The distributor on a late model Chrysler 5.2/5.9 does not control
timing, Timing is controlled by the computer which picks it signal of
the fly wheel. When you loosen the distributor housing and turn it, you
are messing with the fuel injection synchronization. After changing
this you need to visit your technition to have your distributor
reindexed to get it back where it was.
