Few engines in GM’s storied history are held in higher regard than the almighty 427 ZL1. And while the old saying is that “You can’t go home again”, we’re not so sure after hearing about GM’s plans on introducing a new 427-inch ZL1 big block in crate engine form.
Ok, quick ZL1 history lesson so everyone is on the same page here. The original 427 ZL1 utilized a lightweight aluminum block and head combo, and was installed in 69 COPO Camaros of the 1969 model year. This little gem even found its way into two 1969 Corvettes as well, generating a good argument that these 2 models are the ultimate Chevrolet muscle!
The new Anniversary Edition of this engine will carry on the legacy of the original. This baby generates 430 Horsepower, 450 lb ft of torque, and features aluminum oval port heads, a hydraulic roller camshaft, and 850 cfm carb. The new ZL1 will be made from GM’s original tooling, albeit with a few updates such as screw-in galley plugs.
Even if you miss this Anniversary Edition, GM will be offering a more economical solution with a regular production ZZ427 crate motor. Now all you need is a Camaro or Corvette to stuff it in.
