The fuel-injected Chevrolet 4.3 Vortec V6 offers plenty of reliable horsepower in the Sidekick/Tracker. It fits fine with Suzuki Lightning Conversions' kit. The complete kit includes a crated 4.3 Vortec fuel-injected V6 with computer, 700R4 automatic transmission, engine and transmission mounts, all brackets and engine-mounted parts (front dress, etc.), radiator, and Tom Wood driveshafts. The company also offers the kit without the engine and tranny for those who already have them.
