The Tempest received a redesign in 1964 atop GM's new A-Body platform and provided the base for the original muscle car, the GTO. However, the Tempest LeMans was a good performer in its own right with Pontiac's 326 cubic inch V8. If you want to give your Tempest a big shot in the arm, our A-Body LS swap systems are just what the doctor ordered.
