OK.  I dropped the pan this morning.
It's trash.
The #2 rod let go and curled up like a pretzel.  The piston is shattered and there's a few chunks taken out of the counterweights of the crank.
 
I'm selling the car.  I don't have the money to fix it.

Sorry to see it got toasted Stan... is it me or does it seem the big
blocks have more than their share of bottom end problems...I had a spun
bearing on 2 of them and only ever owned 3.

I'm starting to think along the same lines.  This is also #3 for me.

Ya, I'm hoping the BB in my '58 is durable - I've heard the 350 and the
361s are darn near bulletproof- lots of meat in the bottom end and
block for relatively small displacement.  I'm thinking they were
at their outer limits when pumped all the way up to 440 cu in.

The 361-383 are very stout and have a good rod/stroke ratio (1.88 to 1) so there is not a lot of side loading--good for bore wear and stress on the rods.  The big 440 still has a very good rod/stroke ratio (1.8 to 1) but it is just low enough that it can put too much load on those little 3/8" rod bolts at high rpm.

Basically, if you want to spin your 440 fast (above 5,000 for any length of time) it needs aftermarket rods with BIG bolts and maybe a main cap girdle too. The huge mains (2.75")have a too high a bearing speed above 5,000rpm, so if you've got any cap walk at all you'll spin a bearing and risk detonating the engine. If I'm doing a complete rebuild on an RB it gets new rods with ARP bolts. 383's will do with just the new bolts.

From the photos it looks like the WOB broke a rod bolt.

Well, I'm probably the only person in the south stupid enough to pull an engine in the dog days  of summer.  But my my pal Lance The Destroyer embarrassed me into it.
Here we go again.............
 
 

 
 
I think my cheapest option right now is a reman shortblock.  I'm gonna start checking prices.

Don't bump into that thing!!!
 


I'm not a big safety nut, but that looks scary to me Stan.  Isn't there a better way to stand it?

How do you see the chain of events happening? The rod could have let go and the piston jammed in the top of the cylinder and a valve slammed into it and snapped the camshaft which destroyed the lifters and valley. I suppose it could have started on the top end too if a lifter imploded and jammed the cam and forced a valve into the piston which bent the rod. Have you pulled the head to see what the top of the piston and the valves look like?

The tops of the pistons and the valves/heads look fine.
 
I can't figure out what happened.  All I know is the end result which is total mass destruction at the front of the block from the #2 cylinder.  If I HAD to make a guess....

Shock
 
The rod let go and there was so much inertia in the cam it let go from the shock.  Scene it before.
 
If the block is good, you can get a cam, crank and rod and save it.
