Help with aluminum Intake ID P4532063

i am working on an old project i started about 17 years ago. So a lot of my parts are from that time frame so there have been updates and new items.
I had purchased this dual plane and I think it is a copy of the factory HP intake maybe even an M1. But I am not exactly sure so I could use some help with what it is..
Thanks!

I find it as a Mopar Performance big block M1 dual plane.
