A relative told me about a 70's vega that had an all aluminum engine including the cylinders. Do you know anything about it? Has any other company done it(sucessfully)?

Chevrolet built a 4 cylinder aluminum block with a cast iron overhead cam cylinder head for the Vega... It did have a aluminum bore, the pistons had a tin coating which was suppose to keep them from scoring the cylinder... but many of them failed...some owners had the blocks bored and sleeves installed with new aluminum pistons installed.. vast improvement...
Several small engine manufactures use this same design...

The Vega engine cylinder walls were treated with some sort of a silicone, I believe, as were the piston skirts, but under extreme conditions, like severe overheating, or running low on oil, they failed.
