Extends Cylinder Wall Life!

Hard Block auto block filler also extends cylinder wall life both by preventing cracked walls and by causing the walls to wear truer, honing is minimized during rebuilds. Remains stable at all operating temperatures and does not soften when exposed to high heat and will not erode under water. Hard Block auto block filler is Non-toxic, non-corrosive and contains no hazardous chemicals.

860228 - Hard Blok Water Jacket Filler is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Works! Hard Block is great to fill water Jackets and doesn't swell block. I called before I ordered and company rep said they poured it in a wine bottle and it doesn't crack it. It takes a large and short fill to completely fill a BBC Mach IV.
