Good thread,
following with interest.
You will probably find that your 202 will run a bit warmer than the 186 did, as they are basically the same engine block and share the same bore diameter, however the 202 has a quarter inch longer stroke, so in effect a bigger bang generating more heat.
As for the oversize/re-bored engines running hotter, i doubt it makes much difference until they are taken out a fair way, like sixty or eighty thou and by then cylinder walls are starting to get thinner.
Happy motoring.
Cheers, Mick.

interesting two old blokes bought my old 186 short motor and told me (not sure how accurate) that they had been in search of a holden 6 but insisted it had to be a std bore not oversized when questioned why, they said once reconditioned the oversize have heating problems which i find hard to believe given so many engines are rebored when reconditioned. Is there any truth to this. they were keen to measure the bore width which they did to confirm it was a std block not even trusting the piston stamp of 'std'. they did note the pistons on this engine had previously been changed - not sure how they knew that one.
anyhow good outcome, cleared up more room. thanks for watching.
