 Hi - if the bushing is worn, it needs to be replaced. I would not run the =
gear with a thin shim under it, the shim will not last. I just looked at Mo=
ss and they have that distributor bushing listed for $75 plus or minus.
If you have slop with that distributor drive, you will never get the igniti=
on timing to be rock solid.

IMO, if you have too much end float (without packing) you either have a
heavily worn distributor drive gear bush (in the block) or the bottom of
the distributor pedestal which bears against the side of the gear is worn.
I have always had to add some "packing" under the pedestal to get end
float.  BTW, I never found the instructions in the manual a very accurate
way to determine end float.

I'm pretty sure you have to remove the bushing from the bottom, but there
may be a chance to remove from the topside with an inside bearing
puller/slide hammer.  Do not drop the little woodruff key into the engine.

I had a friend turn the pedestal down on a lathe enough to ad shims to adju=
st the clearance and set the clearance with a dial indicator from the botto=
m with the engine turned upside down while on an engine stand.  I think I s=
et it close with something like .0025" clearance. =20

Thanks for all of the responses.  I=E2=80=99ve used this distributor in =
another block, and this is the first time in the =E2=80=9Cnew=E2=80=9D =
block.  In the old block I had the correct clearance without shims so I =
think you are all correct in that I need a new bushing in the =
=E2=80=9Cnew=E2=80=9D block.  The bushing didn=E2=80=99t look obviously =
worn but I guess looks are deceiving!

Thanks again, FOT is great!

Hi - if the bushing is worn, it needs to be replaced. I would not run =
the gear with a thin shim under it, the shim will not last. I just =
looked at Moss and they have that distributor bushing listed for $75 =
plus or minus.

If you have slop with that distributor drive, you will never get the =
ignition timing to be rock solid.
