Johnny,
We cover so many topics on the phone...and even across hours, I feel like we are only scratching the surface.
I've been on contact with Perfect Bore since last fall, they are fantastic to bounce ideas and questions off of. They are however, fairly expensive. (What do you expect from a firm that supplies F1 teams. LOL) I'll email you my contact's email addy shortly.
You are correct about the history, although I think it was around 2008 that Capricorn took over Perfect Bore. (Perfect Bore used Poeton for years, then eventually bought them) I have a number of very technical articles about Perfect Bore/Capricorn that I should be able to share with you privately. (From a high end racing technical journal)
From what I understand of their processes, they are able to re-finish blocks without acid dipping as we discussed previously. You'll be able to get more specific answers via email.
Regards,
Adam
