Comments (0) Industry News

Chevy's Small Block V8 has been around for decades. We can safely say that it has stood the test of time. And during that time, it has continually been made better and better.

And at the SEMA Show in November, Chevrolet will unveil its new ZZ6 5.7L crate engine as the newest upgrade to the legacy.

The engine boasts of 405 horsepower and 405 lbs-ft of torque. And that's that huge power potential for any project car!

But what actual improvements have Chevy made to their Small Block?

The new ZZ6 features Fast Burn aluminum cylinder heads and an updated valvetrain to deliver enhanced high-RPM performance. Bigger intake runners increase airflow, while the tapered valve springs allow for less reciprocating mass. Forged steel crankshafts and high-silicon aluminum pistons are placed inside a cast iron block, making this engine top of the line.

The ZZ6 is available in two versions. The first version is of a base configuration which comes with an intake, distributor, and water pump, but does not include a carburetor and other accessories. The second Turn Key version comes with a carburetor, air cleaner, started, alternator, and every other required component.

We'll all have to wait for the official announcements at this year's SEMA Show.
