Mopar Forums - Mopar Experts Please Help Identify this camshaft

I bought online, what I was told was a correct NOS camshaft for a 1956 Dodge Coronet, with the 270 Poly V8. I had been searching for the cam, as I was having the motor rebuilt. When the cam arrived, it was clear it was not the right cam for my motor. I was hoping someone here, with a lot of old Mopar knowledge, could identify what motor it is for. I'd like to sell it, or even give it away, as opposed to throwing it away.
