[Spridgets] Cement in the engine?

[BJNoSHOV8]

This makes sense.  It sounds like what the construction industry uses 
called "metallic non-shrink grout".  Even though it is based on portland 
cement, it has been formulated to have different properties and these 
properties would make it more appropriate for use within engine block 
water jackets.
