do as many block oil mods as you feel comfortable with/blueprint the pump/alot of passage deburring (it is needed). that way your foundation is solid & the correct selection of add ons will give you what you want with the solid foundation in place (oiling/cooling etc). You might peruse Sanborns oiling/cooling mods that are in a sticky at www.moparchat then scroll down to & click on "circle track chat". SB stuff but alot is relevent for a BB. (long read but worth it).
