During 1966, Argentinian Racers were working with many inventions to give your cars more power. Based on a technical race rules and some parameters, Ford in conjunction with ford racers develop a design based on 289" small block heads. It was basically an Y-block with Small block heads and cam with sball block firing order and small block intake and exhaust ports order. Also was reduced on displacement to 4 liter(maybe 240") Reach the scary amount of 320 HP.

On 1969, Ford decide to make the mod to Y-blocks impulsed by results of that modification and some excuese about the bad an small space in the fairlane engine compartment.

The results was called "fase 2"(phase II) Then people star to call "fhase 1" to the original 292 desing.

The diferences are:

-New head desing, based on 289 heads with same valve order(I-E/I-E/I-E/I-E) versus original ford design or fhase 1 head(E-I/I-E/E-I/I-E)(I=intake, E=exhaust)

-Because the head, the cam was a new design based on the Small block order.

-exhaust manifolds was made same as 289 xhaust manifolds as seen on the pic.

Other changes was the relocation of the oil charge tube, you can see it on the pic, located on valve cover.

Argie engines on stock condition always was the same 2, only variation was the type of oilpans(fortruck or car): compression ratio(7,1:1 for trucks and 8:1 for Fairlane) by changing pistons(dish, flat and a late version of dome pistos); electronic ignition; diameter of valves(smaller for trucks an larger for cars and F100 post 80`s) and the same 2 barrel holley carb.

Later I`m going to post a traslation to english of the making of that engine thatwas the inspiration for the argie design.

Very interesting, I have always wondered about those engines.

One question with the cam and valve arrangement change is, Did they always stick with a solid mushroom lifter or did they make some blocks with drop in or hydraulic lifters???

the other big question is what ever happened to the molds for those catings??? It would be nice if they were dug out of the rubble somewhere.

Thanks Billy & Ted for your interest.

The same mechanical lifters remains on Phase II engines. Same rocker arms configuration too.

Moulds are at original foundry buildings, they made a set of 50 pair by year for some parts dealers, but they make it on cast iron. It would be better if they  make it on aluminum. We must wait for some miracle...

I think the argentina heads would be well worth the shipping money, should someone decide to go get some!

No, but seriously, if you look on youtube.com, & type in Y block, you can find some short videos of argentina y blocks being run.  The sould of the engine is definetly a cross breed of the loveable Y, & a small blocks snappy response.

Some rebop heads would be in high demand!  would be much better than plain alum. heads with semi improved ports.

It's only money right??

There is a pair of them in the US.  One was at EXPO 3 or 4 years ago, for the life of me I can't remember who brought it.  He had brought them from Argentina.

At the time we sort of passed over them, camshaft issue mainly.  Now I'm sure we could get a windsor cam made with Y sized journals, use a belt driven oil pump and crank trigger ignition.  Or import Argentine blanks and have them ground to profiles we want.

If you are interested on a pair of heads please let me know.

Here is another friend of mine, from Buenos Aires, George(Jorge) signed as Ford40Deluxe

whats wrong with aussies ?

Production head and block molds are made of silica sand and resin binders in 'hot box' core machines.  (Click on the link to see a very small core machine)  Noticed the parting lines on a head?  Many stacked core molds comprise a cast iron head.  It is an intricate one-piece manifold for air, coolant, and oil flow.

The same hot box will make each core at different times by changing mold tooling.  Cast iron has a much different overall shrink than aluminum.  That means, aluminum molds require different dimensions, made by a skilled Mold Maker.

Sand molds have a short shelf life, are fragile, and must be kept arid.  Ford dips their cured sand molds in Refractory 'Paint', and bakes them to extract ALL moisture just before casting.  Doing a run of fifty heads means hundreds of core mold components waited for the last core pieces to be made.  When iron is finally poured at 3,000*F, each sand mold breaks down, is poured out, and washed out of the casting.

If you ever experience molten metal poured on trapped water, you will NEVER forget it.  When the steam explodes, the earth under your feet ROCKS, and molten iron flies in every direction.  First, it knocks you down because iron is heavy, then it burns immediately.  It's safe to pour water on molten iron, but never pour iron (or slag) on water.

I went through this for a better understanding of why they don't just make heads (or blocks) out of a different metal.  Even the machining phase is different; aluminum heads need guides and seats inserted, and usually go through a LockTite process because of metal porosity.

How did you include actual photo in description instead of as an attachment?

Picture posting instructions  

I’ll add that pictures straight from a digital camera are typically too large to upload directly to the site without first downsizing them.  This site barely tolerates 600X600 pixel sizing when using a host site and while 500X500 is this sites upload maximum, smaller than this for any picture is preferred from both upload and viewing speed standpoints.

Shaft rockers with a solid lift cam but a different firing order.  Intake is definitely different.  Here’s a pic that Anibal posted on the site awhile back showing the intake on the Argentine heads.

Those heads was designed for some race engines back on 70´s. An actual governor(or governator? oh, that´s Arnold! ) Of an Argentina province and a Former Formula One racer, Carlos Reutemman, has some races with a car with these heads.

An Argie mechanic/designer/racer called Heriberto Pronello has a set of that heads. I will try to obtain some info about that heads and that person.

the builder, "tandil" something, now Ronicevi or tandilbert don´t want to build it again. even if a big quantity.
