Jenvey Chevrolet LS3 - Heritage V8 ITB Kit

The Jenvey Chevrolet LS3 - Heritage V8 ITB Kit (CKCT07) fuel-injects the LS3 V8 through four Heritage IDA-style throttle bodies with cross-bank linkage, combining classic downdraft looks with modern EFI for road, track or rally.

Designed and manufactured by Jenvey Dynamics in the UK, Jenvey's individual throttle body systems are prized for crisp throttle response, strong torque and the unmistakable induction sound. An aftermarket ECU is required.

Key Features:

• Built & Balanced: Supplied assembled and balanced by Jenvey, ready to fit.
• Improved Fuel Mixing: Injectors sit further upstream, in the part-throttle turbulence of the butterfly, for better atomisation, torque and power.
• Maximum Flow: Profiled spindles minimise cross-sectional area at full throttle.
• Fine Low-Speed Control: A shallow 8° shut angle gives finer control at small throttle openings.
• Proven Durability: Major components are rig tested to over 1 million cycles.
• UK Made: Cast in Jenvey's own foundry and machined in the same UK factory; castings are lighter than fully CNC-machined parts.
• Modular System: Bespoke throttle sizes and system lengths can be built to order.
