Stock tire diameter Revolutions Per Mile=866.9320 X Gear Ratio divided into the below gives top speed at that RPM

 

7,000 RPM=420,000 Revolutions Per Hour

7,200 RPM=432,000 Revolutions Per Hour

 

Max speed at 7,000 RPM in 6th gear

 

3.909 (stock)               147 MPH (Drag limited to around 120-125 MPH)

4.300 (stock 5-speed)  134 MPH

4.370                                                      132 MPH

4.440                           130 MPH

4.875                                                      118 MPH

5.125                                                      112 MPH

 

Ideal gear ratio would be around a 4.5
