Jay, I am on the fence about these heads…
I would like to have a set just cause tunnel ports a cool 
But I don’t have anything to put them on at the moment.
I’m glad you are casting them though.

I just finished watching the interview, it was pretty cool.

I need to go search the forum for the intake manifold testing that I missed.

Glad to hear things are starting to finally get moving a little bit at the foundry, maybe 2023 will be the year I get to put a new engine in the old truck!

The most tragically stupid one I’ve ever heard of, and I’ve heard of quite a few, was a crew of oil field workers, dealing with a bunch of water in a pipe that had frozen.

What I find so tragic is how there were many full grown adults who were present when it happened, and how no one called out for the stupidity to stop just baffles me.

So here’s what happened…..
A crew of guys, probably 12-20 guys, we’re trying to pump water under high pressure into a well, the process is called fracturing, or Frac-ing, you may have heard of it. The pumps are massive, usually a v12 or v16 diesel mounted on a semi trailer. Water comes into the pump through a 4 inch low pressure hose, and leaves the pump through thick “iron” pipes, these have a bore of about 3.5 inches and the steel is about an inch and an inch and a half thick. These are designed to withstand 10,000 to 15,000 psi generally.
Frac-ing in winter time always is a challenge.
Well, these guys were not having a good day, and they froze up a length of iron solid with ice. The iron is usually in 4 foot to 8 foot long sections.
So they pulled the iced up length of iron from the rest of the stuff, set it up where they could work on it better, and proceeded to heat it with a propane weed burner to melt the ice. By now you can probably guess where this is going. The guy who was standing in front of the open end of the pipe died instantly when a 4 inch round chunk of ice blew a hole clean threw his chest.
How no one involved saw the danger there, still just boggles my mind.

I bought an ender 3 V2, Not as fancy as the pro. By the time I was finished buying all the extras to go with it to print the carbon fiber nylon, Hardened nozzles, filament dryer and a roll of the Filament, I had spent about $500  . Pretty impressed with it so far, I haven't really even tuned it yet and it just works. There is room for improvement, but for now, just prototyping and getting used to it.

I keep going back and forth on the aftermarket block issue. I don’t know what the actual weight penalty is on the block, I’ve heard about 60 pounds ? Has anyone actually weighed the two? I have a stock block I could weigh.

...Introduction tutorial on Dual fuel Diesel engines ", since, at the time we were cutting our teeth on Diesel engines that would run Natural gas in tandem.

Most of them fell for it hook line and sinker. Good times.

You ought to look into multi-fuel engines.  Basically just a diesel engine capable of running on gasoline, jet fuel, diesel, kerosene, white gas, or anything combustible that could be injected into the cylinder.  Continental was a big manufacturer of these engines for military use.

Not sure those would do us much good, we usually have anywhere from 14-20 2200-2500 HP engines running at a time, almost continuously. Each one will burn about 70-90 gallons an hour, it adds up quick. Natural gas is readily available, so if we feed that into the pumps it can cut our fuel consumption roughly in half. Being able to run some other form of fuel doesn’t really help.

Very cool heads indeed! I wonder how that engine would fit in a shock tower car w/o cutting up the inner fender wells.

ive wondered the same thing. those heads would be a tad on the overkill side on an 8.2 inch block, but I sure want to see one
