GM's New 6.7-Liter LS6 V8 Uses Aluminum Block and Dual Injection

The LS6 isn't just a Corvette engine — it's GM's argument that a pushrod V8 still has a future in an era of tightening emissions rules. The engineering choices here, aluminum block and dual injection, are about regulatory survival as much as performance. What this really signals is whether GM believes it can keep naturally aspirated, large-displacement V8s viable in full-size trucks and performance cars long enough to matter. That's a harder question than any horsepower figure answers.
