I have the original cowl air cleaner set up for my 69 350/300 HP however I found that the vent tube under the base is missing. Can someone help me with some ideas to repair this. I really don't want to buy after market just because the vent tube is missing and everything else is in great shape.

Thanks

hedkat, the vent tube for 350s is 1/2". A 327 exterior vent tube is similar to the interior cowl vent tube. You will have to cut it, then JB weld it to the cowl base.

Here is an auction for a 327 ext vent tube.
