These classic gold engine-toppers with transmission control are complete throttle body kits, suitable for everything from your junkyard 5.3 to a Stroker 427—and they deliver old-school carburetor looks with EFI technology and reliability. Whether a do-it-yourself hot rodder or professional EFI tuner, the features of the FiTech Retro LS EFI 600 hp system are sure to inspire you.

* Windshield-mount for control
* Flow-matched 80 lb. injectors
* Self-learning ECU with touchscreen controller for easy setup and configuration
* Semi-sequential fuel and full spark control
* Bosch wideband controlled (self-learning)
* 24X and 58X crank and cam compatible
* 1 BAR MAP sensor—TPS-IAC sensor
* Speedometer Output Driver for most speedometers

* Knock sensor control
* Available transmission control feature is suitable for 4L60, 4L65, or 4L80 GM transmissions
