Ford Performance has taken the technology and hardware developed for the Shelby GT350 Mustang and has created the ultimate Naturally Aspirated, 5.2L cross-plane crankshaft crate engine. With a rating of 580 horsepower, the new Aluminator 5.2 XS is the most powerful naturally aspirated modular crate engine ever built by Ford Performance. This is the worthy successor of our previous rendition-the "A50XS". Every Aluminator is hand assembled by the same technicians that build the Mustang Cobra Jet drag racing engines. Premium aftermarket components are used to ensure durability like unique Manley connecting rods with ARP rod bolts and Mahle forged pistons. Unique components developed specifically for the Cobra Jet racing program are used including Cobra Jet short runner-high RPM intake manifold, 1517 CFM dual 65mm CJ Throttle Body, and Competition High RPM pulse ring. Ford Performance Engineers developed a balanced combination of high end, 580 horsepower and strong mid-range torque with the Cobra Jet intake manifold, unique camshafts and fully CNC ported GT350 cylinder heads.
