The 51-000-9 Pontiac 400/455 Mechanical Roller Camshaft Comms is an exceptional upgrade for any Pontiac engine enthusiast seeking improved performance and reliability. This camshaft is specifically designed for the 400 and 455 cubic inch engines, making it a perfect fit for classic Pontiac muscle cars such as the GTO, Catalina, and Grand Prix.
The 51-000-9 camshaft features a mechanical roller design, which provides several benefits over traditional flat tappet camshafts. Mechanical roller cams reduce friction, resulting in less heat generation and longer camshaft lifespan. They also offer improved valve control, resulting in smoother engine operation and improved throttle response. The roller design also provides more consistent valve lift, which can result in increased horsepower and torque.
The 51-000-9 camshaft is a comp cam, which means it has a larger lobe profile than a stock camshaft. This larger lobe profile allows for more aggressive valve movement, which can result in increased power and performance. The camshaft is designed with a 252/256 duration at 0.050-inch lift, and a 0.540-inch lift at the valve. This design provides a good balance between power and drivability, making it a great choice for both street and track use.
The 51-000-9 Pontiac 400/455 Mechanical Roller Camshaft Comms is made from high-quality materials, including heat-treated steel and chrome molybdenum alloy pushrods. The camshaft is also equipped with high-quality roller lifters, made from sintered bronze, which provide consistent valve timing and reduced noise.
Installing the 51-000-9 camshaft is relatively easy, but it does require some knowledge of engine tuning and installation. It is recommended to have the camshaft installed by a professional mechanic to ensure proper installation and tuning.
In conclusion, the 51-000-9 Pontiac 400/455 Mechanical Roller Camshaft Comms is an excellent upgrade for any Pontiac muscle car. It provides improved performance, reliability, and drivability, and is made from high-quality materials that will last for years to come. Whether you're looking to take your Pontiac to the track or just want to improve its daily driving performance, this camshaft is a great choice.
