Re: [AMC-list] 401 water pump pulley

["Armand Eshleman" <aje1@xxxxxxxxxxxxxxx>]

I think he's looking for this information.

390 and 71 401 water pumps have a dfferent distance from the gasket surface 
to the face of the pully flange than 72 and newer V8s including 401 pumps.

I believe the dimensions are 3.5 inches 390, and 71 401

and 72 and newer V8 the distance is 3.75 inches
