I think it's a Moroso pump, Brian we will have to have Ed Cook give us the information on the pump. Ed Cook asked the same question a couple of years ago when he was having all sorts of issues blowing oil all over his engine bay.

I went through all the part numbers and gave Ed the information to research the pump. I am sure Ed Cook will post the info we are looking for when he reads this. Ed found the pump and is using the same exact pump in his SuperCar Road Runner and I am sure it will be in the '63 Super Max Wedge.
In the HP2 I installed the pump on a toggle switch inline with a relay. I am now able to power the pump on and off when I want. I personaly like it on all the time on the HP2. It goes with the old Cop/FBI car image

, sounds like a siren. I like it

.
On a 1971/1972 small block Chrysler I would not go to the PCV. I would run the pump to the breather. If you're not liking the siren sound it makes install the pump in the heater box like I told Ed to do.
