Yes....good point.Well, neither of us died until after leaving it. So it's a slow-acting curse.
Haunted hill.....sounds fun..
Man that really sucks to hear! It was a cool project.
Maybe it's a sign, you can focus all efforts into one rig instead of spreading it over multiple.

Still is a cool project. It just slid back into project status instead of DD status.
Ok, I found a 6.2 long block and decided that was the best path forward. My brother came up for the UPO wheeling trip this weekend and stayed an extra day to help me with the engine swap. We worked steadily from noon on Monday until Noon today, with no time for pictures. I borrowed my buddy's bucket tractor for moving the engines as needed. Old engine is out, new engine is resealed and seated in the motor mounts. We tried to get the tranny wrangled into place but simply ran out of time (he needed to leave).
List of stuff done to the donor engine:
Rear main seal
Oil pan (robbed from the old engine)
Timing set
Harmonic Balancer (Duh.
)
Motor mount brackets (several layers of havoc here
)
Water pump
Fuel pump blockoff plate
Vacuum pump (robbed from the old engine)
Injection pump (robbed from the old engine)
The new engine came with most of the needed parts, minus the IP itself. But the pieces were loose, so we kept the best pieces and tossed the rest into the scrap heap. On the bright side, the new block didn't show visible cracking in the webs. Dat's good.

At this point I need to install new injectors & plugs, reinstall accessories & intake, and connect wires & tubes. Button up the tranny mounting and it'll be back on the road. It's amazing how much easier this is the second or third time through. I have my wires & bolts memorized since it's almost identical to the suburban engine. And, yes, I do have 13 or 14 hours invested into this by now, but that's a lot less than it took on the burb.
Oh, and the hood is off. We're expecting a lot of rain this week, so that's mandatory.
I'll grab some pictures now that we're not thrashing on it.

Wowzers. The list goes on and on, it seems like a good setting for a horror story. I made it to the flat section, but I don't think that was quite the top. No view at that level.
We'll hafta go back sometime and locate that adit.
A sucky win, eh? The burb wound up doing a much better job than this truck would have. More capable and much more roomy. With 5 people (my brother tagged along) the full-width rear seat and extra doors were quite handy. And while I did change out a caliper on the trip, I wasn't constantly fighting with the brakes, like I would have been on this rig.
I'm trying to see the happy side here.
Here's a mini trip report from the scouting weekend. We were just getting started when it broke, so I hadn't bothered to photograph much. It started out as a rainy weekend:
I hit 7 construction zones in the 2 hour trip up to Marquette. But otherwise traffic was light.
Met up with Luke, talked about his newly-finished tailgate conversion, and hit the road out to the boonies.
Here is our first obstacle. I think I stopped because I was slipping and not on the correct line. I do remember getting further than I had when @Monty5150 and I tried the same climb.
We walked up the rest of the climb to see what the mud hole at the top looked like. The climb was fine, but the mud holes did not have reachable bottoms, so we opted to turn around and run other trails. Luke's kid started sinking into the hole, so we had the fun of digging him & his shoes out with a stick.
I backed down the hill and waited for Luke (who ran to the top and then turned around). Thimbleberries were in peak season. Yum!
Walked down another trail before deciding to head back to the highway and take a whole different trail through the woods. And that's when the truck broke. I rode back into Marquette like this:
Coming into town I missed the fact that Luke was turning and wound up running over the strap. We gingerly decided to try crossing town anyways and headed into the city. The weakened strap snapped at the very first intersection we came to. Of course there was traffic, and of course it was a roundabout (new enough to not be listed on the maps yet). So as I'm coasting to a stop in the middle of the circle I crank up the engine and it roars to life. I throw it in third and run it WOT for about 4 seconds. It drives normally aside from the hideous clatter. Once the intersection is behind me I shut it off and coast into a nearby parking lot.
I decide to call AAA from here rather than trying to tow through the rest of town. Marquette doesn't have any good towstrap routes from North to South, so I decided I would deal with towing the last few miles instead of the first few miles.
Up she goes.
It was 126 miles to home, and AAA would carry me 100 miles. I picked a drop-off spot on a longer but quieter highway that let me bypass the town I live near. No use towing through town if I can go around it. I had wifey meet me and was towed 40 miles like this:
Yes, the strap was too short, but it's what I had available after the good one snapped. I immediately bought another big strap so I wouldn't repeat this during the UPO trip.
And here was the final resting spot. Rest in pieces, my undeserving friend.

Thanks for the link, that was a cool story. I seen the YouTube video of the book that was written on the lost silver mine.
Very cool
Pictures as she sits today. Freshly resealed long block just needs everything that makes it an engine. 
Time to start cleaning up, parts were strewn about as we raced the clock. Friday starts a week of rain storms, so all this will be buttoned up tomorrow.
The trailer makes a pretty good work platform. Until it gets cluttered, of course.
Plenty of extra parts came with the long block. I think it's all going to scrap once I have assembled a working engine.
Tranny is close but the rear of the engine needs to drop more before they will line up. I may wind up tearing out the new flooring so I can remove the transmission tunnel and raise the tranny up to the engine level. I lifted the front of the engine but only succeeded in raising the truck, the angle was still wrong. The shift tower is already shoved into the floor pan, so something needs to change. I suppose I could pull it back off the motor mounts.

Today I tore down the old green block just for fun. The crank broke on one of the offsets, so the two halves are loosely locked together. There's about 15 degrees of slop between the sections.
I'm keeping these pieces as souvenirs. Tech note, there is only one piston on a 6.2 that can be removed from the bottom. The rest must go out the top. Also, every part of this engine is ridiculously overweight. This thing is obese, even if it's not heavy duty.
A majority of the rod bearings were trashed. The babbitt was worn away and revealed a copper layer underneath. I'm pretty sure this stems from the time the engine ran for ~10 minutes with no oil pump. But oddly enough I never had any rod knocking. I kept a few of them as a reminder to check more and assume less.
@AgDieseler, this looks like a textbook case of brittle fatigue failure. Old beachmarks through most of the surface and then a brittle fracture at the edge. This thing has been failing for a while.
Who would have thought those engineering classes would actually come in handy some day?

Suspicion confirmed, it was toward the rear end. Oddly enough the block didn't look damaged during this flopping around.
I did have a gut wrenching moment when I found a 1/2" piece of cast iron in the baffle of the oil pan I took off the donor engine. But after a bit of searching I found that it came off one of the rear pistons. Phew. For a moment there I thought I built a known bad engine.
However, if the con-rod pin broke through it does mean I came pretty close to knocking a hole in the side of the block.
All those extra parts you have you can sell, make a couple bucks back.
Hmm, where the crank broke has me curious as most break close to the front of the block. Mine broke just after the number 2 main. I wonder if your flywheel is slightly out of balance. Or like you said, just a poor casting that finally gave up.
Their surprisingly stout little engines, once you take care of a couple little things as your finding out.
Try titling your engine with the vacuum pump out, it might be hitting the firewall.

Speaking of extra parts, I'm looking for a dual throttle cable bracket to hook up cruise control.
