Guest Posted July 18, 2000 Share Posted July 18, 2000 i just bought a 72 centurion with a 455 motor. i suspect that it is fairly tall geared since it is an animal on the highway. What exactly will my axle ratio be? It is the fastest car i have ever driven but the problem is, is that it weighs 4300 lbs. Anything i can do to easily boost my horsepower into the 300's?
