The engine within Chevrolet’s new Camaro ZL1 was designed specifically to maximize performance. But its precision machining not only boosts horsepower, it also reduces fiction and maximizes the engine’s life.
The process of building the ZL1’s 6.2-liter V8 engine includes a machining process in which aluminum plates are clamped to the block, simulating the cylinder heads, before the final bore and hone of the cylinders takes place. This creates distortions in the block and thus makes the bore slightly out-of-perfect shape.
While the simulated cylinder heads are attached to the block, a boring machine goes to work boring, and then honing each cylinder. This process ensures that each of the cylinder bores are perfect for the engine’s lifetime of piston travel up and down in the bore up to 6,200 times a minute.
“It amazes me what GM does with some of their production engines,” said Andy Randolph, engine technical director at Earnhardt-Childress Racing. “Deck plating is a time-consuming process that fine tunes the bore to get every ounce of power, torque and durability possible. It’s standard practice when building high-end race engines. It tells me the Camaro ZL1 will have some serious performance.”
