Since this thread has had some new life breathed into it, I wanted to throw a little info out there about the perceived oiling issues. In short the 460 has a very good factory oils system with the mains fed from a large gallery of passenger side lifters. It is as good (if not better) as any factory wet sump system out there. With that said there are things that can be improved if you’re looking for big RPM and high cornering loads. IMO, the first area should be pan volume. The more
oil you have in the pan, the longer the pump can run before it sucks air. I like a full length, “T” sump pan with a rear pickup and make sure your
oil level is full! Use all the capacity you have. I think it behooves everyone to take windage and baffeling seriously if you plan to spin a motor past 6000 rpm. It is a hurricane inside the crankcase over 6k rpm. Anything you can do to keep the pick-up covered is a good thing. A solid (louvered) windage tray and trap doors, gates are a real benefit. The next area would be
oil retention in the heads. All of the oil to the heads is returned via two ¼ drain holes. These holes can (and should) be opened up to 3/8 or 7/16 dia. Lastly would be the volume of oil moving up to the heads. Only If really necessary would I consider restricting the oil to the heads.
An Accusump is a good, simple and relatively inexpensive insurance policy. I have one and I like it very much. It is also nice to see good solid oil pressure before you turn the key.
Just my .02
