mopar crank?

[dunni6]

I have what I think is a 440 crank but I am not sure. Need some help with the numbers. First # I seen are 2206 and then the # 17 stamped sideways next to the 2206 . Also this # 2206180, it's a little rubbed off but I think thats the #'s. I would appreciate any help. Thanks, Don

I have a 440 forged crank sitting in my garage. I think on one of the counter weights it says 440..I know it says somewhere..
