ABSTRACT:
One or more component braces may be installed into the upper valley of a V-styled engine block to provide resistance to deformation of the block when used in an operating motor. The component braces include first and second mounting portions separated by a body portion, where the mounting portions may be constructed as arms extending from the body portion. An intermediate mounting portion may also be included that is centrally located with respect to the first and second mounting portions, but below a line defined by the first and second mounting portions. The securing of the component brace at the mounting areas provides rigidity to the upper portion of the engine block to resist deformation, such as would occur as relative movement between the cylinder banks. The resistance to such deformation aids in the prevention of cylinder bore wall distortion as well as engine block cracking.
