Power Rating

We do not have power ratings listed with our transmissions as they will hold up to different amounts of power depending on how they are used. Please call and talk with a sales representative about your driving style and HP to see what will fit your application.

Core Returns

Our T56 Magnum Conversion includes the core cost. We do not require a core return. The only thing that needs to be changed on the car will be the driveshaft yoke to a 31 spline yoke.
