I need the timming specs in my 1966 buick riviera its got a 425 nailhead single 4.

The spark plug type is 44S and the gap is .032. The ignition points should be set at a 30 degree dwell angle or a .016 point gap. The ignition timing should be set at 2-1/2 to 3 degrees before top dead center, and the engine compression should be 170 psi. Let me know if you require a firing order diagram or any further assistance.

Trying to get timing set i can get top dead center but not sue where sparks plug wire go i know the firing order nothing seems to work htis is on a 1963 ford falcon 170 cid

Here is the firing order diagram for that engine, and the ignition points should have a gap of .025 in. or a 35 degrees dwell angle, and the spark plug gap is .034 in., and the ignition timing should be set at 6 degrees before TDC with a standard transmission, and 12 degrees before TDC with an automatic transmission. If the distributor was removed then it will have to be installed correctly, and let me know if you require any further assistance.

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.

The timing is 2 1/2 degrees BTDC. The point gap is .016 and the dwell is 30. To set the dwell turn the adjusting screw clockwise until the engine starts to misfire and then back it off 1/2 turn. Hope this helps.

Have 78 bonneville.runs fine when cold but when motor warms after about 20to30klms when you give it some gas starts to miss ,timing is right new coils change points and condensers the problem just seems to...

I had a 74 bonny the coils would often times arc out after being warmed up, run the bike at night and proceed to lightly mist the coils and plug wires rev up the mostor and look for arc out spots if none are spotted look into the points you may have the set too close together or the condensors are bad either way the ignition system is breaking down because of the heat factor and it may be somthing as imple as a weak ground connection go through all grounding connections and inspect the wiring harness for kinked wires and do a continuity test acroos the breaker points to ensure proper resistance and continuity, also if new condensors for the points were not provided with points purchase a set.
