I found this on another site:
"The following is the tune up and wheel align specs for the 1963 V-8 389
A. single carb,,sprk plg gap-.035,,dist point gap-.016/ Turn Adjusting Screw In (Clock Wise) Until Engine Misfires, Then Back Off Screw 1/2 Turn,,,Dwell Angle 30 deg,,,Firing Order- 18436572,,Ignition Timing-6 deg BTDC/Mark Location-Damper,,,Valve Lash-intake/exhaust-zero,,,Wheel Alignment-caster-( - 1 1/2 ) camber ( + 1/4 ) toe in ( 0-1/8 )
