My '73 Challenger w/ me on digi-scales was 3755 #s
- full OEM interior, except back seat
- 8-point rollbar
- OEM RB block
- glass T/A replica hood
- 8.75" diff
- only 1/4 tank of fuel when weighed
- driver probably 185 at the time, so car was about 3570

When it comes back out, it's going to be heavier, regardless
- Victor heads feel like 10 #s more each than Stage VIs
- swapped 8.75" for Strange S-60... 40+ #s?
- driver about 210 #s now
- and at 6 #s per gallon of fuel, an easy 70 #s for closer to a full tank

Add an est. 130 #s w/o driver and I'd expect 3700 #s for car -- assuming full tank -- and 3900+ w/ driver.

Nope, NOT light.
