I was just glancing at some of the costs for the fully machined aluminum blocks and thinking... does anybody subscribe to the old "seasoned block is better" line of thinking? At one time, many years ago, we used to think that an old block that had seen a number of heat cycles, that of course still passed all the tests, was better than a new block -- whether it be iron or aluminum. Now of course there is that weight thing.
But how is the feeling around here on old quality iron versus aluminum?
