Katech Engineering LLC - Custom Spec LT Performance Engines

Custom Spec LT Performance Engines Engineered for Street, Track, and Competition

Katech LT engines are custom spec high-performance engines engineered around GM Generation V LT architecture, including LT1, LT4, and other Gen V platforms. These LT engine combinations are specified, engineered, and assembled using race-proven components, precision machining, optimized compression strategies, and advanced valvetrain systems designed for high power output and sustained durability in demanding environments such as street performance, drag racing, and professional competition.

Each LT engine package is developed as a complete performance system tailored to your specific goals. Critical specification decisions, including displacement strategy, airflow and head flow optimization, camshaft profiles, valvetrain geometry, fuel system calibration, and thermal management, are determined during the engineering process to achieve efficient combustion, robust oil control, and structural integrity under high load conditions. This systems-based approach ensures repeatable performance and reliability across both street and competition use cases.

For customers searching for LT crate engines or performance crate engines, Katech delivers fully assembled custom spec LT engine packages configured for direct installation and application-matched performance. These are not mass-produced crate engines. Each LT engine reflects a race-informed specification and assembly standard that supports dependable, repeatable results tuned to your intended platform and performance strategy.
