360 Came With A Forged Crank

Exactly. They were made out of the same material as the 351 Cleveland cranks. Nodular cast iron. Much stronger than plain old cast iron. The Clevelands routinely spun 9500 on the NASCAR tracks back in the day, so the stock 360 cranks are just fine.

And larger main journals than 318’s and 340’s.
