Series IV Automatic being set up on a rolling road

[Tim R]

Automatic Sunbeam Alpine being tuned on a rolling road to give smooth powerful performance. There was initially a problem with this car as the manifold design was causing a weakness on cylinder four as the PCD was connected to just one branch. Removing the PCD and allowing the car to breathe to atmosphere transformed the car.
