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.\u003cbr\u003e\u003cbr\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":44624531489079,"sku":"HO20-81","price":91.1,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/86993.jpg?v=1780409221","url":"https:\/\/enginemaster.com.au\/products\/accelerator-pump-cam-kit-holley-4500-dominator-carburettors-kit-1","provider":"Engine Master","version":"1.0","type":"link"}
