The creation of this engine was a masterful engineering feat, combining parts from other Chevrolet engines to meet specific racing requirements. The 302 engine featured a four-inch bore, which was the same as the 327 cubic inch engine, and a three-inch stroke, borrowed from the 283 cubic inch engine. This combination resulted in a high-revving engine that was perfectly suited for the track. One of the key features of the 302 engine was its high-lift, solid-lifter camshaft. This camshaft was designed to provide maximum valve lift, which allowed the engine to breathe more efficiently and produce more power. The solid lifters ensured precise valve timing, even at high engine speeds. The engine also featured high-compression pistons, which further increased its power output. The compression ratio was around 11:1, which was quite high for the time. This high compression ratio helped to squeeze every last bit of power out of the fuel. The 1968 Camaro Z28's engine was equipped with a Holley four-barrel carburetor, which was known for its ability to deliver large amounts of fuel to the engine. The carburetor was specifically tuned for high-performance applications, ensuring optimal fuel delivery and performance. The intake manifold was another critical component of the engine. It was designed to provide a smooth and direct path for the air and fuel mixture to enter the cylinders. The high-flow design of the intake manifold helped to maximize airflow and increase power. The exhaust manifolds were also designed to be free-flowing, allowing exhaust gases to exit the engine with minimal restriction. This helped to reduce backpressure and further increase power output. The combination of all these high-performance components resulted in an engine that was incredibly potent for its size. While the official horsepower rating was 290, many experts believe that the engine actually produced significantly more power, possibly in the range of 350 to 400 horsepower.
