Block Filler & Deck Plugs

What is a Block Filler?

A block filler is a specialized compound used in engine building to fill the water passages within the engine block. It's commonly used in high-performance and racing applications to improve the rigidity and strength of the engine block. Block fillers are poured into the water jacket areas of the block, filling the gaps and spaces. By doing so, the block becomes more stable, less prone to flexing under high loads, and better able to handle increased horsepower and torque. Block fillers also aid in preventing overheating by reducing hot spots and promoting even cooling throughout the engine.

What is a Deck Plug Used For?

A deck plug, also known as a deck plate or engine block test plate, is a device used to temporarily seal the open deck of an engine block during the testing and machining processes. It ensures that the deck surface of the block remains flat and true during these operations. Deck plugs are used to simulate the presence of cylinder heads and to create a uniform surface for measurements and machining. They help in accurately checking deck heights, squaring the block, and verifying the integrity of the block's surfaces before final assembly.

How Much Do Block Filler & Deck Plugs Cost to Buy?

The cost of block fillers and deck plugs can vary depending on factors such as brand, material, and the specific application. High-quality block fillers designed for high-performance engines may cost more due to their specialized properties. Similarly, the cost of deck plugs can also vary based on their design and compatibility with different engine blocks. It's recommended to explore options from reputable manufacturers to ensure you're getting products that meet your needs and performance requirements.

When considering block fillers and deck plugs, keep in mind that investing in quality products is essential for achieving optimal engine performance, reliability, and durability.
