EFI 4x™ SBC
Whether you are updating your early SBC electronic fuel injection system to use a newer ECU or adding electronic fuel injection to your SBC engine for the first time, an EFI 4x SBC conversion will equip your SBC engine with the crank and cam signal components necessary to be controlled by 1996-newer GM ECUs.
EFI Connection's 4x SBC systems are designed to output the 4x crank and 1x cam signal of a GM Vortec V8 engine. This means that the popular GM# 12200411 PCM can be used with single coil and distributor ignition for 4x equipped SBC engines!
The differences in the variety of available SBC engines required us to design and manufacture many different 4x SBC conversion kits. Get started by using the conversion matrix below to choose the appropriate 4x SBC conversion for your engine.
