1996-Up GM Blazer/Jimmy Central Port (Vortech) Injection 4.3 V-6
The Vortech V-6 (60 degree) engine utilizes a single injector assembly which consists of a fuel meter body, fuel pressure regulator, fuel injector and six poppet nozzles with fuel tubs. The plenum (manifold) is a variable tuned design that splits the plenum in two during low and high RPM'S, which provides peak torque along with increased horse power. The transmission types available for this engine are 4L60, 4L60-E, and manual transmissions.
