Circa 1979,
Overhauled my Tiger's original 260, and had the machine work done at a shop
experienced in Fords and Tigers. Their 260-289 honcho warned me at the time
that if the block was worn beyond .030" that it couldn't be saved as it would
overheat if bored any higher. He said it would be cheaper to find a good 289
block in that case.
The job came in at .010" over and I was in business.

Circa 1976. I had a 64 Ford Falcon with a 260. I pulled the motor apart for
a "poorman's" rebuild (new bearing and rings) at 140,000 miles. The pistons
were already .040 over. I never had an overheating problem (if I could keep
the radiator from constantly blowing apart) on that second go-round at .040
over. This is just one man's experience. The wall thickness you have may
vary. I finally passed the car on at 175,000 miles. Tom Witt B9470101
