[Healeys] BJ8 Intake

[David Masucci]

Hi Listers,

For reasons I can explain later, I am doing some computer analysis on the behavior of the BJ8 intake tract as it applies to the dynamics of the airflow. Specifically I'm looking at modeling the behavior as the pulses caused by valve closure send waves back into the manifold. I'm looking at how it behaves compared to modern "tuned" runners/plenum manifolds. 

To complete my model I need one more bit of information. Its clear that the front 3 runners and plenum section is a mirror image of the back 3. Does anyone know if the front and back of the plenum section (the rectangular box) is separated by a wall or septum? Or is the front and back wide open.

Thanks,
Dave
