A performance upgrade package designed for specific Ford small-block engines, notably the 302 cubic inch (5.0L) Windsor, increases the engine’s displacement to 331 cubic inches. This is achieved by using a crankshaft with a longer stroke, along with matching connecting rods and pistons. The result is a significant boost in torque and horsepower compared to the original engine configuration. An example would be installing this kit in a classic Mustang to enhance its acceleration and overall power.
The implementation of this enhancement offers several benefits, including increased low-end torque, improved throttle response, and greater overall power output. Historically, modifications like this were pursued by automotive enthusiasts seeking to maximize the potential of their engines for racing or street performance. The ability to increase displacement within the existing engine block provided a cost-effective alternative to swapping in a larger, more complex engine.
