Help with aluminum Intake ID P4532063

That’s what I thought but when I googled it my search never would confirm the part number.

I wonder how it would perform on a low compression motor with a set of the 440 source or edelbrock rpm’s?
73 Challenger, auto, 2000 stall 3:23 and a comp cam extreme energy .477 / . 480

When I searched it I came up with another number even though I specifically searched the number on your intake.
What I saw was that the same intake could have either number.

Being an M1 and a dual plane tells me it would do just fine on a street car, but then I don't have a lot of experience with big block intakes.
I probably would cut the center divider though for better carb signal, or maybe use an open spacer.
