assuming both are ~4" bore and 3.622 stroke? If so, 364 will have stronger cylinder walls.

Only marginally. Your crank would likely fail way before the .030 would make a difference.

I would trade the .5-1hp difference from the extra 6ci for the additional strength (even if its only a little) the any day of the week

My point was that if you have a 364 that doesn't need bored, then don't bore it. If you have a 370 in good shape, then don't go thru the trouble to try to find a new block.

You never specified iron or aluminum block. Typically if you see an engine advertised as a 364 or 365 it's an aluminum block LS2 at standard bore or .005" over. If you see a 370 it's usually an iron block becuase most builders bore them .030" over. This might not always be the situation but is what i've seen looking around at various companies.

^^^this, if its a 370 iron block, id go for that. For obvious reasons, it will be stronger, but will be heavier as well.
