1965 Corvette: Service Bulletin: Corvette Hood Flutter With 425 H.P. Engine
Subject: 1965 Corvette Hood Flutter With 425 H.P. Engine
Model and Year: 1965 Corvettes
Source: Chevrolet Service Bulletin
Zone: #41 - Wichita
Date: July 20, 1965
Owners of early Corvettes with the 425 H.P. engine may experience hood flutter or, in extreme cases, hood rapping on the radiator support.
The rapping noise can be corrected and the flutter reduced considerably by cementing a 1-1/2 foot length of rubber seal, Part No. 3827365, to the top of the radiator support to insulate the points of hood contact.
An identical fix went into production on vehicles built after serial number S116736.
