I really wonder why no one suggests a ball bearing. I run ball bearings 
in all Panteras for years with out any issue.

My experience was similar to Julian's.  I was a long time advocate of
using pilot bushings verses bearings .  It was driven by a needle
bearing pilot failure in another vehicle.  Why take the chance?

However, I began hear a scrub noise emanating from the ZF bellhousing
upon hard starts from a standstill.  Switching to a needle bearing
remedied the problem.

I believe that line boring the block moves the crankshaft center-line
slightly off axis from the ZF input shaft.  The pilot bearing is more
forgiving on the input shaft nose to the misalignment.

I would suggest one consider a bearing if their block has been line
bored and they do not have the gadgets to properly install offset dowels
to recenter the ZF bellhousing to the block.

    I believe Marlin and some of the vendors sell them.

    I was always an advocate of the oilite until I got my GT5; Coz had the
    ZF rebuilt and it was fresh back from Dennis Quella, in fact Coz and
    I installed it when I picked up the car from him and I then proceeded
    to drive from Phoenix to Reno non stop (other than gas). The car wasn't
    shifting quite correctly and we got Dennis to drive the car at the
    Pahrump track during the Fun Rally, he agreed it was still not shifting
    correctly. I then pulled the ZF and sent it back, Dennis went back
    though it and could find nothing wrong, however he sent it back with a
    needle bearing and said try that for the pilot. Low and behold that
    fixed all my problems, so now I'm a convert to the needle bearing and
    never had an issue since.

    It would be interesting to see if Lloyd Butfoy's opinion aligns with
    Dennis on the needle bearing vs. oilite
