a quarter's that were giving mid size and small size cars the break. One particular Cadi convertible was totally gutted running its original 500 cubic inch mill on lots of mojo juice. Thing would lift the wheels at launch.

C-bodies, they carry the worlds weight.
