This info was in this forum several weeks ago....just did a "search".
'66 Pickemup truck 250c.i.
AC 46-N spark plug @.035 gap
Point Gap: .019 dwell 31-34 degrees
Timing is 6 deg BTDC
Hot idle speed: standard 500 RPM
Automatic: 'As low as possible to obtain smooth idle and prevent creep in Drive or harsh shifts.'
Idle speed depends on whether or not you have the A.I.R. (smog pump) system.
