It will sleep allright. A 2.41 with an overdrive...having a final ratio of 0.69 will give an effective final ratio of 1.66. Nothing is gonna pull a gear that tall.
A t 350 or 400 would be Ideal.
If you run an overdrive, you need a 3.55 or lower(3.73 or 4.11) to run it.
Many machine shops a can cut , shorten, phase and weld your shaft probably for 75 or 100 bucks. Get the one you have sliced down and forget it.
