Will this 71 a833 work in my 68?

the ratios are;
2.47-1.77-1.34-1.00, splits of .717-.757-.746 (the T/A)
2.66-1.92-1.40-1.00, splits of .722-.729-.714 (the regular)
3.09-1.92-1.40-1.00, splits of .621-.729-.714 (the Commando)

I like a second Roadgear of around 6.70. To get that;
the T/A requires 6.70/1.77=3.78 rounds to 3.73s
the others take 6.70/1.92=3.49 rounds to 3.55s .

I like a First Roadgear of not less than 9.5 with a 360, 10.0 with a 340.
To get that;
10/2.47=4.05 rounds to 4.10s, and
10/2.66=3.76 rounds to 3.73s, and
10/3.09=3.23..............

Pick your poison.

I run the Commando with 3.55s
10.97-6.82-4.97-3.55
Cuz 65= 5520 in Second gear.... on a power-peak of about 5200
