The pace of LS1 technology has evolved quickly since the engines introduction in
For 2002, new Corvettes use a 10.5:1 LS6 engine that makes 405 net horsepower on todays pump gas. And thats real power as installed in the vehicle, not phony musclecar horsepower. It does this while meeting all of todays stringent emissions and fuel economy standards. The Vettes 345ci engine is not your fathers LS6 big-block, but its not a conventional small-block, either. The LS6 is the newest member of Chevys Gen III small-block family, a ground-breaking, high-tech pushrod engine thatexcept for the connecting rod bearingsshares no parts with any classic Chevy small-block.
Gen III small-blocks debuted as the LS1 in 97 Vettes. As of 2002, only fullsize vans retain conventional small-blocks, but even that era is coming to an end. The high-tech mill is rapidly gaining favor in numerous racing venues where fuel-injected engines are allowed to compete. Takeouts are appearing in salvage yards, and GM as well as aftermarket performance parts are beginning to fill up the pipeline. With help from leading Gen III pioneers including General Motors Performance Parts (GMPP), Hank the Crank (HTC), The School of Automotive Machinists (SAM), TTS, Westech Automotive, and other sources lets take a look at what makes this engine run.
