How much weight can you shave off of an A-Body...and still have it look/drive like an A-Body?

I had my all iron small block except intake 72 valiant down at 2900..in drag race mode…I would guess you could get another 200 out of it with a glass hood, aluminum engine components and lighter seats…add 50 to 75 back on if you’re looking for something with modern brakes and 18 inch wheels
