That is not my question though, the assumption is that instead of having a 4.04 " bore the 340 core was given a 4.00" bore making the walls 4 hundredths thicker on this 360. So I was asking if anyone has heard of this. A am asking this with no knowledge on how a block is manufactured, meaning, do they cast a block with a smaller bore then machine it to the required bore? (in this case the a 360 could be made from a 340 core as long as originally the block was produced with a bore smaller than 4") Again, this is just something I was told, and I am just treating it a myth.
