The production of vehicles in Argentina by Ford, powered by V8 engines always was based on 292 Y-blocks. 50`s cars and trucks imported from USA were equiped with original engines. Vehicles from normal production(trucks at earlys 60) was equiped with Y blocks, some imported 312, 368 and some 352" FE`s. Later, Y-blocks became standard and only V8 engine that Argie Ford put on it`s vehicles. In 1969 ford introduce a 4door sedan called Fairlane, Know in USA to carry a small blocks and FE`s engine. But Ford introduce that car with an Y-block on current production for F100/350/600 trucks.

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.
