I believe that's .017 point gap with the automatic transmission equipped 390
I BELIEVE the point gap is ( .017 ) and point dwell is ( 26 - 31 )
.017
Point gap---.017-.019 Plug gap----.034 Dwell Angle-26-31 Timing------10-12 BTDC
The point gap should be set for 30 degrees dwell.
For a 1963 Ford 390 engine, the timing point gap refers to the spacing between the contact points in the ignition system, which is typically set around 0.019 inches. The dwell angle, which determines the time the ignition points remain closed during one engine cycle, is generally set to about 28 to 32 degrees. Properly adjusting both ensures optimal ignition performance and engine efficiency. Always consult the vehicle's service manual for the most accurate specifications.
.019 new points. .017 used points.
should be between .017" and .021"
".016"
.017........Is wrong !The ignition spark gap is .027
For a 1969 Lincoln, the point gap is set at .017, and the spark gap should be set at .035.
