And from the Summitracing web site:


Hard Block has the optimum ratio of graded iron for strength and vibration
dampening. Its thermal coefficient is nearly identical to cast iron, and
also proven to work in aluminum blocks. It won't shrink nor pull away from
cylinder walls. It is stable when exposed to water, anti-freeze, and high
temperatures. It is available in a pre-measured Short Fill (12.5 lb.)
container to partially fill the jackets of your street or Oval Track engine,
or a Tall Fill (28 lb.) container for drag racing.

Used in the Water Jacket of drag race engines.


>From the Jegs web site:

Hard Blok (Water Jacket Filler) is a specially formulated, cement-based
material that provides maximum strength, vibration dampening and heat
dissipation required in high-performance race engines. 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.

What exactly does "in the engine" mean? Are you filling the water jacket, or
the crankcase? Displacing either water or oil seems like a really bad idea.
I think you need both.
