blueprinting small block oil pump

I raced in rallies a long time, where you can put a lot of sustained revs on engines, and once I learned, found that pumps could be restored to very good condition with new gears and new a cover, or a new body if it was worn. Nothing fancy needed, just go back to the new clearances. So I don't subscribe to the coated gears and such being necessary for most engine hot-rodding.

I eventually got to just replacing the pump at every rebuild; cheap insurance. Never had an oiling related issues once I adopted those basic practices, and bearings always looked good at a teardown. Running 1 HP per ci to 1.75 HP per ci turbo'd.
