You are forgetting the rear gear plays into it as well. With the T-56 you can swap rear gears and get where you want to.

MT82 1st 3.66 * 3.55 stock MACh gear = 12.99
T56 1st 2.97 * 4.30 rear gear = 12.77

or

MT82 5th 1.00 * 3.55 = 3.55 [2.30 overall in 6th]
T56 5th .74 * 4.56 = 3.37 [ 2.28 overall in 6th]

The tighter gear spacing of he T56 will keep you in the power band better than the bigger spacing of the MT82. This is why the 10 speed automatic is so much faster than he manual in the newer cars. The rpm stays in the sweet spot. Depending on your setup you just use the rear gear to tune he operating range.

For me the T56 and 4.10s would the way to go. The 3650's 3.35 with 4.10s is a little much and then I could pop it in 6th and cruise the highway lower than stock rpms.
