Is a Nodular Iron Crank unusual in a '72 455?
I pulled the oil pan on my '72 455, and was suprised to find a Nodular Crank. I though those were used on the '68 to '70 engines? Was it fairly common on a '72 as well? Came out of a Vista Cruiser.... Thanks. Tom.

It says in the Olds FAQ crankshaft I.D. Wiki that the 455 crank could be nodular iron or plain iron and that the N means nodular? Is it also in need of correction?
