Interesting placement of the heat riser--is that factory or after-market?

Pete,

    There is no "heat riser" on this car.  The vacuum fuel pump is factory mounted on the intake manifold but (not being used in this example).  Also note the unused connection on the exhaust manifold where a flex tube would originally be connected to the heat jacket on the original Marvel carburetor.  The original parts to preheat the gas/air mix are not connected, so this car does have an aftermarket "stove" mounted on the exhaust pipe to provide pre-heated air to the carburetor intake.

Mark and Pete,

 

Mark, you are right, there is/was no heat riser for this carburetor.  What you guys are seeing is a 'heat muff' that was held to the exhaust pipe by a single J bolt.  The muff had a flexible conduit that connected to the carburetor intake.  This was factory equipment on the early production cars that used the old style intake manifold.  There was a Hot Air Coupling that connected the flexible conduit to the intake manifold.   This set-up is indicative of the early production units, however, this car has the crowned fenders and the combination switch in the dash uses a tumbler lock instead of the barrel key.  These were features that came along later in the production year.  Who knows!
