Retro LS Port 750 HP EFI System w/LS3 Intake

The Retro LS Port 750 HP EFI System with LS3 Intake is purpose-built for LS engine builders seeking modern fuel injection performance wrapped in a classic, carbureted aesthetic. This system bridges the gap between vintage street rod styling and contemporary engine management, making it ideal for restomod projects, classic muscle cars, and traditional hot rods where authentic appearance matters as much as reliability. The 750-horsepower capability provides ample headroom for naturally aspirated LS builds while maintaining the iconic retro fuel bowl look that defines the golden era of American performance.

Built on FiTECH's proven electronic fuel injection platform, this system combines a traditional carb-style body housing with fully sequential multiport injection and self-tuning capability through onboard sensors and adaptive algorithms. The included LS3 intake manifold is engineered for optimal air velocity and fuel atomization across the RPM range, delivering consistent cold starts, smooth idle characteristics, and response identical to modern EFI systems despite the nostalgic exterior design. The 36.85-pound assembly integrates fuel delivery, ignition timing control, and emissions management into a single compact package that bolts directly to LS-platform cylinder heads, requiring minimal fabrication or traditional fuel system modifications.

Builders restoring first-generation Camaros, Chevelles, or third-gen Corvettes benefit most from this solution, as it preserves engine bay authenticity while eliminating carburetor tuning headaches and fuel system complexity. The retro LS Port 750 HP EFI System works seamlessly with stock LS cores up through modern LS3 and LS7 variants, adapting to different displacement, aspiration, and fuel octane requirements automatically through its integrated computer. Installation fits standard hood clearances and works with most traditional radiator configurations, making it an intelligent choice for builders prioritizing visual correctness without sacrificing drivability, fuel economy, or cold-weather starting reliability.
