This is the Ford 5.2 XS Aluminator crate engine, it’s a 580 horsepower V8 with a displacement of 5.2 liters, and it’s made up of a slew of high-end parts used in Ford’s modern Shelby GT500 and GT350s.
📌 The Core Development
The 5.2 XS is the latest version of the Aluminator series, so named due to their aluminum blocks and heads, and for the fact that many of their internal parts are made from high-tech aluminum alloys.

🔍 Background & Sector Context
Ford Racing debuted the “Aluminator” engine at the SEMA Show in Las Vegas in October of 2007. It was a new line of 4.6 liter aluminum crate engines sold as long blocks and short blocks, with short blocks starting at $4,500 USD.
The Aluminator name has since followed Ford’s overhead cam V8 from the 4.6 liter Modular engine to the 5.0 liter Coyote, and then to a 5.2 liter cross-plane relative of the Shelby GT350’s Voodoo V8. Every version of the Aluminator has been sold as a crate engine through Ford’s parts catalog and none have ever been fitted to a production car.
📊 Industry & Real-World Impact
Ford’s Modular V8 entered production for the 1991 model year, and the first Aluminators were built around the aluminum 4.6 liter block from the Mustang GT, a version Ford said was stronger than any of their previous production 4.6 aluminum blocks. The naturally aspirated DOHC long block displaced 281 cubic inches (4.6 liters) and had a 10:1 compression ratio.

It had a forged steel crankshaft, forged H-beam rods, and forged pistons sitting under 2003-2004 Mustang Cobra heads and cams. The supercharged Cobra switched to a cast-iron block for 2003, and a supercharged-application Aluminator gave 2003-2004 Cobra owners an aluminum-block alternative with a lower 8.5:1 compression ratio. A 9.8:1 compression short block then followed on for the three-valve 2005-2010 Mustang GT.
Factory Five Racing lent Ford one of its Challenge Car racers as the test mule for a 4.6 Aluminator, which the company rated at more than 650 bhp.
