Ron, I split the difference and went with the wet pan, external
oil pump. Did not want to route the hoses all the way to the trunk for the
oil tank and use 3 gallons of
oil at oil change. Using it on a 520cid aluminum engine. Perfect after 1000 miles. Used Avaid pump, which I think is made by Peterson and Jeff Johnson billitt pan. Don't know what your motivation is to use this set up, but mine was to get rid of the cam gear wear problem. Went one step further and used electromotive Tec 3 ignition, so now nothing drives off the cam.
