20's Dodge OHV conversion info WANTED.

An oldtimer that I know says that he saw an OHV conversion for a 20's Dodge 4cyl along time ago at the Hershey swap meet,he did not buy it because it was incomplete .Does anybody know anything about this conversion or who made or where I can find one ??

 

I've got a sales brochure, will post a photo as soon as I find it.

 

Someone mentioned that to me once. Didnt give any info though. I'm interested now , hope someone has info/pics!!!

 

WOW!! Cool. I cant wait!!!

 

ok, Found it, the Morton & Brett Blue Book of Speed, January 1929. Hope these photos are readable. I think Speedy Bill has one of thes heads in his collection.

 

WOW!!! Thanks! Were they the only company that made one or were there some others??

 

Same Morton & Brett head but in a larger sales brochure.

 

Most of the speed equipment manufactured in the 1920's was for Model T Fords. If you collect the speed catalogs from the era you'll find that they all used the same illustrations in their catalogs so it is hard to say who made what. There may be other Dodge heads out there I just don't have info on them. Funny, today I stoped by to see a guy about a Fronty on a T block, just want to keep him aware that I'm the guy to call when he is ready to part with it. Glad there is a renewed interest in banger stuff her on the HAMB!

 

Now........... Thats gonna be REALLY hard to find!!

 

You said it brother. It would be well worth the hunt, but the price is another story. 'Bout the same as a Miller twin cam.

 

Hello everyone,

I'm from southern Indiana, and recently found this forum while searching for Morton & Brett heads & engines.

My only old vehicle is a 1926 Graham Brothers/Dodge fire engine. It has a Prospect (Ohio) Fire Equipment Co. fire truck body, two chemical tanks, and a Deluge rotary pump.

The truck's engine had been replaced with a 1970s four banger before I got it. It did come with the old engine and transmission. I don't know anything about their condition. Restoring and reinstalling them are included in my retirement plans, nine years in the future.The engine has a cast overhead valve cover that says Morton & Brett, Indianapolis. I have read that they made heads for a lot of engine manufacturers and even made Indy cars & engines. Also that they made a conversion head for Dodge Bros. engines.

 

Take a look at some of rich fox's newer posts- he's working on a Morton and Brett Dodge head.

One reason that Dodge OHV conversions are fairly rare is because Dodge was a more expensive car- the Model T was plentiful and CHEAP to build/modify.

 

I have heard of those Morton & Brett heads. Made them for Fords also. Roof made a 16 valve head for the Dodge. It was more of a hot motor compaired to the T Ford than most people know today.

 

Sorry Rich, I keep forgetting that you're working on a Roof!


AC1503- Welcome to the HAMB! PLEASE share some pics of your engine- early Dodges have a special place with me AND the M&B head is a rarity!!!

 

You could always find a V8 that has the same bore centers and use one head. Probably easier would be to use an overhead cam motor so you wouldn't have to mess with the pushrod geometry. What is the bore spacing on the early dodge 4 banger motors anyway?
I was looking into those for a possible V4F bonneville car.

 

Mac- No you were right the first time. I have a Morton & Brett to work on. The guy who actually ownes the head also has a Roof 16 valve but I didn't want to fool with something that rare and absolutly virgin as his.....Finding a V8 with the same bore spacing may not be easy as V8s that I have seen have a concictant bore spacing. As you can see in the M&B picture above the Dodge has a quite different spacing between 2 and 3 than between 1 and 2 or 3 and 4. On my Plymouth I chose to just ignore that I had 4 seperate combustion chambers when puting a Ford head on the Plymouth block. You may find it difficult to fit the V4F rules with an OHV head anyway

 

I believe Earl Edgerton is making a contemporary one that folks have run at Bonneville. Edgy spees shop

 

Earl made ONE flathead for the Dodge Bros. for his friend Pete Hendrickson's Bonneville roadster. When I inquired about ant more of those heads Earl said No. But you never know what may be comming out of his shop.

 

If you look down in the right bottom corner of the brochure it says there were TWO heads available. One for street and one for racing, I'm guessing with differant C.R. Anyone know anything about this?

 

Rich, this sentence caught my interest and made me curious.
Can you elaborate ? thanks

 

Because of the differance between the bore centers on the Ford head and the Plymouth block as well as the Ford chamber being much wider than the Plymouth bore, the valves position relitive to the bore was different on each cylinder. Exhaust pretty much over the bore, intake half over the deck and so on. But it ran.

 

I don't know why I put the F in V4F maybe i was thinking fuel instead of flathead.

 

I hope that I can eventually restore and reinstall the engine & transmission in my fire engine, to get it back like it should be.

 

If I can be of any help please feel free to ask. Although 9 years may be streching it some.

 

AC1503,did I see you post pics of this on AACA forum a while back? Does anyone know was this a common modification for fire trucks?? Maybe I need to start peaking under some fire truck hoods in junk yards. I NEED a M&B head for my DB. BTW, welcome to the HAMB.

 

Peek for me too, Doug
