2.48x2.61x4.56 =29.51 Turbo 400 with NP208

2.48x1.96x4.56 = 22.16 Turbo 400 with np205

You forgot to calculate the "torque converter" and tires. The multiplication factor in our torque converters should be 2.5:1 . That is assuming you have the factory 6 bolt torque converter. So in first gear at a dead stop till about 5 mph you have max multiplication. As you go faster the multiplication factor goes down until at about 30 mph where you have a 1:1 ratio.
