All the dellorto's I have seen over the years only have it cast into the body but there are 2 main types. Early and late. A typical dellorto 40 will have DLHA40 cast into it and the late model will have an extra H at the end. DLHA40H. You want the earlier ones. They are much more suited to smaller ones than the later ones a the later carbs have slightly different progression ports that make it more difficult to tune down to your needs.
