I’m sure the shop did sonic the 400, but I’ll need to look for the paperwork. Would be interesting, I’ve seen people say on here that 67 400 blocks have the thickest walls and webbing.

A friend of mine got a aftermarket block sonic checked and had some .170 - .180 numbers . I was surprised . So to me if you can beef up a stock block it might not be so bad . Seems like you never know what you're going to get even if it is a aftermarket block as well..
If you get any numbers on this 400 please share them .. That's why i started this thread , so i could compare my numbers to other blocks but it seems like theirs not to many people besides you and bluleghost...
