Mike - I think if you hunt around there are several versions of that dating back to the 70s. Moroso made the one I'm thinking of - but it was listed for circle track use IIRC and I'm not sure it's even available anymore. You can also fabricate something into the cover if you really feel the need. But unless you're running large clearances and high sustained rpm with G loading - you won't need it. Modern lubrication systems revolve around oil control, not limitless volume. So perfect clearances (not just in the bearings), scrapers, drainback, and the right pan are what you should spend money on. At least in my opinion.
