The B/FX class in drag racing stands for "B Factory Experimental," a category from the 1960s era of drag racing governed mainly by NHRA (National Hot Rod Association). B/FX was part of the broader FX (Factory Experimental) classes, which were created as a venue for American car manufacturers to showcase and experiment with high-performance vehicles not confined by the strict limitations of stock production rules. These classes were hugely influential in shaping modern drag racing.
The B/FX class produced some legendary vehicles, like the 1965 Mercury Comet B/FX, which often featured powerful, factory-boosted V8 engines, special cylinder heads, and highly tuned carburetors and camshafts.
This class, along with its A/FX and C/FX counterparts, fueled fierce competition among Ford, Mopar, and Chevrolet, leading to iconic "drag wars" at the strip that played a significant role in the development of muscle cars.
