Pilot Bearing ?

I am searching for a 360 magnum for a future project. (87 dakota ) But my question is, can I use a magnum engine out of a truck that came equipped with a automatic transmission? I will be puttting a NV3500 transmission behind it.
In searching the internet, I have found 3 answers.
1. It will work fine, they all, are machined for the pilot bearing,
2. Some are machined .020 too small, and have to be machined to accept the bearing.
3. Some were not machined at all.
This site seems to be the most accurate I have found on magnum swaps so I value and appreciate any input.
Thanks for your help.
