<VV> Fwd: Cast Iron Rings Break-In

[Ken Pepke]

It was back in the 1930s when GM switched from cast iron rings to chrome rings.  Their intent was to improve compression pressure and oil control.  Corvairs never came from the factory without chrome rings.  Still, once the oil used in assembly is burned off there should be no noticeable smoke from the exhaust pipe[s], at least for a few miles, even with cast iron rings.
