ACC PUMP CAM HOLLEY SET

This AED 8 cam kit will allow you to tailor accelerator pump performance requirements on your Holley to the engines 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 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.
