The Most Powerful V8 EVER

There are two numbers that make the Z60 such an incredible feat of engineering, so we'll cut to the chase: 670 and 8,400.

Want to guess what those numbers mean?

If your first thought was "horsepower" and "RPM", then congratulations! You're correct! 

That's right, this is a car that produces an incredible 670 horsepower at 8,400 RPM. 

At the heart of Chevy's hottest new announcement is the LT6 V8 engine, which has the distinction of being the single most powerful naturally aspirated V8 engine to grace a production car. Ever. The same kind of horsepower that was the domain of formula-one racecars and custom hot rods will be pulling into Chevrolet dealerships before you know it.
