Here are my weights. '70 Challenger, aluminum headed B stroker, 5 speed, AC, frame connectors & torque boxes, battery in trunk, full original style interior. Weight includes me, small tool box, full spare and jack:

Front 2,120 54%
Rear 1,849 46%
Total 3,960

I weighed at a local sand and gravel vendor accurate +/- 20 lbs. Lightening plans include 1) loose the "big Chrysler" alternator 2) Aluminum MC. Probably worth 25 lbs on the nose.
