How do you set the timing on an 83 350 with points type distributor?
A 1983 engine doesn't have points, but if you have changed to a
points distributor use the same timing settings that were used with
the original distributor. if you can time an engine with a hei
dist. it's the same way with points. you have to use a timing
light, and turn the dist. to retard ,or advance the timing. If the
engine has been fitted with a GM type distributor there should be
an access door to the side of the distributor cap. Use a "dwell
tach" (with the engine running) to set the dwell, then use the
timing light to set the timing. If it's not a HEI ignition then
it's safe to assume that it's not EFI either so you'll set the
timing by loosening the retaining bolt at the base of the
distributor, then turn the distributor to align the timing mark
with the amount of advance indicated for your altitude. The timing
light will cause the mark to appear that the dampener pulley has
stopped and you will be able to move the mark as you turn the
distributor. NOTE! When setting the timing always remember to
disconnect the vacuum line.
