Still need to add some of the newer heads
I know this is an old thread but I have been trying to find info on the heads installed on my 440.
P4532785. Can't seem to find any info on them.
Anyone have any info it would be appreciated.
That's a high number so I'm guessing a later mid 70's head?
Cool that's a start.
I searched the web and found nothing. Trying to get some specs.
Hopefully someone might come up with something
Thanks Cody!
P # are MP heads so it could be a Stage 4 or 5 heads
It has Mopar cast in the heads with that number. I'll keep searching
Thanks!
