Well, I've got some good news and some bad news:

The good news is that today Larry Weidner and I carried my Cad 500 to the
machine shop to get it checked out and prepped for installation in the
X-Birchaven. :-)

The bad news is that it's not really voluntary. :-(

For the past couple of weeks I've been seriously trying to get the kinks out
of my EFI, including adding the EBL flash upgrade to the ECM. Over the past
week or so at a fast idle of around 1800 rpm, I've noticed a rat-a-tat-tat
that I really couldn't hear well enough to identify. When Larry & Lucy
arrived, of course Larry and I had to get greasy. With his functioning
hearing, he was able to make an ominous diagnosis. By pulling plug wires we
confirmed that #7 rod's knocking. :-((

No explanation unless my NASCAR engine builder friend's first hypothesis is
correct: Predetonation. I've heard no pinging EVER from this engine. Then
again, my straight through steel pack mufflers are REAL quiet. And the
engine has not been under significant load since we went to Santa Rosa last
March. But I have been installing and tuning a Computer Controlled
Distributor and running some pretty large spark advances, though only under
no-load conditions.

Oh well, with only lemons, one must make lemon pie or lemonade.

Dependent on the engine builder's progress, I'll soon remove the engine and
open the bottom end to see exactly what's happened. I do have another
perfect, already polished crank in the shop, so I'll probably stick it in
there after cleaning up any debris.

Rick, I'm sorry I somehow damaged "your" engine. :-( Since this is the
second essentially unexplained #7 rod bearing failure in this engine, I
don't think you should install it.
