Blocks are cheap, unless you want # specific, and that might raise the
price to $200...still cheaper than line boring. Yes, when you order a
Schneider or any other performance guys, you can have the blank custom
turned to your journal.

Question: has anyone done, or have done, this (line-bore) operation on a Corvair block???

>> Mike- I have heard of it being done, but more often, I have heard of people getting either custom cams with journals being ground oversize to compensate for a worn out block journal, or, have the cam journal spray welded and reground to build it up, like this:
