COOLING SYSTEM QUESTION

[Bill]

As some of you may know I just put a new radiator in my Vette. It works fine. Wile testing on the hiway at about 70 mph I found that by turning on both fans the temp would drop by 2º C. This leads me to believe that the incoming air is going over the top of the radiator not through it. Last week at “Glass on the Grass” in Tracy I saw a ’92 with a rubber seal between the air cleaner and the hood. Is this seal “stock” I’ve looked in several catalogs and don’t see any.
