The ENG10 GM Performance ZZ4 Hydraulic Roller Camshaft is a top-tier upgrade for Chevrolet 5.7L V8 engines, specifically model number 5071 and 1252. This camshaft is designed to enhance the performance of your Chevy engine, providing a smoother and more powerful driving experience.
The ZZ4 camshaft is a hydraulic roller design, which means it uses hydraulic lifters instead of mechanical ones. This design reduces engine noise and vibration, providing a quieter and more comfortable ride. The roller design also reduces friction between the camshaft and the lifters, allowing the engine to run more efficiently and with less wear and tear.
The camshaft features a 260/272 duration at 0.050", designed to provide optimal power and torque across the RPM range. The lift is 0.521"/0.521" (intake/exhaust), which provides adequate valve opening and closing for efficient combustion and exhaust. The lobe centers are located at 112 degrees, which helps to improve the engine's breathing and performance.
This camshaft is a direct replacement for the stock camshaft, and it is compatible with Chevrolet 5.7L V8 engines with model numbers 5071 and 1252. It is also a great choice for performance enthusiasts who are looking to upgrade their engine for better power and torque, or for those who are restoring a classic Chevy.
