GM LSA 6.2L Supercharged Engine with Tremec TR-6060 – Supercharged 6-Speed Manual Powertrain

The LSA 6.2L Supercharged V8 paired with the Tremec TR-6060 six-speed manual transmission is a proven high-performance GM powertrain designed to deliver massive torque, instant throttle response, and true driver engagement. Built for both street and track use, this combination blends factory-engineered durability with aggressive supercharged performance.

Engine Specifications – LSA 6.2L V8

• Displacement: 6.2 liters
• Block: Cast-iron (high-strength foundation)
• Induction: Eaton 1.9L TVS supercharger
• Configuration: OHV V8, supercharged
• Factory Output: ~556 HP
• Torque: ~551 lb-ft
• Fuel System: Electronic fuel injection

Performance Characteristics

• Instant boost and strong low-end torque
• Broad torque curve for aggressive yet controllable acceleration
• Consistent power delivery across the RPM range
• Engineered for reliability under high-load conditions

Transmission – Tremec TR-6060

• Type: 6-speed manual
• Design: Close-ratio gearing for improved acceleration
• Torque Capacity: Built to handle high-output V8 applications
