I had a '67 Satellite that was 3250# in race condition on the track scales. Small block, automatic, headers w/ no exhaust, 8.75 rear with a spool and gun drilled axles, Dragstar wheels, skinny front and 28x9 slicks, fiberglass hood, power steering, floor shift w/ console, full bucket seat interior, all exterior trim intact, 10 gallons of gas, and me at 180#.

Add 150# for the big block, 100# for the cast aluminum wheel/street tire combo, 50# for stock axles and Sure grip, and 50# for a steel hood you are at 3600. Increase it an extra bit for more gas, larger driver, or cast iron exhaust.
