Mopar M1 identification help

[scdetector]

Hi,I need some help to see what this intake fits.It has set in my dads garage for 10 years and never used. It has Mopar M1 and P4532757 stamped on it.I cannot find any info on that part number. We are thinking 383-440 but unsure.Any ideas??

Definetly a BB Mopar race intake, but the numbers don't jive with my current catalog. I'm sure somebody here will dig up the info for you.

Yeah, I concur on a RB intake, looks a little wide for a B 383. Might be a rough cast that is not in a catalog or was superseded by another number. sometimes the casting number is not the part number, but weiand made an intake that has the bathtub integrated like this one, although this one looks alot better.

the number on the intakse manifols is casting number, not part number, therefore you don't find any information with that number. Should get a pisture form the port side of the manifold, but I believe your intake is a 440 for Stage VI raised port heads. It's wider than any other 440 intake, and hte same one used in 575hp 505 cu in MP crate engines.

So, it seems itäs for Stage VI max wedge heads on a RB block. It doesn't fit any other heads because of the width and height, except for regular stage VI's opened to max wedge port size.
