Was out of town for business, so not much got done...
The starter fits now - my apprentice-level mill operation didn't come out too bad...
I threw the crank in it and a slug in one hole. Nothing hits, but the rod to block clearance isn't enough, so I need to do some grinding in there.
While I had this much assembled, I figured I might as well throw a head on it and check piston to head clearance. I've got .050 more than I had before! That means that the old blocks after years of align boring and decking had .050 less deck height than they were supposed to!
Clearance is good, but I started worrying about compression ratio, or lack thereof. I got out the CC equipment and CC'ed the slug in the new block. (I had my numbers from before, but I wanted to get the real deal rather than trusting a recalculation) The compression ratio came out to 10.0. A bit lower than I'd like if I were building this from scratch, but not low enough to cause major concern.
So far so good...
