Auto to manual , pilot bearing question

The swap will lose the first gear TC torque multiplication going to a manual trans. To make it up you will need to add about 10 to 20% more gear to the diff. And that will bring the cruise rpm up the same percent.
The 198 cannot afford to lose that TC. I know you can slip the clutch out higher, but that gets old in a hurry. If you are looking for a little more pep, there are other ideas.And easier too. And probably less expensive too.
Honestly, I don't see this as a good thing to do.I know you didn't ask for an opinion, but .....
But in answer to your question, it is a non issue. If the crank won't accept the tranny, you simply cut the input shaft off a bit and switch to a ball-bearing pilot.
