Okay gentlemen - I spoke directly with the guy at Adsit who is working on my long block. I politely relayed concerns about the quality and particularly the customer service at Adsit and advised him that this was not fun hobby or project car. He told me that there were no Asian parts - all German although not all MB. He told me that MB pistons had had a problem with correct sizing briefly and told me that the rebuilt engines either got sleeves or not depending on the spec's and what was possible. He sounded reasonable and reasonably intelligent. I'm guardedly hopeful. We'll see. It's supposed to be delivered to my indy in Santa Fe the week of the 19th of this month. Photos when she's up and running again and I'll post monthly reports on any issues. God it'd be wonderful if it's a good rebuild and I can start obsessing about a really nice paint job, interior stuff, and non-essential bits and parts.
