    none of them are forged. they're nodular. better than plain cast, not as good as forged.

    if ya got a forged crank from factory you won the lottery.

    LS7's/9's are forged.

    LS1's are cracked powder like the rods IIRC. Better than nodular.

    Some people have pushed them succesfully to 700+ (flywheel). They are a stout piece no doubt.

    you can get them treated by machine shops to make them even stouter. it is definately a formidable piece.
