No not maintenance.

So what repair do you believe to be needed for
ironblocks to achieve 300,000 miles?

If it was a 1950 Chevy, rings and bearings about 3 or 4 times. Oh, at
least one or 2 valve jobs too.

A '50 Chevy would have had an oil-trough spray
lube system, not fully pressurized, so one would
expect the bearings to die young. The engine
was basically a '20s design.

I'm thinking more of the many American cars sold
in the past 20 years that have gone over
300,000. I suspect that the real change there
is the lubricants--modern lubricants, especially
synthetics, are much much better than what was
available in the '50s.

I do know of two Toyota Celica that reached that mark. Engine ran great
but the body was pretty well rusted out. See through fenders for good
ventilation.

Then there was the Vega. I drove my brother's to California when he
moved cross country. It was never the same after that.
