V8 Waterpump - hose?

[SUHRsc]

Aside from any opinions on the necessity of this change... I am putting a V8 waterpump on a Model-A. I am building a dirt track racing roadster and this just looks a little more racey, plus I got it as you see it... fresh and ready to go... pretty cheap!

So, with that aside. If anyone has done this conversion. What did you do for a hose connection?

I could cut and reshape the radiator neck to angle downward but I hate to do that if I don't have to.
I'm really not seeing much of any other option though aside from a goofy looking hose that bends all over and changes size, to fit.

thanks for any help!

It's a quick easy mod for a radiator shop.
Take the picture you have here along so they can see what is needed.

Thanks Pete,
I think I can just pie cut and reweld the radiator neck to match up.

Just sort of wondering what others have done, possibly without modifying the radiator?

Thanks

Slightly out-of-the box thought: If you don't mind a few late model parts, get a '33-4 B front cover and crank pulley and move that thing back about an inch for a custom fit.
I'm not worrying about the spacer because I know you can weld or machine anything. With an inch out of there, spacer could be made from a solid block of metal and some countersunk head bolts.
Hmmm...what would a '32 pump look like once the thing is moved back? I think it would be a neat fit, but probably too little hose to absorb movement.

Thanks Bruce,
That's a good idea!

This is the "clone" of my family's racecar from '47-'48.

Here you Zach! bottom of page.

Edit: oops, not entirely what you need. Saw your picture just now.

Hey Zach, I'm in the process of working through a similar setup - only with a '32 "B" radiator shortened 4 3/8". Modifying the radiator inlet is the easiest way as far as I can tell.

As your radiator has a little more height, you may be able to get away with cutting a couple inches off the end of the inlet, then bending a hose to fit. You'll want to get a piece of 1 3/4" hose to go over the V8 pump outlet to act as a bushing for the 2" hose that will slide over the bushing and go up to the radiator.

Here's a photo'chop' of what I'd do - given your setup;

thank you G white. I looked into swapping to B parts but looks like more work then I want to do right now... so I sliced the neck off at an angle and then rotated it 180° so that it angled down more.. TIG brazing (i guess its called?) with copper filler wire, these radiators have a steel neck on them. Cooling it often with an air hose. Seems like it'll work out.

Good news is... all supplies showed up so hopefully I can fire the motor in a few days. Its brand new and needs broken in. Getting anxious to hear it run!

thanks everyone for the help and advice

When I set up the Gordon-Smith compressor in my avatar, I was having problems with the radiator - which is a 1928-29 radiator - using it against the 1932 three bolt waterpump. The 1932 pump outlet is even a bit more forward than the tall 1930-31 Model A pump outlet casting, plus I had the early radiator. Like your situation above, my alignment just wasn't right.

I was getting close to buying one of those "corrugated" hoses which are commonly seen as a "universal hose." But then I had a thought.

Radiator hose comes in all types and sizes of "pre-made" hoses. I went out and looked at my (then) 1995 Chevrolet C1500 pickup - with a V6 engine - and saw a "bent" hose which could be made to fit: right diameter, a dogleg bend about 8 inches in from one end at about 30 degrees.

I went to the auto parts store and showed him on the diagram. I bought the hose I wanted - brought it home - and cut off the excess on the bandsaw. I think the hose cost like $8 then.

Voila - perfect fit for the Model A air compressor.

If you nip off your radiator inlet neck a bit - the same technique could work for you.

Edit: I see you've done that.

If you are dirt racing , I would think a flexable hose would be best .

If its rigid something will give .

Years ago I thought the same thing until a very wise older mechanic told me the flex hose comes straight and is always putting pressure on each end since it's always trying to be straight. I thought about it and realised he was right, so since then my first choice is to find a correctly formed hose.

Sweet, post up some pics!

[hardtimes]

So, where's the pics of the entire vehicle ? That half engine pic is a teaser,eh !!

[SUHRsc]

Not exactly Fordbarn appropriate... but... it is mostly all Model-A...

So here it is a year or so ago, before I started really digging in to get it on the track. Going to have quite a list of modifications by the time it's done. As much as possibly will be 1948 correct which is when the original car raced.
The paint in the photo is how we got the body. It will be dark blue in the end as the original was.


This is 1948

The 1948 pix gives it the ultimate license to be here. In fact DON'T show it over there at HAMB. Let them come here to see what a REAL race car is like.

This here is what they're all trying to copy over there.

Pretenders to the throne.

Kidding - but only a little.

That's neat!
Here's mine in 48 and now.

Pete, very cool to have one with real history! Mine is strictly a recreation. Nothing on the car is from the original. It was built and owned by members of my family and driven buy a local guy named Mitch Smith, who went on to be a very famous local sprint car driver. They had a 2nd car number 45 that my relatives actually drove. A cut down '35 Ford cowl on a chassis with 2 hoops and some tubing from front to back.
I actually think that my modern version of the roadster will be a little hotter then the original was. It will also get a wagon wheel hoop roll bar at the back of the interior. I have 4 total photos and one has the roll bar. I found an original rule book stating that it was mandatory when a new organization was formed in July 1948 to sanction the racing.

Thanks much for sharing...great stuff !
'not exactly appropriate'...HA ! Better looking than my '30 roadster and more appropriate too ...as in better paint !
