Auto to manual , pilot bearing question

225 is nearly 14% larger, than the 198.
Torque multiplication inside the TC can be as high as 2.2 ratio.

Let's say the 225 makes 80 ftlbs at 1800stall, into a 2.76rear and 2.45low and 2.2TC. That makes 1190ftlbs.
Let's say the 198 makes 80/1.14 =70 ftlbs into the same 2.76rear and 2.66 low and ZERO stall(cuz it's a stick-car), so have to slip it out to the same 1800 = 514 ftlbs.
The 198stick would need 1190/514 x 2.76to have equivalent starting torque. That would be a 6.39 rear; (or plus 231%)
But let's say the factory 225-Tc can only muster a 1.5 ratio. The new number is 811 ftlbs. To compare, the 198stick would then need 811/514 x 2.76 =4.36s, (which is plus 58%)
But let's say the factory 225-Tc was exceptionally weak at 1.2 multiplication. The new 225 number is 649tlbs. To compare; the 198stick would need 649/514 x 2.76 =3.49s(plus 26%)
But let's say the factory tc had a big fat Zero torque multiplication. The new number is thus 551 ftlbs. To compare, the 198stick would need 551/514x 2.76 =2.90s, (Still plus 5%)
As for me, there is no way I would put a stick behind a 225 in an early A, never mind behind a 198 in a lwb Dart. That is just waaaay too much time and work, for,IMO,no good reason.
But hey, OP, just do it and report the results.Please.

But let's say you put the 3.09box behind that 225. The new 225numbers are 80 x 2.76x 3.09=597 ftlbs. How you(nm9) could find that "no problem", as compared to 1190...............IDK
But then again the stall-ratio is an instantaneous and fleeting phenomenon.
