    7 Blade Fan Part #

    I trying to get my 67 BB to the correct NCRS Specs, I have removed the 7 blade fan and replaced it with the correct 5 blade. I was told that the 7 blade was used for some A/C cars to help with cooling.

    The fan has the following part numbers on it - 914166K76 and 3955182. Does anyone know what this fan is...I believe that it is 17 1/2 inches in Dia.

    Thanks

    The GM #3955182 fan is a 7 blade fan first released for PRODUCTION use in the 1969 model year. It was initially used for some L-36/L-68 and L-46 with C-60. Later, it became the SERVICE replacement for the 5 blade GM #3888366 which was originally used for your car and many other 66-70 Corvettes. The GM #3955182 was NEVER originally used for any 1967 model Corvettes.

        The K76 part of the number 914166K76 would make me think this was produced in November 1976.
