You need to put the computer in "limp mode" You do this by unplugging the timing connector on the firewall. It is Tan with a Black stripe. The bouncing is the computer controlling the timing and with it disabled, you can set base timing. Don't forget to plug it back in when you're done. Paul.

No. It is very Tough on these Models to set the Timing. I had a 87" Scottsdale Also and had the Same Problem. Just takes TLC.

What is the degree setting for a 1977 chevy malibu 305 ( 6?) and which is the number the #1 cylinder?


The timing should be set at 6 degrees before top dead center only for California emission equipped vehicles, and unless the engine code was "CCC" (check the emission label if the vehicle still has one) or had federal emissions then the ignition timing should be set at 8 degrees before top dead center. and 10 degrees before top dead center for high altitude vehicles.

The #1 cylinder is located at the front spark plug on the driver side, and here is a firing order diagram top help assist you.

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.
