I wonder if they are "drip"pans or heat shields to prevent percolation
of the gas in the carburetors after shut down? Which car is this? I have a close up picture of the twin carburetors on the Duesenberg Special and
it has a bigger "drip"pan or heat shield than this one shows.

I bet your right Bob, heat shields not drip pans. The moment any gas hit those shields it would evaporate. Of course evaporating gas is what burns!
That looks like a lot of carb. flow for even a Duesenberg. What do you think Bob?

Those brass carbs for the SJ are pretty rare. You see mostly the truck carb version of the UU-2.

Mike,
Randy Ema told me the twin carb SJ's didn't run smooth at low speeds and I often thought they would dump a lot of gas into the manifold(s) if
the engine had the "rams horn"system. I think if I were going to mosify a "J"about all I would do would be to bump the compression up a couple of points and use two carbs on seperate manifolds. Maybe Randy will expand on this thread if he has time.

The twin Carb photo is 292 Le Baron dual cowl and orig they would have drip pans with a drain pipe and heat shields.

It is nice to see the spit polish I put on them 30 years ago is holding up :)
