Early hemi water pump conversion questions

For SHAME those of you who would desecrate your early hemi with non chrysler parts....for shame.

On mine I made my own adapters also billet aluminum. Mine were 1-1/8" thick which puts the front of the water pump pulley at 7-1/8" forward of the block surface. And btw I bought an aluminum BBC pump brand new at teh swap meet for 40 bucks. Of course I stuffed this in my Rambler so clearly I am clueless. Shh don't tell anyone but I also stuck a FORD rear end in there too.

And btw I really do respect those who want to run a stock pump. I run one on my coupe - then again I've got no hood (or front sheet metal at all for that matter) so I prefer THAT one to look slightly more traditional. For those who run those pumps - I never did find out where to get rebuilding parts - so I would buy early mopar pumps (the wrong ones) because I lerned that they DID SHARE the same bearing and seal - some even used the same impeller. I've rebuilt several hemi water pumps. I always wanted to cast one out of aluminum - I even took a class in sand casting - I was kinda dissapointed when they wouldn't let me pour one. I digress......

 

So are you running the original ignition, 6 volt, tranny, canister oil filters, etc? Not being a smartass, just curious how deep your dedication is. I do have alot of respect for people that make every effort to be exact.

 

Opinions are ok but you finally have to decide. I decided to make my own adapters and use a SBC pump. The top bolt holes line up allowing me to use a stud all the way into the block. I had a number of guys say it wouldn't work. I get tired of hearing that.

Don't ever let somebody paint you into a box!!! If Desoto wants to run stock stuff, fine. Nobody is going to dictate to me what I have to run though!!!

Gonna be at the HAMB drags Desoto? I'd like to run ya.

Oh, the 354 water crossover is the same as the 392.

 

I have a number of 331 pumps, if anyone is interested in spares get in touch. thats a steel 396 pump on my 331.most of the rest of the stuff, adapters, etc. came from Hot Heads. you should be able to get a good idea of the costs from their website.

 

Anyone want to get rid of their old, leaking, original water pump? I would like to get a few and try my hand at rebuilding one or more...

 

How about two 55's when I bought the 396 chevy pump I asked them for the air condition one (larger impeller?)

 

I hear waht you were sayin, And at first i was just trying to say that there wasent that big or reason to start switchen a bunch of Chevy parts onto yer Hemi.

But it appears everyone else is doing it so i should re~cant what i said & let you do what you want.. no biggie to me.

My hemi runs between 145 on a cool day and has never been over 195........ But who am I to go against the masses.. I just think a Hemi looks best with its original parts in play.

 

how much did the pistons set you back? or did you just find them one day? thats the biggest thing on these old hemis that needs the most attention is the compression...its abyssmal in stock form.

whered you score the generator at too? im having a tough time finding 12 volt models.

 

440source has new HeavyDuty 361/413 truck waterpumps on their site, see pic below, which "looks" pretty similar to the Hemi-version.
Perhaps these could be made to fit fairly easy on the Hemi-pumphousing?
(although looking at the pics I get the impression the Hemi pump is slightly larger)

 

I gess i broke the rule's by using a chevy water pump. Not to mention the pontiac rod bearings , the olds rod bolts and chevy valves and wrist pins.

 

Sounds like your Hemi is made Ford Tuff with GM stuff.

 

I run a stock pump on mine, not worried about the extra weight 'cause I got the HEMI to move it. The pump on the car is a "GUARANTEED FOR LIFE" pump from Kanter, cost me around $110 a while back. I keep a stock spare in the garage, so if the lifetime one fails I have one to use while Kanter ships me a replacement.

 

I have 3 sets of JAHNS pistons for DeSoto Hemis .... Not one set cost me over $300.00.

12v Generator was purchased at a rebuild shop near me.. They arent tough to find.... 12v generators were on every thing from the mid 50s to the mid 60s.

SEE, THE THING IS... IF YOU DO YOUR HOMEWORK AND ACTUALLY LOVE WHAT YOU ARE BUILDING YOU WILL SEEK OUT COOL SHIT AND MAKE IT THE BEST LOOKING AS WELL AS RUNNING.

 

YER A FUNNY GUY , Kerry !!

You think this Hemi Sport Coupe is all i have to work on ?

You think i dont make or modifie my own parts as well ?

Being Broke has nuthing to do with Chrome, It has to do with the the fact i am building a 1927 T Roadster Pickup with a flathead from ground up for my daughter.

Also has to do with always gathering parts for other projects such a '57 Pontiac powered '31 Ford Pick up, A 1957 Pan Head Harley, & a '40s lake style 1927 Nash Roadster with a flathead Cadillac.

Not to mention the up keep of my '55 F~350 dually parts chaser, '55 F~100 chopped top Pontiac powered 1/2 ton & my daughters '61 Mild Custom Ford Falcon..

OHHH I forgot to mention the '61 Dodge Seneca with a 440 3 carbed Chrysler in it.

I guess maybe, just maybe, I am not up to your standard of what a HAMB APPROVED HOT RODDER IS !

The HAMB didnt make me what i am today, been thru many different styles & era's of cars .... Ive been around this hobby for many years, i aint new to the game, But i do see a decline in what this site is supposed to stand for.

PREACHING THE GOSPEL OF TRADITIONAL HOT RODS & CUSTOMS.

LOLOL YEA, RIGHT !!!

 

Ya know what Guys ?

I dunno why i even let some guys like Kerry get my Goat over such things, I Like cars & builders that take Pride in trying to make a car like it ACTUALLY came from a period in time.. 20s, 30s, 40s, 50s, 60s .... Whatever

I have been told my Sport Coupe is Really well done, I know its fast a fuck, I know i do my best to utilize a vast array of VINTAGE parts so that makes me feel good.

I also know i rasied 2 kids while doing this & my daughter is a Young Hot Rodder, Jus a Low Life Oil field worker that dont make alot of $$ and even less for the past year due to an accident & knee surgery 4 weeks ago.

And the fact that i am a FULL TIME car guy, daily drivers at my house are my '55 dually & a '61 Falcon..... No Import dailys to drive to the office.

So, just a note to the guy who started this thread, I didnt meen for it to go this route, but it always seems to when a TRADITIONAL Hot Rod guy makes a statment in a post about "NEW PARTS"
Go which ever way you like, Dont make my DeSoto look any different.

 

I wasn't bagging on you. Just trying to defend myself. Sorry now to have wasted the bandwidth.

 

Actually, the pump pictured above has a slightly larger 5-bolt pattern than the 392 pump everyone has a difficult time finding. Although it looks the same, I put one I have up to a 392 housing and saw it won't work. Really sucks since my 361 pump is rebuilt, too...

 

It took 11 fucking posts to figure this out? And chevy pump guys are the slow ones?

 

DeSoto, I think THAT is the disconnect here. I believe the "mission statement" (so to speak) isn't about "PREACHING" --- I believe it says "SPREADING....." And while that may seem insignificant I think that's at least part of the issue you're having with us heathens (just kidding) but seriously your comments about "pissing in the wind" and others aren't those that tend to influence people, but instead increase the gap in opinons.

Frankly I agree with you (on some points) like a traditional car with appropriate vintage parts adds a certain something to a hot rod. That too can be taken too far. Does anyone really need 1200 dollar headlights or ten thoussand dollar brakes. Granted I knwo you haven't suggested any of those ridiculous things, but just trying to make a point.

When I first got into 392's there wasn't any such thing as Ebay - we hunted parts the traditional way - SWAPMEETS!!!! In those days 392 stuff was strictly yesterdays news - they were "pigs" barely worth scrap - except to me - I grabbed everything I could get my hands on. Shit back then I couldn't even buy a friggin camshaft - had to send mine out to ISKY to have it reground (they do killer work BTW)

I have a couple 392 powered cars - some I wouldn't ever dream of putting a chevy water pump on - another I wouldn't hesitate. The notion that I am a dial 1-800- send me the parts hot rodder couldn't be the further from the truth.

Anyways my long winded point is that you might have more sucess convincing us by being a little more easy going. Preaching with insults sprinkled in your sermon isn't really a formula for sucess.


I've been told many times that my posts come across much harsher than I intended -so truely I make these suggestions in the spirit of helping not trying to be a smart ass.

 

Wow, I have never had a thread go this far! Too bad that the majority of this tread has nothing to do with my original question. Just wanted some info from others that have had some personal experiences with this modification. Looks like just a few are interested in sharing knowlege and the rest are interested in their ego. I would like to see nothing more posted to this thread unless it directly relates to the questions I posed in the first post...If anyone feels they have something to add that is outside the scope of my original post, please start your own thread about whatever it is that you need to prove. Get over it and focus on what is asked, if you cannot, move on to another thread.

 

On my 354 I run the bbchev waterpump via the hotheads adapters, on the stock timming cover you have to cut off the bump for the fuel pump and weld the hole shut. It has to be flat for the waterpump to fit. The cross over is a 392, the harmonic balancer is a 340 with a bigger key way and timming tape. Pulleys are also new from PAW. hope this helps

 

I've got a '54 331 in my car with an aluminum front cover and annaluminum SBC water pump. Best thing I ever did. period. Hope this helps.

 

I am looking for a measurement from the block face (surface timing cover bolts to) to the fan. If you have such measurement , let me know what type of pump you are using (long or short) and type of adapter. I am looking for a few more inches up front on my '30 Dodge and hope not to recess the firewall. If I do the conversion, I would like to do it with a long style pump, but don't know if there is any space advantage to the long pump over stock set up. I will use the original timing cover unless there is no space advantage, then I will modify the cover so as to use the short pump. Either way, I am looking for measurement with both style of pumps.

Thanks to those that have provided usefull info. regardless of what your religion is.

 

HHH spacers, BBC Short, 7" from the block to the end of the pulley shaft...sorry dont have a fan yet.

 

I agreed with the first post you made, and a few parts of the second. But it has become obvious that you are just planning on using this thread to tell us how cool your car is because you built it with some old parts. Telling us how awesome your car is is kinda lame.
