Valve 350 Chevy Sbc Valve Lash Adjustment Chart

Valve lash adjustment is an important step in maintaining the performance of your Chevy engine. The valve lash refers to the clearance between the valve stem and the rocker arm. If the valve lash is not adjusted correctly, it can lead to poor engine performance, loss of power, and even engine damage.

The Chevy Small Block (SBC) engine is one of the most popular engines used in hot rods, muscle cars, and race cars. The SBC engine was introduced in 1955 and has been produced in many different variations since then. The valve lash adjustment chart for the SBC engine is a useful tool for anyone who owns or works on these engines.

What is Valve Lash Adjustment?

The valve lash is the clearance between the valve stem and the rocker arm. This clearance allows for expansion and contraction of the engine components as they heat up and cool down. If the valve lash is too tight, the valve will not fully close, resulting in poor engine performance and possible engine damage. If the valve lash is too loose, the valve will not fully open, resulting in loss of power and poor engine performance.

Why is Valve Lash Adjustment Important?

Valve lash adjustment is important because it ensures that the engine is running at its optimal performance. If the valve lash is not adjusted correctly, the engine will not run smoothly and can even cause damage to the engine components. A properly adjusted valve lash can improve fuel economy, increase horsepower and torque, and prevent engine damage.
