I have a 60 F100 I will be putting a 302 into.
I am looking at a Tremec TKO500 transmission and it comes in two flavors.
Input Shaft Diameter: 1.125 in.
Input Spline Quantity: 26

or

Input Shaft Diameter: 1.063 in.
Input Spline Quantity: 10

Both have a 31 spline output shaft.
How do I know which would be appropriate for my truck?

The gear ratios are as follows.
First Gear Ratio: 3.27:1
Second Gear Ratio: 1.98:1
Third Gear Ratio: 1.34:1
Fourth Gear Ratio: 1.00:1
Fifth Gear Ratio: 0.68:1

My truck has the stock rear axle which is an 3.70 open differential(non locking).
I have 15 inch rims and do not remember the tire size at the moment but they are not real tall. I am guessing about 5" off the rim.

Will the gear ratio for the Tremec TKO500 above work well with this axle or am I going to end up changing things later? My goal is to be able to take off reasonably quick but have the truck be a daily driver that holds well at highway speeds.

Another option is the TKO600 which has the following gear ratios.
2.87
1.89
1.28
1.00
.64

My engine is 300HP so I thought the TKO600 was overkill but if the gear ratios work better....

I have not decided yet on hydraulic or mechanical clutch. I really like to be able to feel the clutch, it gives me a much better sense of what is going on but am open to opinions.

Thanks.
