By dwell use a meter 28-32 degrees
To change points in a distributor, first, disconnect the battery to ensure safety. Remove the distributor cap to access the points, and then take out the old points by loosening the screws that hold them in place. Install the new points by aligning them properly and tightening the screws, ensuring the gap is set according to the manufacturer's specifications. Finally, reassemble the distributor cap and reconnect the battery.
To set the dwell on a 326 Pontiac, you'll need a dwell meter. First, connect the dwell meter leads to the appropriate terminals on the ignition coil or distributor. Start the engine and let it warm up to operating temperature, then rev the engine slightly to stabilize it. Adjust the distributor's points gap until the dwell reading is within the specifications, typically around 30-34 degrees for a Pontiac V8.
I remove the distributor and rotate until the points are at the widest opening. Then using a .017mm fueler Gage I set the point gap. Reinstall the distributor, set timing and roll!
i always had a meter with dwell on it you adj your points base and keep the gap the same Addition to above: Haven't messed with a points ignition in quite some time, but still have a Sun distributor machine and remember how to do it, if it's a dual point distributor the easiest way is to block one of the sets of points with a matchbook cover or thin piece of cardboard in between the points and set the dwell on the other set, then put the matchbook cover between the point set you just set the dwell on and set the dwell on the other set, then remove the matchbook cover and your done. If you're doing this on the car (as opposed to doing it on a distributor machine) you should then re-set or at least check the timing.
if you googlehow to set points on distributer the first answer is correct, with the cam lobe on the shaft opening the points it should open to 17 thousands
To set the distributor on a 455 Pontiac, first ensure that the engine is at top dead center (TDC) on the compression stroke for the number one cylinder. Align the rotor to point toward the number one cylinder terminal on the distributor cap. Next, insert the distributor into the engine, ensuring it seats properly and the rotor aligns with the terminal. Finally, secure the distributor and adjust the timing with a timing light to the recommended specification.
If you set the points at 30 degrees you will be fine.
To replace the points in a 1939 V8 flathead, first, disconnect the battery to ensure safety. Remove the distributor cap and rotor to access the points. Unscrew the old points, noting their orientation, and install the new points in the same position, ensuring the gap is set to the manufacturer's specifications. Finally, reassemble the distributor, reconnect the battery, and test the ignition system.
If you have a dwell meter set the points between 28 and 32 degrees, I usually set them right at 30 degrees.
your distributor is not set right. its probably in backwards by 180 degrese
To change a dual pickup distributor to a points distributor on a Chrysler 318 motor, first, remove the existing dual pickup distributor by disconnecting the ignition wires and the mounting bolt. Next, install the points distributor in the same position, ensuring it aligns properly with the camshaft. Connect the ignition wires according to the firing order and set the ignition timing as required. Finally, adjust the points for the correct gap and ensure everything is secured before starting the engine.
A 1983 engine doesn't have points, but if you have changed to a points distributor use the same timing settings that were used with the original distributor. if you can time an engine with a hei dist. it's the same way with points. you have to use a timing light, and turn the dist. to retard ,or advance the timing. If the engine has been fitted with a GM type distributor there should be an access door to the side of the distributor cap. Use a "dwell tach" (with the engine running) to set the dwell, then use the timing light to set the timing. If it's not a HEI ignition then it's safe to assume that it's not EFI either so you'll set the timing by loosening the retaining bolt at the base of the distributor, then turn the distributor to align the timing mark with the amount of advance indicated for your altitude. The timing light will cause the mark to appear that the dampener pulley has stopped and you will be able to move the mark as you turn the distributor. NOTE! When setting the timing always remember to disconnect the vacuum line.
