I know the M1's come both standard port and raised port configurations for RB engines. My 440 RB heads are standard port. Im looking for the part number for the M1 intake with 4500 flange and standard port size. Does anyone know the part number?

Bump

I do believe its P4529725, its the number I got from one of AndyF's articles here: http://www.moparmax.com/tech/2011/vi_8-flat-6.html Also the last time I tried to find one it was no longer being stocked.

That's the one.

Ask your local Dodge dealer to run an inventory search. There is probably some guy in the midwest who has one sitting on his shelf. If you buy it thru the dealer then freight is free.

Andy some parts guys suck though.Luckily I knew 2 that were great.When I got my M1 it was like a month wait for it.My buddy got it for me at like 150 at the time.Same with power pak for 66 Charger dash NOS for 60 bucks.Found me a fuel sender for my RamCharger also.Was suppoosedly the last one out there.He even found me some NOS upper 65 Bbody control arms.He knew lots of people in dealerships and could get stuff.Sure do miss the one guy.Rocky

Hi Rocky did that Parts guy retired or did you just move to a different location? If he still working for Dodge will there be a way for you to get a hold of him for me or for me to get ahold of him?
