LA - Cast cranks ( Dont throw away )

Krooser said

I believe all the cast Mopar cranks are cast steel not cast iron. True Ford did use nodular iron cranks but those NASCAR cranks were from outfits like Moldex and Hank the Crank... billet steel. I ran Cleveland's in my dirt cars for several years... always used stock stuff because i was poor (and still am).

Nope. They were nodular iron. Either that or Forged steel. Mopar never offered the cast steel shafts from the factory. Mopar Performance did as an aftermarket piece. I think they were made by Eagle. The Cleveland cranks I am talking about were box stock. THey may have had some fancy machine work done like fillet radii and knife edging, but they were the stock pieces. You are correct that there were aftermarket pieces available, but I am not talking about those here.
