Details: BBC, 4 Speed, factory console, 3.73 gears, mechanical speedo

Let me know if you need any other details.

A few more details would be appreciated.

How much power will you be making? What is the car's intended purpose? Do you prefer a mechanical or hydraulic clutch? What is your rear tire size? What speed do you typically cruise at on the freeway and roughly what RPM range would you like to be in?
