Carb model G vs NH

[24ruxstel1339]

I have a NH carburetor on my 24 now.
I have a model G on an aluminum manifold, both very nice.
I also have a Wilmo exhaust/intake one piece manifold on it now.

Any thoughts about swapping to the aluminum intake and the model G or is the NH a better setup ? I have several exhaust manifolds to use.
I also have a higher compression aluminum head I will put on at the same time.
Would you polish it or paint it ?

The NH would be proper for your 24 as the all new NH appeared during 1920-1925. The G would be for a 1914-17 T for show.

The NH is the "go to" carb for a driver, my 26 fordor had the vaporizer system that had been used on the fordson tractors since 1917. I now have an NH on it now.

My thoughts on aluminum heads, they look great on a flathead in a hot rod

Both carburetors will serve you well. The Holly's are trouble free. If the head is finned, I would polish it. If it looks like a stock head, I would paint it.

My PO; If the head is higher compression I would go with on of the made for Model T Strombergs and use the aluminum intake. I am not a fan of the NH's anyway. While they are easy to work on I personally, with some experience, think they are over rated. While I have not used the Holley G, it is reported that they are a better carb. Me I like the Kingston L4 and have used in the past; Kingston L4, Marvel (before they combined with Schebler) and Schebler carbs. You might also consider the Simmons straight thru.

Good stuff y'all.
I have to look and see if there are any other carbs around.
I found a box full of A carbs. Not sure if any Strombergs exist in the cluster**** of parts I have.
Obviously I have to run a side draft with the gravity flow tank under the seat.
The head is stock looking, even has the Ford script, still pondering paint or polish. Also is higher compression, had one on it before, but it froze and cracked the winter after my dad passed. Heater was malfunctioning and I realized a little bit late. I put a stock iron head on for the meantime and it's a noticeable difference in hill climbing power.

I'll get some pics later on.

This is the current Wilmo/Holley NH setup.

And the G with the aluminum manifold.

Jenson aluminum head with much less combustion chamber area

I guess I'll need to resize a couple pics...

Let's try this again...
Wilmo manifold

Combustion chamber side of the head.

And the distributor that I presume is a Kent.

Cool head. I would bead blast it, look for cracks and have it checked and surfaced if/as needed before using. Not milled, just cleaned up.

Distributor does not look like an Atwater-Kent, it looks maybe newer then that.

After I got the radiator off, turns out to be a Thomas distributor !!

The head looks pretty good, I'm a po boy mechanic.
A good cleaning with a 3M plastic bristle disc then check with a straight edge and if it's within a few thousandths...on it goes.
I'm leaning toward matching the finish of the intake, shiny and all that.
I have a lot of paint work to do to the engine and the front end, no restoration, but a good touching up.
I was going to have a friend who has a radiator shop fix the radiator, but I think I can do it.

 

[24ruxstel1339]

Got it pretty much torn down, degreased and some more sanding and then touch up the engine and front end. I decided I will shine the aluminum head and swap it after painting the block.
Probably go ahead and lap the valves, I do recall, the old man put flathead V8 valves in it and a Victor gasket is the only one that will clear.

I left mine natural aluminum. I just finished this motor with a Winfield SR. This is a good running motor. I've been running this Stromberg OF for several years now in my Roadster and it runs real strong. I ran a Simmons straight through before and they are an improvement over the NH. The NH is a good carb.

 

[24ruxstel1339]

I got it back together enough to start, still need to fix the radiator.
Model G carb ran, but started leaking....I cleaned out the NH and put it back on.
I didn't lap the valves, but did adjust them. While the head was off, I cranked it over and it was visually noticeable, some of the valves were not opening enough.
I set them at .012"I and .014"E. Do you think that's too tight ?
I found what looked to be a new exhaust manifold and painted it with stove paint. Just cleaned the head with a whizzy wheel, I will hand polish it a little, just for protection from corrosion.

I set my intake and exhaust at .010", but i'm using small block Chevy valves. They expand less that stock T valves.

What stove paint did you use on your exhaust manifold? Looks good.

This one has early V8 Ford valves...

Thanks, It's called Derusto... I put it on with a sponge brush. It was 90 degrees yesterday and I set it in the sun for about 4 hours after 2 coats. It was dry and flowed out pretty nice.

 

[24ruxstel1339]

Took er out, got some gas, long way around the block.
Running much better, pulls hills a lot easier.
Stove paint on the manifold came off like a banana peel...

I have both carbs and run the NH. The NH is so simple to clean and set up and it has been very reliable for me. My car is a 1914 Touring and I should be running the G! From what I remember of the G is that the float level is harder to set and get it correct. For me that are a lot of other things that can get me in trouble on the road and with the NH I feel it is just one less headache! Ed
