ATK High Performance Engines
<h3>About ATK High Performance Engines</h3><p>Few names carry as much weight in the performance engine world as <strong>ATK High Performance Engines</strong>. <a href="/3092-atk-high-performance-engines">ATK</a> traces its roots back to 1936, when its parent organization began remanufacturing engines from war-surplus vehicles in Holland. Decades of refinement followed, and in 2007 ATK launched its dedicated High Performance Division in Grand Prairie, Texas — a move that transformed the brand into a go-to source for serious engine builders across the country.</p><p>What sets ATK apart is a philosophy of reverse engineering. Rather than simply replicating OEM designs, ATK engineers identify known weaknesses in factory engine architecture and address them with upgraded components before a single engine leaves the shop. The result is an engine that often exceeds original factory durability and performance standards. Every ATK high-performance engine is backed by a <strong>24-month, unlimited-mile warranty</strong> — a standard that was groundbreaking when ATK first introduced it and remains a benchmark in the industry today.</p><h3>Engine Lineup: Something for Every Build</h3><p>ATK's catalog is built around flexibility. Whether you're dropping a freshly built motor into a classic muscle car, tackling a modern swap project, or building a dedicated track weapon, ATK offers a configuration to match. Their <a href="/3092-atk-high-performance-engines-engine-complete-assembly-15341">complete engine assemblies</a> span GM, Ford, and Chrysler platforms, with options ranging from stock-displacement rebuilds to stroker combinations pushing well past 600 horsepower.</p><p>The lineup is organized into two flagship series. The <strong>Signature Series</strong> targets street rods, restomods, and daily drivers that need reliable power without fuss. The <strong>Elite Series</strong> steps up the specification for racers and builders who demand premium components throughout. Within each series, buyers can choose between short block, mid-dress, and fully dressed complete engine configurations — making it straightforward to match the engine to the specific needs of any build.</p><p>GM enthusiasts will find an extensive selection covering small-block Chevy (SBC), big-block Chevy (BBC), and modern LS and Gen V LT platforms. Ford builders can choose from 302, 347 Stroker, and 351 Windsor combinations. Mopar fans are not left out either, with 360 Magnum and other Chrysler options rounding out the catalog.</p><h3>Beyond Complete Engines</h3><p>ATK's expertise doesn't stop at turnkey assemblies. The brand also offers a robust selection of <a href="/3092-atk-high-performance-engines-cylinder-heads-201280">cylinder heads</a> engineered to the same exacting standards as their complete engines. Cast from A356 aluminum alloy with optimized port designs, stainless steel valves, and manganese bronze valve guides, these heads are built to complement ATK engine packages or upgrade an existing short block. Coverage spans SBC, BBC, LS, LS3, and small-block Ford applications.</p><p>Builders looking to dress their completed rotating assembly will also find <a href="/3092-atk-high-performance-engines-engine-valve-cover-5772">engine valve covers</a> and <a href="/3092-atk-high-performance-engines-engine-cylinder-head-5304">individual cylinder head</a> components available — useful when completing a custom build or replacing worn top-end hardware. ATK also offers select drivetrain support components, including <a href="/3092-atk-high-performance-engines-power-steering-pump-7380">power steering pumps</a>, reflecting the brand's commitment to serving as a comprehensive powertrain resource rather than a single-product supplier.</p><h3>Why Builders Trust ATK</h3><ul><li>Industry-leading 24-month, unlimited-mile warranty on performance engines</li><li>Reverse-engineered designs that address known OEM weak points</li><li>Multiple build levels — short block, mid-dress, and complete — for budget and application flexibility</li><li>Broad platform coverage: GM, Ford, Chrysler, and more</li><li>Aluminum cylinder heads cast from A356 alloy with fully assembled valvetrain components</li><li>Elite and Signature Series options for both street and race applications</li></ul>
