Our EFI 24x™ conversion for 1996-newer Vortec small-block Chevy engines allows for a Gen III LS-Series PCM with coil per cylinder ignition. REQUIRES THE USE OF A SINGLE ROW TIMING SET. This kit includes a plastic Vortec timing cover, 24 tooth crankshaft reluctor, crankshaft position sensor, and aluminum 1x cam sync distributor. The Vortec timing cover included in this kit will leak on 1995-older small-block Chevy engines. SBC balancers wider than 1.325" will not clear timing cover and CKP sensor.
