I have been trying to find info on an engine I bought from a guy that was using it as a coffee table! And seeing this post shed more light on it! It is aluminum or mag not sure but the casting is 3-4-59 and 0-172978 with twin air research turbos.
Don't know about SB V8's, but know magnesium engines have been tried. Was at a magnesium showcase a few years ago, and had a manesium V6 block on diplay, I could pick up with one hand. Had no cylinder liners, and vender said didn't need any, except for current anti-freeze corrosion problems. Not sure of this, as magnesiun is known to light off at certain temperatures. Thing sure was light though.
Ya! Magnesium. A little startup company known as Porsche tried them for a few years!

The "potential" fire danger associated with magnesium is relevant to the dust particles, as in "grinding or sanding".
About 80 million VW Bugs had magnesium crankcase halves; lots of basic research on machining coolant fluids for light alloys was done in Wolfsburg, as they made about 6,000 of them every day.
Hi I have a block just like yours. It is a Magnesium block produced by GM there was 31 of them cast by GM. the one I have was used by Mickey Thompson in his 1963 Indy 500 cars and he used it again in 1977 for his Baja single seat race car. As far as fire is goes this one was in a fire. the fire was so hot the card was a lump of aluminum in the intake. and the plug wires were just the core. One of the fuel tanks which is only inches from the side of the block was gone except for the mounting straps.

Thanks everyone, especially Viking427 and Jim Lockwood, for the valuable information and photos. I had "heard rumors" of a magnesium block floating around and wanted to pursue it for my collection of "weird" stuff. If anyone knows the where abouts of one of the mag or aluminum blocks, please let me know and thanks in advance for your consideration.

I was looking through old ads, I have a rare 427 magnesium block. It was built into a 427 L88. Respond if you are interested - the motor is for sale. Larry 952-925-1162
Has anyone ever seen or heard of magnesium or aluminum small blocks (283 / 327) cast by GM and or Mickey Thompson? I know GM installed some aluminum 377's in the Grand Sports and Chaparrals ran some aluminum engines.
somewhere i have pics of a auction i was at.1800lastbid was the web site in ran on. the guys was a huge gm engineer, and if i remember right involved in hot rod magizine . he had warehouses full of GM PARTS. the auction was ran through a seller out of grandrapids mi. miedema auctions . about 3 yrs ago.. on a stand he had alum or mag sbc that was complete. it sold for aprox 10g if i remember right. it took several weeks to complete the sale of all the items. there where several crate GM blocks. it was a amazing sale to be at. im sure if you contact these people, they could tell you who bought that engine. troy
Hi,
Yes, I am attaching pictures of the block and the engine that was built.
Call me if you are interested. Larry 952-925-1162
I believe what you have is one of the magnesium blocks cast by P&S Engineering in Ohio back in the late 70s. These blocks were primarily for drag race applications.
I have some photos of literature on them but it is saved as a .BMP file and I can't convert it to a JPEG file. If someone can tell me how to convert from BMP to JPEG, I will post pics.

Do you recall what the weight of the bare block is?
