HardBlok® 860228 - Engine Block Filler

Engine Block Filler by Hardblock®. Comes in a kit. HARD BLOK Water Jacket Filler is a specially formulated, cement-based product with refined, size-graded iron particles combined at an optimum ratio to provide maximum strength, vibration dampening, and heat dissipation required in high performance race engines. Its coefficient of thermal expansion is identical to cast iron engine blocks. Product has been tested and proven effective in aluminum blocks.
