I have a holley 800 9022 carb dart intake basically the same set-up as a mercruiser Hp 500 . I like to set the jets up the same as the Hp 500 carb with different size jets that they use. I spoke with mercruiser racing regarding this set-up they explained that using this intake theyt came up with the best results using these jets. Has anyone used this set-up with good results. Thanks Jeff
