Hard Blok Short Fill Engine Block Filler Water Jacket Grout 14 lb Pail V8 860212

Hard Blok Short Fill is a cement-based water jacket filler that is poured into the lower part of an engine block’s water jackets. Once it cures, it backs up the cylinder walls and the main web area, so the block is stiffer and the bores hold their shape under high cylinder pressure. Because only the lower jackets are filled, coolant still flows through the upper block, which makes the short fill a good match for street/strip, circle track and drag engines that still need a working cooling system.

The mix uses a cement base with size-graded iron particles, made to expand and contract at the same rate as cast iron once cured. It will not shrink, wash out or go soft after it sets. Hard Blok has been making block filler since 1986.

Features

• Short fill – fills the lower water jackets only, so coolant can still circulate
• Supports the cylinder walls and main webs to cut bore flex and distortion
• Helps keep ring seal under load and reduces block vibration
• Cement and iron formula matched to the expansion rate of cast iron
• Does not shrink, erode or soften once cured
• Works in cast iron and aluminum blocks
• Sized for most small-block and big-block V8s – Chevy, Ford, Mopar, Pontiac and Oldsmobile
• Suited to builds up to roughly 700+ hp that still run a cooling system

What’s in the box

One 14 lb bucket containing two 6.25 lb bags of filler.

Note: Filling the water jackets is known to raise internal oil temperature, so keep an eye on oil temps after installation.
