    Interesting metallurgy patent info.
    https://www.govinfo.gov/content/pkg/...1a37c149b8.pdf

    General Motors has more Patents then I care to read lol!

    A reputable company that deals with US patents I will call and ask some GM questions.

    Recycled steel and various other metals can be used to make a myriad of products.

    Cast iron is a more generic term

    There are many types of cast-iron alloys, but the four primary categories include white cast-iron, gray cast-iron, ductile cast iron, and malleable cast-iron.

    In order to get a consistent "Batch" at the foundry the materials have to be a well managed blend of several given substances.....

    Bumpers off a few Toyota pickup's, a handful of rail road track and sundry cast brackets from ancient tractors is not gonna cut it...

    Repeatable mixtures of the required elements in huge quantity are required.

    I do believe most recycled materials are used for more mundane items.....A batch of fenders made from scrap car bodies.....VERY POSSIBLE

    We have an outfit locally that takes in huge quantities of scrap steel....They turn out rebar and steel T posts (The green/white fence posts)
    They ship out huge rolls of rebar every day...

    Steel sheets and such can be made from a lot of recycled materials.....

    Engine blocks have to be a bit tighter on the mix...Steel fenders can't be made into cast iron....

    The owner of Twisted Steel Performance most graciously donated a lot of P400 block material for my metallurgy experiment lab testing. Definitely more then 5 grams! Thank you soooo much man!

    Here’s the block identification.







    The drill sample location:



    The material in the test tube:




    I only have 2 more blocks I need to get material for before I send the samples to the lab for testing. Soooo exciting!

    When my blazer is out of the shop, I’ll get a sample from its Optimizer and a sample from customers 85 6.2 block after I pull it. Just progress is slow because parts are on back order.

    Pull it apart soon to see what is savable.
    It was sitting out in the weather for quite a while,water was leaking out when i winched it up my rollback.
    I hope i can salvage more than the injection system.
    Hopefully the block and crank are salvageable.A bore job will probably be called for.
