RE: [Chrysler300] AFB 2903 electric choke conversion

[Andy Mikonis <r41hp@xxxxxxxxx>]

My point was to concur with Warren that the heat tubes
serve TWO functions, one is to heat the chokes, the
other is to provide heat to intake manifold/
carburetor for proper fuel atomization.

Independant of choke operation, you still need that
carb heat for proper drivabilty with the engine at
operating temp.  A normal intake manifold on top of
the engine gets heated up by the engine when warmed up
even if the heat riser isn't working.  On a ram
manifold, the carbs are sitting out there cold without
the heat tubes.  They don't run worth a damn that way.
Trust me.  Stalling, popping back through the carb,
etc.

It's why the 400HP short ram F and G's have hot water
plumbed in for carb heat even though they have manual
chokes.  And I hear those cars are still a bear to get
warmed up.
