GM LT4 6.2L Supercharged V8 + Automatic Transmission

The GM LT4 6.2L Supercharged V8 + Automatic Transmission is a high-performance powertrain package designed for enthusiasts, professional builders and automotive projects requiring serious V8 performance with automatic transmission convenience.

Available from Prime Motor Ltd, this package combines the legendary GM LT4 6.2L Gen-V V8 with a compatible automatic transmission configuration, providing an excellent foundation for high-performance street cars, muscle cars, restomods, engine swaps and custom performance builds.

LT4 6.2L Supercharged V8

The GM LT4 is a 6.2-liter / 376-cubic-inch Gen-V small-block V8 featuring factory supercharging and direct fuel injection.

In Chevrolet Performance’s crate-engine specification, the LT4 is rated at up to:

• 650 horsepower
• 650 lb-ft of torque
• 6.2L displacement
• 10.0:1 compression ratio
• 6,600 RPM maximum recommended engine speed

The combination of supercharging and 6.2L displacement gives the LT4 strong torque delivery and exceptional performance potential.

Supercharged Performance

The LT4 uses an Eaton TVS R1740 supercharger to force additional air into the engine.

This allows the engine to produce significantly greater power and torque than a naturally aspirated 6.2L V8.

The result is a responsive, high-output powerplant suited to demanding performance applications.

Automatic Transmission

Pairing the LT4 with an automatic transmission creates a complete high-performance powertrain solution.

An automatic transmission can provide:

• Smooth gear changes
• Strong acceleration
• Convenient everyday operation
• Consistent power delivery
• Easy integration into many performance applications
• Excellent suitability for street and performance builds

Important: The exact automatic transmission supplied or compatible with an individual LT4 package depends on the specific engine, vehicle application and configuration. Customers should confirm the exact transmission model, controller, torque converter, bellhousing configuration and included components before purchase.
