Speedtech Performance USA LSX engine adapter plate motor mounts were produced for the top-performing and smooth-running power plant--the LS engine swap. They are a simple and effective way to install one of these engines in an older muscle car. These mounts are manufactured and CNC-machined from 6061-T6 billet aluminum and finished off in a classic black powdercoat for a long trouble-free finish. They are simple to install and an easy step to get your early model car up to late model speed.
