Reading this reminded me of another bit of info I saved. Go about halfway down the page (pg8) and onto the next
page for some flow test on various pumps. Good info on the subject and does show different pump configurations Overheating
issue resolved....interesting read !

This is a really important subject ; Napa today gives you a 440 pump that “fits”413 but is often wrong . Some early pump block housings had steel plates inside to control flows
or take up space behind impeller ? Minor things like temp sensors or bolt tappings , one can deal with but I believe there are at least two pumps and two housings if not 4 in the early B blocks and they have differing pump impeller depth spec . The plate or
not is a variant too . Or maybe that fixes a too deep housing used elsewhere. Several wrong combinations fit ok but car will overheat .
I have never been a guy with all the part numbers in a book , — but if anyone really knows what
the main variations of housing and pump are physically we can at least match correctly . On the other hand getting some of the early pumps can be frustrating — you get 440 pumps . . So if the original 413 pump fails get it rebuilt or get a kit , lacking
solid info on crossing over — not hearsay. I think the AC / HD pumps had differing vanes too, from memory , —and while this may be wrong ,
I think oddly the ac or HD pump has fewer vanes which really confused me — seems backwards . Add that variation to set in depth and the plate or not , a lot of ways to go wrong . Today I would tend to purchase an aftermarket or Mopar performance pump and housing in aluminum
that go together , unless your old one is obviously correct / original and can be fixed . Also takes 25 lbs off the nose and will work right . I learned similar things from Don Verity on transmission parts , a big pile of seemingly the same
pieces ( as I had stashed up ) do not swap , keep all parts from any one trans together or else a fiasco . That said if anyone knows about this , or maybe Mr Merritt already has it up somewhere , an explanation
of the why —and physical differences —-would be really helpful . More so than numbers actually , although that helps . Posted as one 300 guy bitten by this .. Sent from my iPhone not by choice
