Re: 5 main durability

In the Packard 8 the difference is not so noticeable, but go back to the 3 vs 5 main bearing four cylinder motors and the difference is clearly audible. Noise generally indicates distress which is why virtually all fours today have five mains. However, that long crankshaft in the Packard is a delicate issue that takes a lot of energy to spin.
