|---|---|---|
| Displacement: | 6.0L (364 ci) | 5.7L (346 ci) |
| Horsepower: | Varies by model (400-415 hp) | Varies by model (305-405 hp) |
| Torque: | Varies by model (400-450 lb-ft) | Varies by model (400-420 lb-ft) |
| Power Delivery: | More aggressive power curve with higher peak output | Linear and smooth power curve |
| Intake Manifold: | True dual-plane design for improved low-end and mid-range torque | Mostly single-plane design for higher top-end power |
| Exhaust Manifolds: | Stainless steel headers for improved flow | Cast iron manifolds on early models, stainless steel on later models |
| Crankcase: | Aluminum | Aluminum |
| Connecting Rods: | Forged | Forged |
| Applications: | Camaro, Corvette, GTO, Pontiac G8, Trailblazer SS | Camaro, Corvette, Firebird, GTO, Pontiac Trans Am |
| Fuel: | Requires premium fuel | Usually works on regular or premium fuel |
| Availability: | Less common in newer cars due to discontinuation | Widely available in various platforms |
| Cost: | Typically more expensive due to lower production numbers and performance | Generally more affordable due to wider availability |
Additional Considerations:
- Both engines respond well to modifications, unleashing even more power with upgrades.
- The LS2’s increased displacement contributes to its higher torque and slightly higher fuel consumption.
- Parts availability remains good for both engines, though rarer parts might be harder to find for the LS2.
