I wouldn’t trust magnesium for that application. It oxidizes far too easily, and from the pics it has no surface coating to protect it either.

I’ll rather have the Chevy “Hemi” engine sans the zillion dollar price tag…

Magnesium + high temps. Not a good combo.

I thought vw used either a magnesium head or block in some of the old beetles? I remember my high school chem teacher saying the local fire department rolled up on the scene of an accident and tried to douse it with water. Of course that only made it worse.

BUILDING BLOCKS.
One of the primary application areas for aluminum in vehicles is under the hood—as in blocks and heads. What about magnesium blocks? “There are magnesium blocks,” Showalter says. “On racing cars.” A problem with more conventional engine applications is that the coolant tends to react with the magnesium, causing corrosion. One of the all-time greatest uses of magnesium did occur under the hood—at least the hoods that were located where the trunk is ordinarily located. The VW Beetle and the VW Super Beetle both had magnesium engine blocks (AS21 and AS41, respectively). They were, it should be noted, air-cooled engines. (Audi, which is part of Volkswagen AG, continues to work with the light metal in powertrain-related applications. For example, the air intake module on its W12 engine is magnesium, as are various components, including the cylinder head covers, on its V8. The company’s multritronic CVT and five-speed manual transmission both have magnesium housings.)

Magnesium engine components on burning VW’s, not a good thing!!! That’s the same story I heard.

this Chevy Hemi ???

[SixSpeed454SS]

^^ That’s not a Hemi. Just an LT5.

The magnesium block would be better for a display in a museum, than for use in a car.

Buy that Magnesium block and throw it in a pool of Hydochloric Acid.

…And Run!

Buddy of mine had a bag full of magnesium shavings. We used to have bon fires and toss handfuls into the fire

That’s an Arias Hemi, not a Chevy hemi. It don’t look like a single Chevy part is on it.

ok, hot shot, show us a pic of a Chevy Hemi.

While he says it is a prototype, he does not say what the stated goal of the prototyping was. I would be interested in what GM was trying to learn by making these (assuming it is real). If it was a weight exercise, then I have to wonder why they just didn’t go with aluminum since it is more readily available and likely much less expensive. If the exercise were for something else, I’d like to not only know what they were trying to learn but also what they did learn.

…it would make one hell of a sleeper/cheater motor…

except for maybe the Chevy emblem. :ugh2:

I never said one even existed.

Nice.

I was talking “factory” Chevy Hemi.

Believe I found it.
