Tailor pump shot to individual engines.
Includes 3 pump cams to fine-tune your Holley carb's accelerator pump shot.
This one will allow you to "tailor" accelerator pump performance to the engine's actual requirements.
Each cam has 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.
Kit includes cam #'s 218, 466 & 427
