Re: 302 winsor that pings with electronic ignition....
The timing may be advanced too far, loosen the bolt at the base of the distributor and adjust the timing with a timing light. If i knew the year and make of your vehicle i may be able to tell you what the timing advance is supposed to be set at. However you will probably find this on an emissions sticker under your hood either on the fan shroud or on the bottom of your hood. hope this helps!

this noise is detonation. It is an uncontrolled untimed ignition from hot spots in the combustion chamber igniting an incorrect air/fuel mixture. IT is harmful if left un repaired as it has the capability of melting holes in pistons.. Run the fault codes or check /change the air/ fuel mixture settings and ignition timing of the engine . Most engines run around 10-12 degrees advanced and any more than that will help cause the problem, as the spark occurs too early and the extra pressure built up by the combustion will combust the rest of the mixture in the cylinder. Fuel quality is important so if you are using a standard grade fuel( 89-91 octane rated) fill with a premium fuel with a higher fuel octane rating . Give a miss to E- fuel mixtures
Yes. I've done it. If you still have the donor vehicle there is an additional vacuum canister in the passenger's fender you'll need (or to plug off the lines) and a few other small additions. Otherwise it's just a straight forward R&R same harness. Please rate my assistance and thanks for using fixya.
Should be right on the side of the engine block, just below the spark plug holes on the right side of the motor. If the motor is still in the car, it will be hard to see. You may also need to clean the dirt and oil off if any exists.
Remove and inspect the spark plugs for heavy deposits or glazed-looking interior insulators. Make sure the plugs are the proper type for this engine. Heavy carbon build-up in the cylinder heads will cause pinging. If the ignition system is too advanced, it will also cause problems. Try a different brand of fuel. High engine temperatures can do the same (caused by poor cooling system or lean fuel/air mixture). If the check engine light is on, take the car to Autozone or a similar business that offers a free scan of the computer. This may provide additional clues. Hope some of this helps!
I am surprised your car has a set of breaker points in it. Someone must have performed an engine swap at some time. You should have an electronic breaker less distributor. But, since you don't set the points gap at 35 thousands. The vacuum supply for the advance should be hooked to a ported vacuum off the carb. It should only have vacuum when the carb comes off an idle. If you hook it to a port that has constant vacuum it will be advanced at all times and will cause engine ping and detonation.
