Settings for points for 454 engine86 chev c30 scotsdale one ton truck
You have a 1986 454 engine with an old style breaker point ignition distributor, GM has not used a breaker point ignition for their V-8 engines since 1974, is that an older distributor or something after-market?
The ignition points dwell angle for that engine should be set at 29-31 degrees dwell (a dwell meter would be the most accurate way to set the ignition points), or a .019 in. point gap.
The spark plug gap for that engine would be .035 in. and the timing should be set at 10 degrees before top dead center.
