I did a bit of "looking" before I changed from my toploader to the TKO600.

Dispite all of the advice you are going to get and there could be much more than this, what you really need to ask yourself is what do you intend for the car.

If you are going to be drivning around town taking on all comers, you may wish to play the gears out for a lower top end that screams to go 80.

Then again, if you are looking for touring about and will see upper speeds, you may elect to use gears that allow for milage ( especially in this day and age ) at cruising speeds without a loss of performance.

It all comes down to intention and design of the car, what are YOU going to do with the car.

There are threads that will tell you about what they did and how they feel about what they did.

May I recommend you determine your intent. There are a good number of cobras that are NOT drag cars and have very respectable topends. There are also a number of cars that are 7 sec street machines.
