Claim:
1. A wall block comprising: a block body having opposed front and rear faces, opposed and substantially parallel top and bottom surfaces, and opposed first and second side walls that converge from the front face toward the rear face such that a total surface area of the front face is greater than a total surface area of the rear face; at least one core extending from the top surface to the bottom surface, the at least one core having opposed front and rear surfaces and opposed first and second side surfaces, the front surface of the core being positioned in closer proximity to the front face of the block body than the rear surface of the core and the first side surface of the core being positioned in closer proximity to the first side wall of the block body than the second side surface of the core; at least a first and second pin hole opening onto the top surface and the bottom surface of the block body and extending the distance from the top surface to the bottom surface of the block body, the first pin hole opening onto at least one surface of the at least one core through a first core slot and the second pin hole opening onto at least one surface of the at least one core through a second core slot, the first and second core slots extending the entire distance from an uppermost top surface to a lowermost bottom surface of the block body, the first and second pin holes having a maximum lateral width as measured in a direction from the first side wall to the second side wall, the first and second core slots having a maximum lateral width smaller than the maximum lateral width of the first and second pin holes along the entire distance from the uppermost top surface to the lowermost bottom surface of the block body, such that each pin hole is sized to accept a pin and each core slot is sized to retain the pin in the pin hole and to prevent displacement of the pin into the core; and at least a third and fourth pin hole opening to the top surface and the bottom surface of the block body and being closed to the at least one core, the third pin hole being positioned between the first side surface of the at least one core and the first side wall of the block body and the fourth pin hole being positioned between the second side surface of the at least one core and the second side wall of the block body.
