Dan et al.,
This reminds me of a happening at a NASCAR event last summer. According to
an ESPN report, officials had so and so's engine pulled down immediately
after a race and found the cylinder bore to be over the limit. Reportedly,
the driver's pit chief asked for a re-measurement after the engine cooled
down a bit, and guess what? The bore was in spec and was declared legal
after all.
