I lightened my car by removing a/c, fender weight, vert top motor, 4 heavy cats, dogbone, aluminum heads, smog, vert cross brace, abags..altogether that amounts to about 250#..add 50# for 414 with a starting weight of 3450 and you get about 3250#. It is a vert and I still could remove rear seats and spare to take it down to 3180# and there's still more but then you are getting into more of a track car than street.
