A New Addition to the LS Family!
Introducing  the LS364/425! Starting with a lightweight but strong 6.0L aluminum cylinder block and durable rotating assembly, the LS364/425 features deep-breathing L92 aluminum cylinder heads and the high-lift LS3 camshaft. It’s a strong combination that provides exceptional horsepower and a broad torque band. It is also fuel injection-capable, using production-based components. Additionally, the LS364/425 is designed with the late-style 58X crankshaft and 4X camshaft sensors, enabling the use of the GM Performance LS3 controller kit.

We offer the LS364/425 as a long-block assembly, but our parts experts can help you with any additional parts you may need, including the induction system, ignition system or front-end accessory drive system. We can also provide upgraded camshaft choices for even more power!

THE HOT CAM ADDS HEAT TO THE LS364!
What happens when you take the LS364/425 6.0L and swap the LS3 camshaft for the racing-inspired LSHot Cam (P/N 88958753)? How about 475 horsepower and 453 lb.-ft. of torque. The key to the power boost is the Hot Cam’s 0.525-inch lift on both the intake and exhaust sides, along with 219-degree/228-degree duration specs. That’s less lift on the intake side than the LS3 cam, but considerably more duration, allowing the valves to stay open longer to draw in more air from the rectangular-port L92-style heads.

The crate engine package includes the intake manifold, throttle body and fuel rails, along with the ignition system and water pump. Use it with the LS376/480 controller kit P/N 19354330, which includes the throttle pedal for use with the engine’s electronically controlled throttle body.

OUR MOST POWERFUL NATURALLY ASPIRATED LS 6.0L!

Like our LS364/425, the LS364/505 starts with an aluminum 6.0L block topped with L92 heads. With Chevrolet Performance’s aggressive ASA camshaft—developed for the high-rpm world of circle-track racing—installed in the LS364 6.0L engine, it comes alive with 505 uncompromising horsepower.

That makes it the most powerful naturally aspirated 6.0L engine in our portfolio—and one that has an edge to it. You’ll notice it in the idle quality and you’ll feel it when the revs quickly climb. The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breathe exceptionally well at high rpm.

And for durability, we complement the cam with higher-rate valve springs. You’ll need tuning to make the most of the engine in a late-model GM vehicle. If you plan to use the engine in a vintage car, you’ll need LS376/525 Controller Kit P/N 19354332, which includes the throttle pedal to match its electronically controlled throttle body.

Direct from the Corvette, Camaro, and Chevy SS to your project vehicle!

The LS3 6.2L is the 430-hp standard engine in the Chevrolet Camaro SS and the all new RWD Chevy SS. It is a fantastic combination of high technology and uncompromising performance. Our LS3 crate engine comes complete, from the Chevy SS-specific oil pan to the ignition system. It also includes the EFI intake manifold assembly with injectors and throttle body, water pump, balancer, and 58X reluctor wheel. Inside, the LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.551-inch of lift on the 2.16-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves, enhancing the LS3’s tremendous airflow and broad torque curve. The Chevy SS oil pan doesn’t suit all installation applications. Use a vehicle-specific oil pan for original LS-powered vehicle or Chevrolet Performance’s Muscle Car Oil Pan Kit P/N 19212593 for older vehicles.

Our ‘Hot Cam’ Adds 65 HP To The Already-Potent LS3!

Our engineers never stop tinkering. When they took a production LS3 6.2L (376 cubic inches) engine and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958753), the result was a stunning 495 horsepower and 473 lb.-ft. of torque. That’s nearly 12 percent more power and torque from a simple camshaft change! We wasted no time in adding that terrific combination – dubbed LS376/480 – to our crate engine portfolio. The key to the power boost is the Hot Cam’s 0.525-inch lift on both the intake and exhaust sides, along with 219-degree/228-degree duration specs. That’s less lift on the intake side than the stock LS3 cam, but considerably more duration, allowing the valves to stay open a little longer to draw in more air from the rectangular-port L92-style heads. Use the LS376/480 with controller kit P/N 19258267, which includes a special pedal for use with the engine’s electronically controlled throttle body.

A BIGGER CAM FOR GREAT PERFORMANCE!

Chevrolet Performance's LS376/525 is one of our most powerful naturally aspirated 6.2L crate engines. It's based on the LS3, but adds our aggressive ASA camshaft to expand the performance range, particularly at high rpm, resulting in 525 horsepower and 486 lb.-ft torque.

The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breath exceptionally well at high rpm. And for the durability, we complement the cam with higher-rate valve springs. The LS376-525 long black is delivered without the intake manifold, coil packs, water pump, exhaust manifolds or other accessories.

Affordable LS3-Based High-Performance For The Street Or Track!

Using the LS3 engine as its foundation, the LS376/515 crate engine adds Chevrolet Performance’s racing-derived ASA Hot Cam and a carbureted intake system to produce 533 horsepower at a high-revving 6,600 rpm and 477 lb.-ft. of torque at 5,200 rpm. It’s a great engine for resto-mod classic and late-model muscle cars. The assembly includes a Chevy SS oil pan and LS3 cylinder heads, with high-flow, rectangular-port intake passages, as well as our unique, spider-type carburetor intake manifold. At the heart of the engine is the ASA cam, which extends the performance range of the LS3 with more duration. That means it holds the valves open longer, enabling greater airflow at higher rpm. Wind it out yourself and you’ll see what we mean!

Fuel-Injected Ferocity For Performance Cars Of All Ages

Forged Internals Support Higher Boost!

If you want to stretch the performance of a turbocharged or supercharged combination, Chevrolet Performance’s LSX376-B15 is the foundation you need! Its durable, all-forged rotating assembly supports up to 15 pounds of boost–and our ratings of 473 horsepower and 444 lb.-ft. of torque are only baseline numbers of what this engine can offer. The LSX376-B15 includes the six-bolt high-flow, rectangular-port LSX-LS3 heads. Additionally, we deliver the engine without an intake manifold and other accessories, allowing you to tailor the induction system and other features to suit the forced-induction setup of your choice.

A classic cubic-inch combination with the latest LS engine technology!

With the LSX Bowtie block, we’ve built a 21st century 454 with the latest technology. It’s lighter and more compact than an original Big-Block 454 – while delivering Big-Block output of 627 hp and 586 lb.-ft. – but requires no more space under the hood than a production LS engine.

The LSX454 is filled with an all-forged, super-tough rotating assembly and features a pair of our deep-breathing LSX six-bolt cylinder heads. It also comes dressed with great-looking, orange powder-coated valve covers with engraved “LSX454” logos.

Chevrolet Performance delivers the engine without an intake manifold and other accessories. Use LSX-LS7 single plane carbureted intake manifold P/N 19244033. The LSX454 valve covers do not include provisions for mounting ignition coil brackets. Aftermarket or custom relocation brackets must be obtained. It also includes an 8-bolt crankshaft flange that may require an adapter for use with some transmissions.

This LS3-based Racing Engine Is A Lightweight Powerhouse!

Chevrolet Performance’s deep-breathing, high-revving CT525 6.2L crate engine is based on the LS engine family and delivers serious power for serious racing series, including Super Late Model and modifieds.

It is similar to the 6.2L LS3, but we’ve adapted it to circle track racing with a carbureted intake manifold, 6-quart racing oil pan and more. The engine is lightweight and strong, using an aluminum block with cross-bolted 6-bolt main caps and high-flow LS3 rectangular-port cylinder heads. This combination produces 533 hp at 6,600 rpm and a hefty 477 lb.-ft. of torque at 5,200 rpm.

The CT525 6.2L comes with coil-on-plug ignition, and an SFI-certified balancer. All that’s needed to complete the assembly is a carburetor, starter and our LSX ignition controller P/N 19355863 – all available from Davis GMC Buick, Medicine Hat.
