6.0 LS Engine Build With Parts From Summit Racing

By now I’m sure you’ve heard of the Chevrolet LS engine. If not, I’m glad you’ve finally found a way to get out from under that rock. The LS-based engine platform has definitely taken over as the go-to engine swap in the last 5-10 years, and its popularity is still on the rise. Different variations of the engine can be found in everything from a bare-bones work truck all the way up to a factory-supercharged Corvette. Due to the different vehicle applications in which GM put these engines from the factory, obtaining an 6.0 LS engine for your swap is easy. Just skim your local classifieds, or make a trip to the salvage yard, and you’ll probably have a dozen or so to choose from on any given day. But what if you’re skeptical about buying a used engine?

Purchasing a used, or “pull out” engine, does come with some risks, and you should definitely consider them before purchasing. Since most of the odometers in newer vehicles are digital, you can’t simply glance into a vehicle to see how many miles are on it. Even if the seller knows the mileage, you still just have to trust his word. Compression tests can be done, and salvage yards will usually give you some kind of guarantee, but what if you want more piece of mind? Good news, there are options for brand-new LS-based engines.

When the opportunity to build a new LS engine presented itself to us, we knew right where to look for all of the parts we’d need. Summit Racing was our first and only phone call. Summit has been around since 1968 and is continuing to grow every year. In fact, it just completed the construction of its fourth distribution site located in Arlington, Texas. It also carries products from more than 1,500 manufacturers, so we were positive the company would be able to get us everything we needed to complete our engine build.

We discussed our options with a Summit rep and came up with a plan to build a strong and reliable engine that would also make great horsepower. Also, we decided to go with a short-block from BluePrint Engines. We also opted for a complete top-end engine kit from Trick Flow to complete most of the build. However, there are a lot of smaller parts we still needed to complete the engine assembly and get it ready to drop into our project. Follow along and we’ll tell you all about it.

These goals reflect a dedication to achieving high power and performance levels, pushing the vehicle’s capabilities to new heights.

 

What issues did the NA C6z Build face, and what changes were planned to address them?

Issues with the NA C6z Build

The primary problem with the NA C6z Build was noticeable valvetrain noise, especially at cold starts, due to some lifter knock. This was traced back to the use of springs with excessive seat pressure for the installed lifters, which couldn’t hold the pressure. Specifically, the springs were calibrated for an open pressure of about 540lb, far exceeding the lifters’ capability of 420lb, leading to their overnight collapse and a subsequent ‘bouncing’ until they stabilized on startup.

Additionally, the engine’s performance on the dyno revealed inconsistencies. The power output peaked at 6100rpm, lower than the expected 65-6700rpm with the current camshaft. Attempts to further push the engine beyond 7000rpm resulted in a loss of power, a clear sign of valve float caused by collapsing lifters at high revolutions. This issue was particularly apparent during shifts at full throttle.

Planned Changes to Address Issues

To tackle these challenges, a comprehensive overhaul of several engine components was planned:

• Exhaust System: Upgrade to 2″ to 2-1/8″ stepped headers with 3.5″ collectors to improve exhaust flow.
• Intake System: Install a high-performance intake base with a custom fabricated lid and a 4.5″ air intake featuring a premium filter.
• Camshaft: Swap in a custom camshaft with greater duration, increased lift, and a wider LSA, though specific details remain confidential.
• Cylinder Heads: Send the heads for further milling to increase compression.
• Lifters and Pump: Replace with new Johnson lifters and a high-capacity oil pump to ensure adequate lubrication and support for modifications.
• Throttle and Water Systems: Upgrade to a 108mm throttle body and install an electric water pump for more efficient cooling and air intake management.
• Supplementary Kits: Add a methanol injection kit for better performance and a vacuum pump for improved pressure regulation.
• Exhaust: Fit a high-performance exhaust setup for enhanced sound and efficiency.

With these modifications, the goal is to achieve a power output of around 700 horsepower at the wheels, with torque estimated between 550-560 lb-ft. The decision was made to avoid moving to a solid roller setup for the time being, although there is a potential plan to develop a second motor with even more advanced components.

What issues were encountered during the NA C6z build’s performance event?

Issues Faced During the NA C6Z Build’s Performance Event

On the first run, several unexpected challenges arose. The beginning of the runway was extremely dusty, leading to traction issues. This lack of traction made it difficult to accelerate efficiently. Initially, the driver attempted a moderate start, swiftly transitioning into second gear to maintain control. While the car managed to hook well initially in second gear, the power surge that followed compromised stability.

As the car approached the top end of the run, it lost momentum unexpectedly a few feet before the finish line. An attempt to shift into fifth gear to regain power was unsuccessful; the vehicle suddenly lost power and couldn’t continue. As the car decelerated, it shut off completely and refused to restart.

Upon inspection, a fuel pressure issue was identified. It was discovered that a fuel leak was causing the problem. The tow truck driver noticed that the fuel rail had come loose, leading to an injector popping out and spilling fuel. Fortunately, a protective mechanism was in place that likely prevented engine damage, safeguarding the motor from a potential disaster.

 

What performance outcomes were achieved with the NA C6z at a half-mile event?

Performance Outcomes Achieved with the NA C6z at a Half-Mile Event

The half-mile event showcased impressive results for the NA C6z, despite challenging conditions. The car secured a first-place finish in the naturally aspirated category, demonstrating its superior performance capabilities.

Key Metrics of Success:

• Top Speed: The car achieved a remarkable top speed of 178 mph.
• Consistent Performance: Across three runs, the vehicle consistently reached speeds above 170 mph, clocking in at 172 mph, 174 mph, and 178 mph.

Despite facing a significant headwind of approximately 20 mph and dealing with a density altitude exceeding 2000 feet, the NA C6z maintained its high-speed prowess, culminating in a victory that highlighted its engineering and driving excellence.

 

What are some of the challenges and adjustments made during the NA C6z build?

Challenges and Adjustments During the NA C6z Build

Building the NA C6z brought its fair share of hurdles and necessary tweaks. One immediate concern was the excessive noise from the valvetrain upon startup. Particularly during cold starts, there was a noticeable lifter knock. This issue stemmed from the PAC springs installed, which exerted considerable seat pressure, far more than the lifters could handle. To put it into perspective, the Johnson lifters are rated for a maximum of 420lb open pressure, but the springs were set for about 540lb open. Consequently, this misalignment caused the lifters to compress overnight, leading to a brief but unsettling ‘bounce’ until they stabilized.

Another significant challenge was observed through the dyno performance. The expected power peak with the chosen camshaft should have been within the 6500 to 6700 RPM range. Instead, it maxed out at just 6100 RPM. Although the rev limit was positioned at 7700 RPM, any attempts to push beyond 7000 RPM resulted in a noticeable decline in performance. This was due to the lifters collapsing at higher RPMs, triggering valve float—a condition known for hampering smooth power delivery. The effects of this were particularly evident during shifts, where momentary hesitation was felt before power resumed. This issue typically emerged under full throttle or during shifts at elevated RPMs.

In summary, the build required significant attention to ensure compatibility between components like the springs and lifters, as well as adjustments to optimize engine performance across the RPM range.

 

What changes are being implemented in the revised NA C6z build?

What’s New in the Revised NA C6z Build?
