View Thread: Ford Performance Vehicles Australia's 290 Boss V8

Enano Siniestro
From Ford Performance Vehicles Australia (

I was reading on the engine used by the FPV GT, GT-P, and Pursuit. Awesome power for a naturally aspirated DOHC V8. About equal power as the Cobra, but sans supercharger. Here's the car, and the info (kind of long, but good reading):

"Introducing the Boss 290 powerplant

Race-bred quad-cam multi-valve technology combined with traditional high-compression V8 muscle. The best of both worlds. The awe-inspiring Boss 290 is a power plant unlike any ever built in this country and comes to life on Australia's only current V8 production line.

The Boss 290 was developed right here in Australia by Ford Performance Vehicles for our unique requirements and to meet the rising demands of a new breed of Aussie V8 drivers.

Its 5.4-litre capacity, 32 valves and double overhead camshafts per bank therefore work in concert to release 290 kilowatts of power and a phenomenal 520 Newton-meters of torque. So not only is there free-revving top-end power but a wall of torque from down low as well. In combination with the tuned stainless steel exhaust system, it produces the trademark rumble that lets you know you're driving a real, blue-blooded Aussie V8. It has a quality that clearly communicates who exactly owns the road.


A revered name has returned: the Boss is back.
Ford buffs know that this name was first used on a special engine fitted to the 1969 Mustang - the Boss 302. This revered engine shares many uncanny similarities with its modern-day heir. The Boss 290 delivers 290 kilowatts (389 hp) at 5,500 rpm, the same iconic power figure in kilowatts the original Boss 302 had in horsepower along with the first XW Falcon GT 351 on its 1969 release. It also shares the same compression ratio of 10.5:1 with the Boss 302. And the 520 Newton-meter (384 lb-ft) torque figure launches the new Boss 290 into a class all its own.

To fit the Boss 290 into the new GT, GT-P and Pursuit without compromising ground clearance or stifling airflow, a special power bulge bonnet was factory-designed and tooled, creating a new level of authority on the street.


The block is cast-iron which makes it exceptionally rigid. It is three times stronger than aluminum for extra durability reserves and refinement under high horsepower and torque loads and maintains tolerances better. Cast-iron is more stable over a wider range of temperatures and there is less movement at critical sealing points for superior resistance to oil and coolant leaks. Ultimately, it's what we use for V8 Supercar engines. Enough said.

The engine has an under-square bore and stroke ratio that delivers the flexibility, fast response and strong pulling power from low engine speeds expected from a high-performance V8.

A forged steel crankshaft maintains strength and refinement under high power and torque loads.

Each crankshaft undergoes a special balancing process at Ford Performance Vehicles prior to assembly to match the special Boss 290 piston and connecting rod combination for exceptional refinement and reduced stress on components at all engine speeds.

Locally-sourced high-performance tri-metal main and big-end bearings are specified for extra durability under higher engine speeds and peak power and torque loads.

Each main bearing cap is precisely located by two cross-bolts, two vertical bolts and two vertical locating dowels for superior location over six bolts. That means superior durability and refinement under high performance loads.

Each connecting rod is re-engineered to match the stronger pistons and floating gudgeons.

The connecting rod big ends are separated by a controlled cracking process before main bearing insertion. When reconnected, this creates a multi-ridged join unique to each connecting rod that is exceptionally strong and virtually invisible.

Locally-supplied high-performance pistons with domed tops lift the compression ratio to 10.5:1 on 96 RON PULP for improved engine response, efficiency and fuel economy under light throttle loads.

The oil pump is driven directly off the crankshaft. So when the engine is running, the oil pump is too. And that eliminates one serious potential for engine failure (for example, when a separate oil pump drive breaks and the engine continues to run).


Twin overhead camshafts per bank with four valves per cylinder to produce a deep-breathing, high-performance engine for exciting and consistent power and torque delivery right up to the red line.

The heads are cast in aluminium alloy to minimise weight and to reach the optimum operating temperature faster. They feature an improved Cobra R design with a straighter, better-breathing inlet port.

The camshafts are hollow for reduced weight, less inertia - and faster response.

Sealed, high-quality timing chains are lubricated by the engine's oil supply for long life. That means a major reduction in maintenance costs compared to timing belt replacement and eliminates the potential of engine damage through a missed belt change.

For critical engine joins, special high-tensile bolts are stretched under torque for maximum strength and extra resistance to loosening.


The inlet manifold is manufactured in Australia with tuned length trumpets to match the straighter inlet port of the latest head design for strong torque at lower engine speeds, accessible power at everyday speeds and deep breathing at high engine speeds.

A 75 mm throttle body with drive-by-wire linkage eliminates the noise and vibration path that a mechanical linkage generates as it enters the cabin.

The Boss cast-alloy plenum cover is made in Australia to meet the engine's specific deep breathing requirements without compromise. The Boss bonnet pressing was tooled to accommodate this design.

The Boss low-restriction air-intake system was developed and manufactured in Australia and incorporates the conical filter element from the Mustang Cobra. This optimizes the airflow to the inlet system.


The stainless-steel exhaust system was manufactured in Australia to reduce weight and generate a deep, resonant engine note.

Build Process

The new Boss 290 engine is meticulously assembled by hand at Ford Performance Vehicles on the only V8 production line in Australia.

By building our own engines, rather than importing a fully-assembled engine developed overseas, Ford Performance Vehicles retains ultimate control over the development of engines to answer the unique needs of Australian performance car enthusiasts.
To deliver the solid muscle at low engine speeds that Aussies expect in a high-performance V8 while maintaining the free-revving, deep-breathing feel of a thoroughbred sports engine, Ford Performance Vehicles has developed a unique engine that has no equivalent in the Ford world.

The former Tickford engine building facility at Campbellfield has just had a $1.5 million assembly track specifically installed for the production of this new engine.
On this space-age carousel, manned by technicians who previously honed their skills hand-building the previous Windsor V8s, each Boss 290 engine is painstakingly assembled from bare blocks and heads.

A pristine environment, our assembly line has more in common with a surgery than a factory. Indeed, to see our technicians huddled over an engine is truly reminiscent of an operating theatre. The latest computer-controlled dual-nut runners are used for the critical fastening and torquing of the heads, connecting rods and main-bearing caps. Far more sensitive than manual tightening, they are programmed to react instantly to faults in materials and parts, sending an instant alert to their operator.

As a result, the new line has enabled Ford performance Vehicles to adopt the latest best practices for our industry not only in quality control but occupational health and safety too.

As a measure of the efficiency of this approach, the next cheapest quad-cam V8 you can buy fitted to a four-door sedan is the Jaguar S-Type at $112,000. Incidentally, that is a smaller and less powerful engine. For comparable outputs from a similar V8 engine, you'd need to spend around $200,000 (Australian Dollars) for a premium European brand."

Great info :cheers:

Wonder if they'll send me one of those?

I like the fact that they get about as much power as the Cobra, from the same engine, without a supercharger. Then think what this engine could do with a supercharger. Sounds like a good candidate for the "Ford GT Version R".

Great read Enano!

That is one badass engine that they put in the Fords in Australia. 390 hp without an s/c or turbo is pretty damn amazing. With a few mods, Ford could be talking supercar #2.:humpy:

Yeah, kinda like 405hp without one. ;)

Cool car nonetheless. Why doesn't ford give us a performance car with a useable backseat here?

No demand...or so they think.

Carlos Carrera
yeah almost as good as a LS6. :D

Carlos Carrera
i was wondering...
wich type of engine its better.. in reliability.
This Boss and Ford 5.4 engines
or LS1 and LS6 GM engines?

Carlos Carrera
wich is the weight on that Falcon GT, and price tag?

the HSV 300kw Coupe GTS its 96K aussie dlls.

Why do I shiver when I read this quote? Is it that it is true, or that the mantle of makers of great V-8's have been wrestled from our graps by the Aussies?

Makes me kind of :curse: that we must look elsewhere and drool over V-8 powered cars, made by none other than American companies. :banghead:

Carlos Carrera
the Aussie V8s of Ford and Holden are exactly the SAME as the triton 5.4 and the LS1 5.7 from US?

But they have them in more cars down there. That was my point, sorry if it was muddled.

Enano Siniestro
Ford did pretty much the same here with the 5.4 DOHC Triton. It was called the Cobra R. But the price of admission was too high. That's why they went cheapo and used a supercharger with the new Cobra. I would rather have an all-motor V8 with that kind of power, and Ford Australia offers it in more models. Their V8 Supercar series is what NASCAR should be: RWD, V8 sedans that are actually available to the public, and with the same layout. The grass is looking greener in the land of Oz.

Same here. I mean, if I can read the menu at the local Outback Steakhouse, I should be able to speak like an Oz-tralian, right?

I never can make it into the right bathroom there though :nope:

yep... I own one, mines white with blue stripes 5spd manual

F***ing sweet

Sia Bani
Nice! What's it run?

Badass!:badass: I really like Ford Australia and wish they would bring those cars to the US but it wont happen.

The S-one-W
while I am a huge fan of the 4G63 I really dig that V8 sound. I wish the US had the same cool cars and motors that the rest of the world probably takes for granted
