Flat valley pan, meaning the PCV valve is seeing direct oil splash.

Stock baffled or equivalent Tomahawk valley pan would be the first thing I’d change to solve the oil consumption.

Flat valley pans are for race engines as far as I’m concerned.

Could be some crud holding the oil pump check ball off of its seat, I’d check that. Or perhaps your bearing clearance isn’t tight enough.
