EFI 4x™ SBC
An EFI 4x SBC conversion will equip your Small-Block Chevy engine with the crank and cam signal components necessary to be controlled by 1996-newer GM ECUs that support a single coil and distributor ignition system.
EFI 4x™ LT1/LT4
Double roller timing sets create clearance issues within the timing cover of 1992-1997 LT1 engines and the 1996-1997 GM 4x crank reluctor is not shaped to allow for the double roller chain. EFI 4x LT1/LT4 conversions resolve all clearance issues and provide the 4x crank signal for the 1996-1997 LT1/LT4 PCM.
EFI 4x™ BBC
An EFI 4x BBC conversion will equip your Big-Block Chevy engine with the crank and cam signal components necessary to be controlled by 1996-newer GM ECUs that support a single coil and distributor ignition system.
