Cam Assortment

Kit
Holley accelerator pump cams will allow you to "tailor" accelerator pump performance to your engine's actual requirements.
They include cams that have a different shape or profile to give different results.
Cam "lift" directly affects the accelerator pump stroke, and, therefore, pump capacity.
Ramp profile or shape controls the "timing" of the shot.
A steeply-rising ramp shape will give a fast, heavy fuel shot right off idle.
Conversely, a gently sloping ramp will spread the pump action over a longer period of time.
