340 crankshaft value


Chrysler didn't just use "cast iron". They used nodular cast iron which is stronger. Much the same as a lot of the cranks Ford used. 351C, most all of the FE engines, the 351M and 400. They are pretty stout. Even the slant six cast cranks are nodular.

Here is a really nice article about the difference in regular "grey iron" and "nodular iron".
