A Bodies are heavy? Hah
Well, stock and fully operational cars can varry a good bit depending on Year, engine and equipment installed. My '73 /6 had on the Reggie 2860lbs.
It had 4 wheel power drum brakes, P/S, and A/C.
I later installed a 8-1/4 vs the 7-1/4 along with a 318/904. I removed the iron intake and exhaust manifolds for a aluminum intake and headers. Also removed the bench for light weight buckets. Close to a break even.
