At first I thought is was going to be a DIY thing. Was I wrong.
Thanks for posting

Anybody know what they use as the mold material?
I remember using simple sand in the eighth grade in industrial arts. Just found this, FWIW. Green sand (an aggregate of sand, pulverized coal, bentonite clay, and water) has traditionally been used in sand casting, however modern chemically bonded molding systems are becoming more popular. The most widely used casting sand is silica (SiO2).

Great video. It's good to see not everything is made in China or Taiwan.

It is just amazing the things “we” have been able to design and build- the milling machines used to finish the casting are simply incredible, especially when you realize the tolerances that must be held over such a distance.

Yeah, that milling machine is as big as a house. Pretty amazing stuff for sure.

Very cool video. Getting those things right is a huge deal--they are hard to R&R if somebody sticks the wrong bearings in the mains.

Copied one of the YouTube comments below the video.........
This is nowhere near to being a Mega Ship Engine. The Wartsila Sulzer literally makes this look tiny...this entire engine is 350l. Just one cylinder of a W- S is is 1800 litres... I remember as a kid working for GM's Terex Division as a machinist in Hudson Ohio. They had a separate building where they were putting together their prototype missile carrier for the MX Missile Project (which was never approved). Anyhoo, this vehicle was so big you could walk under the engine and look up at it. It was a massive Cat diesel. Never saw an engine that big in my life but it was Tinker Toy size compared to the subject engine.

Too big to fail

The 2nd video which goes over the complete assembly and overhaul is even better

In another 100 years, they will look back at this 1920's technology.
