My 70 dart thinks she's fat.

Hey guys & gals, I'm getting ready to build a 471 stroker for my 70 swinger.
I plan on boogeying in her, I will be using a lift off six pack hood, front bumper & valance since my valance & bumper are crappy. Since this isn't a numbers matching rare car I'd like to know what non-structural weight (steel) can be removed by my new plasma cutter? I'd like to be at 2700 lbs.
If anyone is familiar with Tony from uncle Tony's garage on YouTube his dart is around 2500 pounds but a slant 6 .
