Eagle has a reputation for well-built engine components, and this assembly is no exception. The Pro Street line is specifically designed for racing applications where reliability and performance are paramount. The I-beam connecting rods offer a good balance of strength and weight for their intended use, while the pistons are sized to match the bore and stroke for optimal compression and power. This assembly is balanced, which is a critical step in ensuring smooth engine operation and longevity, especially at higher RPMs.
When undertaking an engine build of this caliber, it's important to ensure all components are compatible and installed correctly. This assembly is intended for naturally-aspirated racing use and is not CARB approved, meaning it cannot be shipped to California.
