I don't know the correct name for this item for a quad cam V8. The distributor fits into it and it holds it in place. The alloy thing in the end of the cam drive. Have a look at the pic and see what I mean http://www.1uzfe.com/031204e.jpg I only need 1 as I am going to use it to hold a HEI dizzy as I don't have all the original gear. Want a simple setup that I can tune. Dave
