A ram-type blowout preventer may include a body, a first ram block positioned within the body and having a first shearing element and a first sealing element, and a second ram block positioned within the body and opposing the first ram block, the second ram block having a second shearing element and a second sealing element. The blowout preventer may also include a load intensifying member coupled to the first ram block, wherein the first ram block and the second ram block are configured to close together upon activation of the blowout preventer, and wherein the load intensifying member is positioned to engage with the second ram block when the first and second ram block close and force the first shearing element and the second shearing element together.
