An engine modification package alters the internal components of a 5.7-liter Hemi engine to increase its displacement to 6.4 liters. This typically involves replacing the crankshaft, connecting rods, and pistons with components that have a longer stroke, thereby enlarging the cylinder volume. The result is an engine with a greater capacity for air and fuel intake.
The primary advantage of this modification is a substantial increase in engine power and torque. A larger displacement allows for greater combustion, which translates into improved acceleration and overall performance. Historically, increasing engine displacement has been a common method for enhancing engine output in automotive applications. This upgrade can offer a cost-effective alternative to purchasing a new, larger-displacement engine, while also allowing for customization and fine-tuning to meet specific performance goals.
