Simply put, the base material (grey iron) is not that which can be surface hardened like a steel crank. Of course there are many types of cast iron, some used for lifters are surface hardening type (white iron).
I have been looking thru notes I have and cannot find the exact material ordered, I still have a ways to go. I know that it is not a very hard material as I had to machine some parts of it on the lathe (fitting into "A" block), Dan then told me the material.
Some people have had really good luck with them, it all depends on the actual usage of the car/motor and the proper oiling system. I do not recall anything outstanding over a Ford "C" crank, other than the oil seal area is ready for the 2pc chevy seal and the flange should be stronger than a stk "C" crank.
If you do a search for Meehanite iron, you can probably find the alloy/engineering documents.
