Swapping an LS engine into a classic GM A-body is nothing new. UMI Performance LSX engine mounts allow the installation of an LS engine directly into your A-body. By retaining the proper angle of the engine, you keep your pinion angles/drivetrain operating smoothly. This is a good reason to get pre-engineered mounts for the swap instead of trying to make something work. These mounts place the engine in the factory location, but also give you the ability to relocate the engine rearward up to 3/4 in. or forward 1/4 in. UMI's LS engine mounts will bolt directly to your car's frame and the LS block without modifications. Their brackets have greasable polyurethane mounts to dampen vibration, but still provide a solid feel and eliminate the need for additional modification when using the LS1 oil pan. New premium mounting hardware is also included. Getting a quality set of mounts designed for your application will definitely make the swap a lot easier
