Driving down the road Friday and saw this, but it was too late to take a picture. Saturday I was that way again and had the opportunity to take a picture. I'm guessing it's out of a locomotive or ship engine. I paced it off at roughly 18 to 20 ft.

Big damn Buick or Packard maybe. 
Straight eight glory.
That's not a straight 8,
that's a STRAIGHT 8!!!!
They really need to store that on end so it doesn't take a set. Anyone got a moment to help me lift it up?
The extra long bit in the middle suggests that it's an I8 made by hacking two I4s together, possibly even with completely separate blocks.
That's AWESOME! And HUGE!
Interesting that there are no counter weights on that crank. I suppose at the 600 rpm that thing likely spun at, maybe they aren't necessary?
'Bout the same size as the ones I inspect every day at work, except they go in gas compressors.
The really big ones only do about 100 RPM.
In reply to TheRyGuy :
I'd think 600rpm would be very high for this sort of engine... don't these large industrial/ship engines run in the 80-100rpm range?
Then again I am also thinking of engines with strokes measured in meters, so maybe this little thing does rev high like that.
They really vibrate a lot when you shift the cam and run them backwards. You know, to back up and E36 M3.
You know that guy that recreated that Ferrari engine in miniature?
I'd like some billionaire to recreate it to the scale of that crank.
I used to use a machine shop that had a relatively large piston and connecting rod sitting out front.
The rod was about head height. I would marvel at that whenever I was in there.
That is bigger than the locomotive cranks I worked with. And those engines were 188Liters - 15.7L per cylinder. At full tilt it turned about 1100rpm. Idled at 300.
Apparently chrome plated journals are a thing on those engines.

Not just "those".... I remember seeing ads in the 80s for companies that would chrome-plate crankshafts for performance V8s, and probably anything else you wanted. Not sure if they are still around.
When I was having my Ford T5 input shaft cut down to Chevy pilot size, the machinist cut it slightly under because that was coincidentally how deep the hardening was. Da Boss's dad said if I was worried, I should send it to Chrome-A-Shaft in Memphis. I am not particularly worried... if I was that worried, I'd source a GM gearset.

Explains why the journals are not rusted, I was wondering

Check this out:
Oh man, you know when you're out west and you pass large ranches with massive gates. I want two of those cranks buried vertically in the ground with a half dozen regular small block cranks to form an arch over the top.

Those engines generally have a 1.5m stroke. This one looks quite a bit smaller- maybe only 2ft.
I'd bet it's out of a locomotive. Tug boats tend to have V engines in them.
That's the crankshaft out of a GE FDL-16 engine used in a locomotive or tugboat.
It's for a V16 four-stroke. An EMD 2-stroke will have more car-like counterweighting.
This engine:
Makes 4.5khp and 4.4kft-lbs. Weighs 45klbs.
Edit: Is it really this engine? The cylinder spacing is uniform...
Dude has a big crank.
In reply to GameboyRMH :
Looks like a pretty common turbodiesel. We used ones that looked just like it as generator motors on the ships I sailed on. There would generally be two of them plus an emergency one somewhere.
In reply to 1988RedT2 :
I was about to say that there must be some law about having your crank exposed in public like that....
