Just a fyi I ordered one last July and still haven't got mine yet. I've been getting the run around for the last couple months. In my pursuit to get my block I've spoken with some guys on FB that have had similar issues. One guy had to spend a lot of money on extra machine work to get his right I think he just got the motor together but hasn't run it. Another guys block is it best machine being checked for issues now.
I heard they were having casting issues but the info I've been getting is they've fixed those issues. If and when I get my block it's supposed to be this weekend Its going right to the machine shop for a once over.
