If it helps. My stripped and race ready 1970 Road Runner with light weight everything I could get my hands on. Fiberglass doors, fenders, hood, trunk lid, and Bumpers. Lexan for windows, aluminum dash, no interior, 10 point mild steel cage and, aluminum front hubs. Plastic seat aluminum heads, manifold, master cylinder, and radiator. Dana 60 with split mono leafs, Torsion bars in front and, stock K frame. 200Lbs driver and 5 gallons of fuel = 2850Lbs. I was hoping to get 9.?? out of it with a very healthy 500" stroker.
