EFI 58x™ BBC

EFI Connection's 58x BBC systems are designed to output the 58x crank signal of a GM Gen IV LS-Series engine. This means that 58x compatible ECUs can now be used on 58x equipped BBC engines! Available with 1x and 4x cam signal solutions.

The differences in the variety of available BBC engines required us to design and manufacture many different 58x BBC conversion kits. Get started by using the conversion matrix below to choose the appropriate 58x BBC conversion for your engine.
