[Healeys] BJ8 Intake

['bluehealey']

I can confirm there is a wall between runners 3 and 4 in the main runner or
'log'. It has hole of around 5/8" diameter drilled through it presumably to
provide vacuum balancing.

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.

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.
