Front Motor Mount System

Several people in the planning stages of their own projects asked me what I did for front motor mounts. The following 3 diagrams show the approach that I took. My main philosophy is to make sure that the weight of the motor and the torquing that takes place when the motor is revved is transferred directly to the ground. The most direct route is through the suspension. In this installation, this turned out to be the only place to put the mounts. (This nice coincidence and several others made me think that the Spitfire was designed to have a larger motor in the future.)

I started with the frame-side motor mounts for a Chevrolet Chevelle. I cut the top parts off of the Chevelle mounts and affixed them to the suspension pedestals of the Spitfire, see the diagrams. It was a very straight forward project and has been very dependable.

The first diagram shows how the stock Chevelle motor mounts were cut to provide the parts that I needed for the Spitfire. The second diagram shows where they fit on the suspension pedestal. The third diagram shows how the motor mount on the engine fits onto the pedestal. Of course there are many more details, but this should suffice to get one started in the planning stages.
