Bell Hammer Seven is recommended for over-mileage vehicles to prevent engine vibration and to improve sealing of worn metal clearances using oil tension.
Bellhammer Lite has good pickup and gives a strong sense of thumping forward with light pressure on the gas pedal.
Bellhammer Lite is designed for light car engines, but it can be used for larger displacements without any problems. (This is a favorite among sports car users.)
