A modification package designed to increase the displacement of a Chevrolet small-block 350 cubic inch engine to 408 cubic inches through an increased crankshaft stroke. The core of this upgrade typically involves a new crankshaft, connecting rods, and pistons engineered to work in concert. These components lengthen the distance the piston travels within the cylinder, thus enlarging the engine’s swept volume and its potential for power.
The impetus for this upgrade lies in the pursuit of enhanced engine performance. Increasing displacement generally results in greater torque output, particularly at lower engine speeds, and a significant increase in overall horsepower. This type of modification represents a popular avenue for enthusiasts seeking to enhance the capabilities of their vehicles, whether for street performance, racing applications, or improved towing capacity. The components included in such kits are often manufactured with improved materials and designs compared to the original equipment, contributing to increased durability and reliability.
