Cast Iron (Fixed Flow)
The number of the Fuel Distributor's cylinders do not necessarily have to match with the engine, if the Fuel Distributor has more cylinders.
An 8CYL Fuel Distributor can be used with a 6CYL engine, a 6CYL Fuel Distributor can be used with a 5CYL engine, etc. This is done by leaving the extra cylinders of the fuel distributor un-drilled; for example, an 8CYL Fuel Distributor would have two cylinders not drilled (or muffled channels) to fit a 6CYL engine.
