What Are the 60 and 62 LS Engines?
Let's break down what these two engine types actually are. Both belong to Chevrolet’s legendary LS engine family, known for their versatility, durability, and high performance. But specific differences in design, displacement, and application make each unique. Here’s a straightforward look:
Definition of the 60 LS Engine Series
- Displacement: Typically 6.2 liters (376 cubic inches)
- Production Years: Mainly used in trucks and performance cars from the early 2010s onward
- Common Models: LS3, L92, and L99
- Purpose: Emphasized on high torque and power, suitable for street and track use
Definition of the 62 LS Engine Series
- Displacement: Usually 6.0 liters (364 cubic inches)
- Production Years: Early 2000s to early 2010s
- Common Models: LS2, LQ4, and similar variants
- Purpose: Focused on a good balance of power and efficiency, often used in SUVs and trucks
Now, let's dive into the key distinctions that differentiate these engines at a glance:
| Feature | LS62 Series | LS60 Series |
|---|---|---|
| Displacement | 6.0 L | 6.2 L |
| Cooling System | Water-cooled | Water-cooled |
| Compression Ratio | Varies (8.5:1 to 10.7:1) | Similar, often higher in performance models |
| Power Output | 300-400 HP | 426-525 HP (depending on the model) |
| Typical Use | Trucks, SUVs, base performance builds | High-performance cars, racing, muscle cars |
| Common Models | LS2, LQ4 | LS3, L99, L92 |
Why Do These Differences Matter?
Knowing whether you’re dealing with a 60 or 62 LS engine isn’t just about numbers. It impacts compatibility, performance potential, cost, and upgrade paths. For example, a 6.2L LS3 engine offers more horsepower right out of the box than a 6.0L LS2, but it may also be more expensive and require different parts for installation or upgrades.
Why It Matters for You:
- Performance: The 6.2L engines tend to produce more power and torque, making them ideal for high-performance builds.
- Cost: Typically, 6.0L engines are cheaper and more plentiful on the used market.
- Compatibility: Frame mounts, accessories, and ECU tuning may vary between these series.
- Upgrade Potential: 6.2L engines often respond well to modifications like forced induction, making them favorites for custom projects.

Let’s explore deeper into their specifications, applications, and how to choose the right one for your needs.
Displacement and Power
| Model | Displacement | Power Range (HP) | Torque Range (lb-ft) |
|---|---|---|---|
| LS2 (62 series) | 6.0 L | 390-400 | 400-410 |
| LS3 (60 series) | 6.2 L | 426-430 | 424-428 |
| L92 (62 series) | 6.2 L | /reg. 395-403 | 410-424 |
| L99 (60 series) | 6.2 L | 400-426 (with VVT) | 415-430 |
Note: Variations depend on specific models, year, and modifications.
Internal Components and Performance
- Cylinder heads: The 60 series engines often feature higher-flow aluminum heads suited for performance applications.
- Cam profiles: 60 series models often come with cam profiles designed for higher horsepower, especially in performance variants.
- Intake manifolds: Different for each series, can be upgraded based on your power goals.
- Valvetrain: Variations in performance and durability, especially with aftermarket options.
Application and Suitability
| Use Case | LS62 Series | LS60 Series |
|---|---|---|
| Daily driving | Yes | Yes |
| Performance upgrades | Yes | Yes, especially for high HP tuning |
| Racing and track | Less common | Popular for racing builds |
| Budget-friendly projects | More common | Slightly pricier but more available |
Tips for Choosing the Right Engine
- Assess Your Goals: Want a daily driver? Focus on reliability. Building a race car? Opt for a higher-performance variant.
- Budget Considerations: LS2 and LQ4 are more affordable and widely available.
- Compatibility: Check mounts, ECU, and transmission compatibility.
- Upgrade Potential: Consider the availability of aftermarket parts for your chosen engine.
Common Mistakes and How to Avoid Them
- Ignoring Compatibility: Not all LS engines fit all models; verify mounting points, oil pan clearance, and accessory fitment.
- Overlooking Modifications: Upgrading heads, cam, and intake can maximize each engine's potential without additional costs.
- Choosing Based Solely on Displacement: Focus on the entire package — power output, intended use, and budget.
Variations Similar to the 60 and 62 LS Engines
- LS1: Older 5.7L engine that started the LS series evolution.
- LS7: High-performance 7.0L engine used in Corvettes.
