Chrysler LA / NASCAR 355 cu. in. crank shaft

OK, I got coffee and checked.
Book said 1053.
I was told this is not as strong as other cranks. I don’t remember off the top of my head the pecking order of the number designation. It doesn’t matter much to me now since I have no idea how I’ll use the crank.


Yeah, I think 1053 is the material used on the OE cranks and the 1018 was what the “Kellogg” 8 bolts were made of. What book did you find that in?
