April 17, 2007 - The engine is going to have to come apart again.
I'm still trying to sort out why, but the pistons are standing proud of the block. Not good. Usually I'd do a quick check of this after installing the first piston, but this was the third engine built with pistons from this batch so I was pretty confident everything was good.
Well, it was supposed to have been built with known pistons. A check of the paperwork indicates that an experimental set of pistons intended for use with a stock crank may have ended up in the motor. I need to do some more checking on this.
Whatever the reason, it appears I'll be tearing it all apart again. At least I know the clearances are good now. Sigh.
