On MIR's digital scales my Challenger weighed 3755#s w/ me (210#s) and a 3/4 full tank of gas.

That's a full interior (except for the back seat) w/ rollbar, frame connectors, aluminum heads / intake / w-p housing, manual steering (saves almost 40#s over a power-steering setup), a complete 3" exhaust to the rear bumper, T/A-style fiberglass hood, and some misc. things removed (e.g. bumper reinforcement brackets).

Yep, it's heavy... which is why I nicknamed it the MoPig years ago.
