captspillane seems to be the only one that is knowledgeable on this and he has not been on the site for several months.  Try to PM or email him directly for best results.  Good luck!

I am interested in this project and i think it is a cool idea.  However, the SD-4 crank and the mercruiser crank are not the same.  The mercruiser crank is made from ductile iron and the SD-4 is forged steel.

I misspoke, the marine cranks were made of nodular iron.
