The ZL1 Camaro was reintroduced in 2012. The original ZL1 Camaro is likely the most legendary vehicle in a long and storied history of Chevrolet muscle cars.
The ZL1 name is derived from the all-aluminum racing engine of the same name, which was developed in the late 1960s and
installed into a handful of regular-production 1969 Camaros. And by handful, we mean there were only 69 built with the engine,
each representing the pinnacle in Camaro performance.

Although only 69 ZL1s slipped out GM's doors, the ones that did were the fastest cars GM would sell for decades to come.
The name of the all-aluminum 427 V8 became synonymous with what remains one of the most potent Camaros to ever leave the factory.

The ZL1 Engine was never intended to be put into a street legal production car. Chevrolet had developed the engine primarily
for Can-Am racing and other track use under the hood of a Corvette. Featuring aluminum heads used on the also potent L88
iron block 427, the ZL1 also featured an entirely aluminum casting of the 427 engine block. The combination resulted
in an engine that was rated at 435hp and weighed about the same as a small block 327.
