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

Ez Equiel,
From what I can see, you will need to do 4 things to get to 200kph (about 120mph):
1. First (and muy imortante) make sure your car is safe to go that fast. Check the tires, check the suspension and check the brakes carefully. I would not want to be going 120mph with bad ball joints and or bad brakes.
2. Headers will help your engine breath and give you more power.
3. A high performance intake manifold will also help with power. And make sure the carburetor is working properly.
4. I would think that 3.23 (or something close to that) would be a good gear set for you.
