Hi Tony. That carb you have there is kind of rare. It came on Plymouths and Dodges in 1965 equipped with the optional 426, 365 horsepower wedge engines and automatic transmissions! The intake manifold for '62-'66 413,426,and 440s were all the same so fitment should be no problem. You may be able to do this: remove the tube from your valve cover and find a '63-'67 cap with the PCV valve in it and just slip it on. These caps are available as restoration parts. I don't know if the baffling under your valve cover would allow the PCV to work correctly though. You could use a later model valve cover with the PCV valve in it but, as you know, after '63, the valve covers were attached by six bolts instead of four so you would have to seal those extra holes.

On your fresh air, you could buy some flexible tubing, attach one end to your air cleaner and run the hose down to just inside or beneath your bumper. My fear would be sucking up extra sand or dust without a filter down there. As far as ram air goes, Chrysler did a lot of R&D to find high air pressure zones to maximize the "ram-air effect." Placing the scoops or air intake in the wrong area (low pressure zone) would not be effective and not ram anything anywhere. Now you've got me thinking and I might try this myself. Maybe a small engine air filter and housing on the end of the tube would work. Crude, but cheap.

Subject: IML: Carbs and Cool Air

I was wondering if anyone can help on this, I need to know what year and model Chrysler used a Carter 3860S carburetor, I have a spare and was wondering if it interchanges with my 3251S, I want to upgrade to a PCV system instead of the old draught tube setup currently on my car, the 3860 has a vacuum fitting on it, it would save tapping into the manifold vacuum at the brake booster vac line. I know the 3860 has a different linkage setup but that is easy to change to suit the 62 Imp. 

On a similar subject, has anyone tried connecting a hose to the intake on the aircleaner and running it through the radiator support panel alongside the radiator, to pick up cold air, similar to the cold air induction systems on late model cars. On talking to an old mechanic buddy, he seems to think anything along these lines would be better than the hot air from the radiator which is being sucked in now, also there would be the "Ram-Air" effect, which may or may not help performance and economy into the bargain. I figure any increase in economy or performance no matter how small, has got to be an improvement on what we are using now.. New technology and old cars does mix, otherwise we wouldn't have the advances in auto engineering that we have today, after all, if someone didn't try things we would still be driving the gas gusslers of yesteryear as our daily drivers today !!

 

Any thoughts on the subject?
