Mexican Mopar 360: i need to know how to have more horsepowers

Where do you drive that you need to go that fast anyway?
The first thing i would do is to make sure the car is safe enough to go that speed.
This means tires, brakes, suspension, steering, and most importantly, body structure.
It looks to me as that the car is rusty, therefore weak, and therefore unsafe at any speed over 20 km/h..........
Let's see some more pictures of the car from all angles and the frames, torsion bar crossmember, etc.
