Please help me identify this PS pump. I believe it is a later Saganaw pump with cooler, off a 440 Police car (75-78). I don't think it is off a small block. Its definately off a Mopar. Can any one varify this??? Would it fit any 383-400-440 motor??? Thanks for any information.

Saginaw for sure big block
bracket may be for ac car

What are the differeces in the pumps between air and non air cars. Maybe size of pulley? Offset of pulley? Different high pressure hose?

I just pulled one off of a 75 440 air car that has the cooler...The pump and bracket looked different as the pulley was farther away from the pump... (1st pic)
I'm not sure why but the brackets on the pump you have sure look like 70 up small block...The slot would rotate from the drivers side bottom bolt on the water pump.
The bottom pic is the pump on my 383 with no AC...
Definitely different than the one you have...

That is definitely a Saginaw and I believe those are small block brackets. They look exactly the same as what I have.

This is a later Saginaw with a cooler, OK. Now, is it for a small or big block??? Thanks everybody.

Yup, small block. You can use that pump though with the proper brackets. Mancini sells them.
