Re: [Chrysler300] 1962 383 Water Pump Housing Question

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

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 .

Does anyone know the differences between a 1962 Water Pump Housing & other years?
I have one that is (I think) from 1965; for my 1962 383 build..

The 1962 temperature sending unit is a small diameter thing.

This Pump Housing I have has a much larger diameter sending unit hole.

I have a new water pump, listed for the 1962.

This Pump Housing I have won't allow the water pump to seat inside it all the way; with out scraping the internal casting.

I assume I need a correct Pump Housing and this one won't work for my build...?

Anyone know what other years might be A-OK for a 1962 383?

Thanks!
