The Katech Installation Process
Vehicle Inspection
Before performance modifications begin, the vehicle's condition and existing engine operation can be evaluated to identify concerns that may affect the completed performance combination.
Baseline Dyno Testing
Baseline chassis dyno testing is included to document vehicle performance before modifications and establish a reference point for the completed package.
Cylinder Head Preparation
The factory LT1 cylinder heads receive Katech CNC porting and basic cylinder head assembly service. CNC porting is designed to improve airflow through the cylinder head intake and exhaust ports, supporting the increased airflow demands of the Torquer LT1 camshaft and 565HP performance combination.
Camshaft and Valvetrain Installation
The Katech Torquer LT1 camshaft is paired with the 660-Lift Platinum Gen V LT valve spring kit, GM LS7 lifters, GM lifter trays, and Trend pushrods. VVT lockout components and AFM delete rivets are included to support the camshaft conversion.
Supporting Engine Components
Supporting engine components include GM LT1 head gaskets, ARP head bolts, a 160-degree thermostat, Katech billet thermostat housing, Brisk Racing spark plugs, required engine seals, hardware, and service fluids.
ECU Calibration
The package includes HP Tuners credits and ECU calibration services appropriate for the K-Spec 565HP heads and cam performance combination. Calibration is tailored to support the modified camshaft, cylinder head airflow, and overall engine operation.
Dyno Calibration and Validation
Chassis dyno work is included to evaluate the completed performance combination and support calibration adjustments. Dyno testing provides an opportunity to assess engine response and performance following the modifications.
Street Calibration
Street calibration is included to refine throttle response, part-throttle operation, idle quality, and general drivability with the upgraded camshaft and cylinder heads.
The Katech Difference
Katech Engineering has been developing, machining, assembling, and validating high-performance engines and components since 1977. From professional motorsports programs to premium street performance packages, Katech focuses on complete engineered systems rather than random combinations of parts.
The K-Spec 565HP Heads and Cam Package takes advantage of Katech's engine development, CNC machining, cylinder head preparation, and calibration expertise to deliver a cohesive naturally aspirated LT1 performance combination.
Katech's experience with the GM LT engine platform helps bring together cylinder head airflow improvements, camshaft selection, valvetrain components, and engine calibration in a coordinated performance package.
