Did the 360 ever come with a forged crank?

I appreciate that this post is not really responsive to the original question ("did the 360 ever come with a forged crank?"), but for those who are curious, there were three billet steel cranks for the 360 (i.e., large main journals) available from the factory for those who wanted to go racing: the P4529819 with a 3.55" stroke; the P4452978 with a 3.58" stroke, and the P4452979 with a 3.79" stroke.
