Ok, i have the engine out and at my home garage. I power washed it of 59 years of caked on grease. Ruined a set of shorts in that little operation as the stuff just will not come out even with my usual grease removing tricks. Also did the wash a little close to the closed garage door and had to wash the house down as well, so as not to be murdered by my wife...her patience is only so much :thumbsup:. Block was cast on 8/2/1965 by the night shift. The casting number is 2465330-3. The front driver's edge is stamped B273-11-6. The SO shows the car expected assembly on B10 (11/10/1965).

Removed the heads and all the lifters are mobile and looked good. Here is cyl #2 that was the only one that never leaked down from the MMO, ATF, PB Blaster, etc. over the month or so it soaked,

Aside from the carbon I can't see any good reason on the top end for it to be seized, other than frozen rings. Here is the whole passenger bank.

and the driver's bank

The cylinders are all looking pretty good, but there is a distinct 'top of travel' ridge on each one, but then at 235K miles that should be expected.

I did find a fair amount of a grey "crap" in the recesses of the galley, Is this casting sand? (pic of it on my finger)

Will turn it over and take a look at the bottom end next weekend. At this point its either frozen rings (in Cyl 2 at least, i suspect) or the crank is locked up. From what I can see looking from the top end, the crank does not look bad, but it has to be something, and my money is on frozen ring(s).
Will keep you posted.
