Well Earl Edgerton does it, who else...

Very Interesting. It appears the intake valves are in the head but the exhaust valves are still in the block. This should make for some very good cross ventilation.

Well, the "F-head" design has been around for about 100 years...

It served Jeep well as an upgrade to the 134 Go-Devil flatty four, creating the Hurricane Four that powered CJ's from the 3-B through the 1970's...

Wonder if Earl makes these for the big six too...

Love his block off plates.. Neat motor. Gotta give the guy lots of credit..

[martybose]

I wonder how they sealed the block area where the exhaust valve used to be from the combustion chamber? I'm assuming that they used a pushrod from the exhaust lifter to a rocker to actuate the intake valve on the other side of the head.

The valve seats were cut out as if they were going to be replaced with hardened seats, but replaced with cast iron plugs instead, then tapped for the pushrods. Then the block was decked.

The truck belongs to one Earl Edgerton's crew, Cris. He had the truck ready for the trip to the salt last year, aside from a few bugs like water leaks, so he didn't bring it then.

The head is 9.5:1 compression, intake valves in the head, exhaust in the block. Cris has the fenton headers piped into one collector pipe and a single muffler with pipe all the way out the back. Sounds mellow and smooth, but unmistakably Chrysler flathead six.

Cris make the intake manifold himself. Very nice craftsmanship.

It was great to stand around the truck at the Nugget gathering and listen to all the "experts" who knew what it was... LOL Not one of them got it right.

What a cool 'ol truck!

Here's a couple more pics-

What is the Truck?? Dodge Brothers, Fargo? Is it a shorty block or long?

[Don Coatney]

Thanks for the pictures and description! I want a truck just like that. Tell us more about your adventure???

[Don Coatney]

Dual point distributor? Breather for the oil fill looks like a carb filter? Carbs mounted sideways with in-line linkage? Where is the connection for the vac advance located on the carb? On one carb or all three? Still running a 6 volt generator? Real patina?

Dodge, but not sure on the year... 1935?

The patina is the real deal... dirt and all. He uses the truck on his ranch, lives miles from pavement. I asked him how long he'd owned the truck, and he smiled and said, "which part"... He's pieced it together over the years, about 10.

Didn't ask about the distributor, lookes like a stocker to me but I wouldn't know the difference from the outside. I can't tell from the pics I took where the vac advance is connected, didn't pay attention to that detail.

All three carbs are working. I think he said the carbs are Pinto before they made the engine bigger, early production something or other. He made an aluminum adapter to mount the carbs, so that if they didn't work out, he could change the adapter to any other carb. Linkage is direct to all three, not progressive. He said the carbs worked perfect out of the box, got lucky.

Dunno of it's 6v or 12v.

Actually Ardun, a German engineer, living in england developed an overhead valve assembly for trucks- garbage trucks for the city of London so the story goes that fit on ford v/8 engines . This became known as the Ardun head.

Also in the 3o's Several folks developed overhead valve systems for A model engine. I actually have a Miller Schofield conversion. It is a 20 ci 32 4 cyl ford with miller Schofield overhead valve system- Said to develop 85 to 90 hp.

Honest to God it looks like a head from a 289 Ford or 305 Chevy- in fact it now uses Chevy valve springs.

Hey Frank!!! Here is a didja know regarding the jeep toronado OHC engine. IKA (Industias Kaiser Argentina) continued till about 74 using this engine in a Rambler American bodied car called the Torino. The Torino 380 (based on the 3.8 litre displacement) featured the 230 Cu in engine, and the 380 special featured three side draft carbs and was heavily raced in Argintina's version of TRANS AM racing series. they were also used heavily in Rally competition.

Up in the bone yard that Shel visits there are a couple mid 60's Jeep trucks with these engines in them. It is a neat looking powerplant.

77 torino later ones were made by Renault. perhaps the start of the AMC Renault Alliance (pardon the pun)

[Tony_Urwin]

Groan......I actually owned an Alliance as a young man. Worse car I ever owned by far. MotorWeek Car of the Year, they said. Somebody got greased on that one!

So your were the other one............

Did you know the rest of the Zora Arkus Dontov story? His is the man behind making the Corvette the performace machine that it is. He designed the independent rear suspension for the Vette, among other things. His Dontov 30/30 cam has been a staple of hot rodding for decades. Quite a career.

There is a great excerpt from a new book about him in the current Rodder's Journal. Worth picking up a copy.

Pete thanks for posting that. I thought he was one in the same guy. This would be a neat engine to own.

[Young Ed]

And the car it was in just for fun

[De Soto Frank]

Greg,

I didn't know that there was a non-Ford Torino... much less with the

K-W "Tornado" six...

A buddy used to have a '64 J-100 step-side (that's right, a step-side J-truck!), with the 230 OHC engine... I still had my '61 Utility truck ,and it was interesting park the two side-by-side and compare and contrast.

That 230 OHC Jeep six was a torquey SOB, and ran great; the two big issues with it was oil leakage around the front mounting plate behind the timing gears) and the tendency to crack exhaust manifolds...

I think it was based on the 226 Continental engine that had powered Kaiser-Frazers and Jeeps from '53; it was a true "hemi" head...

Would love to see something like that on an old MoPar six!

[greg g]

Funny how some problems stay in the genes. Both of the cherokees I have had with the 4.0 six exibited exhaust manifold leaks. the current one with 99K on it leaks till it get hot, then the leak seals and quiets right down. the first one had a long crack in along the manifold that kept getting worse.
