My '67 fastback was 2920 with 440/727. I weighed about 180 at the time so 3100 race weight. Gutted interior, no cage, lowback poly seats, B&M Pro Stick. I later added 'glass body parts but never got around to weighing it with them, I would assume in the 2650 to 2700 range as a wild guess. The coupe I just bought will probably be lighter by at least hundred pounds even with a cage once I'm done.
I can't build a heavy car...OCD kicks in and I can't sleep at night if anything remains in the car that's unnecessary.
