The specifications for the I5 are at
Plastigage is your friend - it's so easy to use.
I'd add a further note of caution - even on an engine that you know has never been stripped,
never assume the crank bearings are a standad size. ALWAYS read the markings.
I saw one case a few years back of a single owner car that had some bore damage. Whipped it
out, rebored a couple of cylinders, fitted a couple of oversize pistons and rebuilt.
Naturally if you're going to these lengths, new shells make sense. The engine ran well, but
there was a strange fluttering noise when it was decellerating after a throttle blip. Checked
the removed shells and found the big ends were oversize - the factory had fitted a reground
crank. The mains were standard size.
When I mentioned this a few years ago, several people said they'd seen such engines.
