ATK High Performance Engines

<h3>ATK High Performance Engines: American Muscle, Built Right</h3><p><strong>ATK High Performance Engines</strong> has grown into one of the largest performance engine shops in the United States, earning a reputation for quality, craftsmanship, and broad platform coverage. <a href="/3092-atk-high-performance-engines">Founded in 2007 and headquartered in Grand Prairie, Texas</a>, ATK was built on a straightforward mission: produce top-quality engines using name-brand components, at a range of power levels to fit every budget and application.</p><p>Leading the company is a team of dedicated engine builders whose combined experience spans street, strip, marine, and off-road applications. With over 40 years of race engine development knowledge guiding the product line, ATK brings professional-grade expertise directly to enthusiasts and builders. Every engine that leaves their facility is dyno-proven, ensuring the horsepower ratings on paper translate to real-world results under the hood.</p><h3>A Lineup Built for Every Builder</h3><p>ATK organizes its performance engine catalog into two flagship tiers. The <strong>Signature Series</strong> is engineered for street rods, restomods, and daily drivers that demand reliable power without unnecessary complication. The <strong>Elite Series</strong> raises the bar further, targeting hardcore racers and serious builders who insist on premium components throughout the assembly. Within both series, buyers can select from short block, mid-dress, or fully <a href="/3092-atk-high-performance-engines-engine-complete-assembly-15341">complete engine assembly</a> configurations, making it easy to match the engine package to any build's specific requirements and budget.</p><p>Platform coverage is one of ATK's defining strengths. <a href="/3092-atk-high-performance-engines-engine-complete-assembly-15341">GM enthusiasts</a> are well served with small-block Chevy (SBC), big-block Chevy (BBC), modern LS, and Gen V LT offerings. Ford builders can choose from 302, 347 Stroker, and 351 Windsor combinations, while Mopar fans will find 360 Magnum and other Chrysler-based options rounding out the catalog.</p><h3>Short Blocks, Cylinder Heads & Parts</h3><p>Not every builder needs a fully dressed engine, and ATK accommodates that with a robust selection of <a href="/3092-atk-high-performance-engines-engine-short-block-5244">engine short blocks</a> — the perfect foundation for a custom build using your own top-end components. For those working from the heads down, ATK's <a href="/3092-atk-high-performance-engines-engine-cylinder-head-5304">engine cylinder heads</a> are cast from A356 aluminum alloy and feature optimized port designs, stainless steel valves, and manganese bronze valve guides. Cast, machined, and assembled in the USA, these heads accept factory components without modification and are available for SBC, BBC, LS, LS3, and small-block Ford applications.</p><p>Beyond rotating assemblies and top-end components, ATK also carries a growing catalog of <a href="/200373-engine-parts-accessories-atk-high-performance-engines-3092">engine parts and accessories</a> — valve covers, individual cylinder head components, and other hardware useful for completing or refreshing a build. This positions ATK as a comprehensive powertrain resource rather than just a crate engine supplier.</p><h3>Backed by an Industry-Leading Warranty</h3><p>ATK stands behind every engine they build with a 24-month, unlimited-mile warranty on their performance engines — a statement of confidence that is rare in the high-performance segment. Whether you are swapping in a crate engine for a weekend cruiser or building a purpose-built race car, ATK High Performance Engines delivers the combination of quality, selection, and peace of mind that serious builders rely on.</p>

Very easy

Easy Hassle free

Best price for a product I've been shopping for, for months, and when I saw Autoplicity having it for A LOT cheaper, putting the product in my sweet spot price wise, I didn't hesitate to order. <br><br>My bank was a little slow to post the transaction, and I was suprised to get a human on the phone with no effort to make sure my order was properly processed. The gentleman I spoke with was very friendly and promptly answered all my questions. <br><br>Only the $5 I'm getting back for this review can make this deal any better, as I have no suggestion for improving the transaction I made with them.

Best price for the optima battery I needed for my boat, I will definitely add this site to my favorites.

Pricing was good and customer service quick to respond.
