I'm wondering if the early 8-bolt 318 cranks are steel or cast. I'm wanting to build a "stroker" (: 301 by changing the crank & pistons but my machinist said the reground 318 cranks he has access to are cast whereas the 277/301 cranks I currently have are steel. Did they make them both ways or is his supplier mistaken? It's not like it's going to be a high rpm engine but still, steel is obviously preferable. Thanks, Loren
