This is for 340 builders

Blown fish you seem pretty knowledgeable about this stuff so i myself have a question on this same subject. i have heard that old 318 y blocks all had steel cranks in them and are the same as a 340 crank. do you know if this is true?? if so i need a good kick in the *** for the ones that i have sent to the scrap over the years!
Bend over and brace yourself. I use them in my LA engines.
