The vast majority of oil consumption cases on the 350 were due to failure to seat piston rings at the factory, and then consumers taking it easy as directed. The 370 had similar oil consumption issues...likely the same cause.

You're not supposed to "take it easy"; you're supposed to avoid holding a constant engine speed...
Rev up and coast down should build vaccum and help seal the piston rings.
Zero oil consumption on any new motor I've broken in.
