The 1978 Trans Am typically came equipped with a Rochester Quadrajet carburetor. This four-barrel carburetor was commonly used in many GM vehicles during that era and was known for its performance and efficiency. Depending on the engine option, the specific tuning and jetting of the Quadrajet could vary. Some models also offered the option of a Holley carburetor, but the Rochester is the most prevalent for that year.
In 1978, a total of approximately 11,000 Chevrolet El Camino Conquista models were produced. The Conquista trim was known for its distinctive features and upscale options compared to other El Camino variants. The 1978 El Camino was part of the second generation, which ran from 1973 to 1987.
