Water Pump Housing

mopar performance ONLY! DO NOT GO WITH 440 SOURCE. buck up the extra coin and get the mopar unit. they are a better casting. the 440 source unit has restrictive casting.

Thanks, I bought the P4286900.


Better make sure what your doing. The cast iron pump is for up to 69. The lower hose is on the driver's side. Aluminum pump is passenger side. I think you need to change the timing cover and balancer to the later style. AFAIK, there are 2 different aluminum pumps. Standard, and police. Standard has holes around the WP shaft .They are known for breaking. The police style doesn't have that, and has a larger shaft to keep from breaking.

My engine is 67 HP 440 engine. The lower hose is on the drivers side.

Unless I'm looking at something wrong. The MPP waterpump is no different.

"These aluminum housings simply replace the stock cast iron housing. They include the appropriate accessory bosses for both early and late model engines."
