Generally in that model year, the stock gear ratio with automatic transmission was 3.36:1, and I believe that this ratio also applied to the 3-speed manual. The more common 4-speed gearing used with the high-performance 409 was the well-known 4.11:1.

My speedo is 20 miles per.hr. slower than I'm really driving, rear end and tranny both look original .

@1964impala. if your Impala has the shifter on the column it is not an SS. SS had shifter on the floor / bucket seats. Regular Impala had full bench front seat.
