My first 66 383 Belvedere II was 3750 with a half tank and a pair of slicks in the trunk. All steel wheels. My present 66 Belvedere I was 3370 when I got it with a /6 and working AC but I got it down to 2950 using a glass hood, no front bumper, most of the undercoating removed and rear seat, mats and rear window crap gone. I had also done some metal removal with a Greenlee hole punch kit. A buddies 72 Demon with the carpet and ac gone was 2950. It's a small block car with buckets and console auto car w/8 3/4, no undercoating.
