Running the stock tank low on fuel is inviting fuel delivery problems. I like to keep my tank 7/8 full.
From practicality standpoint a 6 point bar will get you legal to 10.0 (for now). In my experience it's not that much harder to add the halo and forward bars and is very beneficial to chassis rigidity. If the car is a hotrod just do a S&W 14 point CM kit and be done with it.
If the 512 isn's fast enough hit it woth a 250 shot. No more complaints!
