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.

454 on chevy won't idle


Did you check your timing? You may have the timing to advanced to compensate for the clogged filter, change your timing and then see if it will idle.
