Hennessey’s Z/28 Performance Upgrade Kicks Big, Old Butt
What’s better than a brand new Chevy Camaro Z/28? How about one with Hennessey’s Z/28 performance upgrade? Yeah, that’s what we thought. The Hennessey HPE600 upgrade adds a whopping 131 horsepower to the Z/28, taking it from 505 hp (already impressive) to an even greater 636 hp.
You can see John Hennessey talk about the Z/28 performance upgrade—and then take the Camaro for a spin—in the video below:
Hennessey’s Z/28 performance upgrade includes Hennessey carbon fiber door sills, exterior badging, and premium floormats; HPE engine management calibration and an HPE600 camshaft; ported cylinder heads; redline water weter; serial-numbered dash and engine plaques; stainless steel longtube headers; and upgraded valvetrain parts. The upgrade is professionally installed, as always, and comes with a 3 year/36,000 mile limited warranty. All Z/28s receiving the upgrade will be road tested and dyno tuned before being returned to the customer.
Check out some photos of the Z/28 from the video, fresh out of its upgrade:
