COPO Camaro News: Official Spec Sheet Released! - LSX Magazine (2)

The COPO Camaro is officially on its way, and it won’t be long until these beasts start tearing up a drag strip near you. To tide us all over until these killers start showing up in the hands of the lucky 69 folks who got to purchase one, our friends over at GM Performance Parts sent us over a little sneak peak at the COPO Camaro’s official spec sheet. It lists everything from the power numbers for each engine combo down to the specifics of the suspension set up. It’s all laid out below in detail, straight from GM Performance Parts.

We won’t spoil any of the surprises here, but one of the real shockers is the “shipping weight” of the COPO Camaro. How does just 3,200 pounds sound? Check out the Official COPO Camaro Spec Sheet below for yourself and let us know what other specs stand out to you.
