Down draft tube for 1951 239
 

I have emailed LMC and NPD and MAC trying to find this tube and all I get is sorry. Can anyone advise where to find one?

Hope this gets to the right person

Are you looking to replace the road draft tube for originality or just for function?

Before I swapped my flathead for a 5.0, I machined a plug for the road draft tube and fit a PCV valve to it to pull the crankcase pressure out of the lower end of the motor. My road draft tube was clogged (well the upper half that I had was) and didn't function well. I was experiencing significant blow-by causing minor leaks and smoky exhaust. Once the conversion was done, all the blow-by and smoking was eliminated. It was almost a miracle cure!

If you are interested, here is a link to a similar unit for sale on ebay:

Here is the picture of the one I made (This was prior to installing to test the interference fit so it isn't fully inserted in the manifold)

Road draft tubes have been outlawed in Calif for decades...it is such a source of air pollutants that I would figure that all states have jumped on the bandwagon by now. The rig that OK F1 shows essentially redirects the blow-by from the crankcase back into the air intake flow. Much cleaner solution.
