Points are a simple system and do work.

Yes but I can say the same for the electronic pickup once it's installed properly. If you look at the primary and secondary spark on an electronic scope you will see just how good your distributor and points and condensor are. It will show you the spark bouncing if the distributor bearings are worn and it will show you distortions if the points are worn and/or dirty. The electronic sensor is less affected by worn bearings and there are no parts that wear and need to be replaced regularly.

EDIT - The electronic magnetic pickup also is not affected by a worn point cam.

Mike are you talking about timing tab when you state timing tape on dampner? Or do I need something else to set timing?  Ive been thinking of replacing points.  But want to keep original look.  Engine runs fine except when I try to restart after its been running.  It really lugs engine when I restart. When I try to retard timing it kills engine.

It wasn't me that mentioned timing tape but the dampner is the wheel that spins on the crankshaft. It has a timing mark that is a slot cut into the circumference of the wheel. Has that been altered in any way or covered with new markings of any sort? Calibrated/degreed tape maybe?

You can install the Pertronix pickup inside the stock distributor and no one will know but there is no reason that your points can't be adjusted properly. The beauty of the electronic pickup is it's consistency. Your points depend on the distributor bearing being tight and the point cam being good and then they wear quickly. I have no allegiance to Pertronix, any electronic pickup beats points.

Also check the voltage at the battery terminals when cranking. If it is low there then you have a battery problem. If it is holding up there then look elsewhere for your problem.

Maintenance / Re: Short cuts/advice in replacing rear main oil seal
« on: May 12, 2019, 07:01:27 PM »
I did the job on 390 Ford engine years ago and learned a helpful step in the procedure. When you have the pan removed you can make the seal a lot easier to change if you loosen all of the main bearing cap bolts and then bump the engine over by tapping the ignition key.  This causes the crankshaft to drop down just a little making the rear main seal loose in it's groove.

Try this at your own risk but it worked well for me. Maybe only do it as a last resort if you are all apart and having a bad time removing the seal.

General Discussion / Re: 69 Coil Wire Issue
« on: May 12, 2019, 05:58:17 PM »
One way to compensate for the resistance in the car's primary wire is to buy a coil with less primary resistance eliminating any re-wiring.

The pertronix pickup needs to be used with the correct ignition coil resulting in the correct resistance in the primary circuit. A pertronix technician will be able to guide you in choosing the right coil.

If memory serves me, I had to replace a 3 ohm Mallory coil with a 1.5 ohm coil in my stock 68 but then my memory kinda sucks these days.

Unless you are into complete correctness I would install a Pertronix electronic pickup to replace trhe points, set the timing once and forget about it. That's what I did .

I just noticed that you also adjusted the points. That did affect the timing. Setting ppoints at  .030 is OK to start but you should get a dwell meter and adjust them to specs. I think that about 30 degrees is correct but look it up.

As I said, adjusting points will change timing so adjust timing after adjusting points every time.

Mike.

Correction - the point gap should be about .016". which should set the dwell approx. 30deg.

Timing specs are usually stated at a specific rpm. It is normal to adjust idle when adjusting timing.

Turn the idle up so that it stays running and set the timing to whatever the specs are for your engine. Then adjust the idle for about 550 rpm in drive (if automatic trans) or about 800 - 1000 rpm in neutral.  As BillOhio said, don't remove the distributor unless the vacuum advance mechanism is hitting something when you adjust the distributor where you want it.

Have you removed the distributor since you last put a timing light on the engine? If no then I would take the distributor cap off and inspect the mechanical advance mechanism and springs.

Are you disabling the vacuum advance by removing the vacuum hose from the distributor and plugging it up?

I've seen both and those look real to me.

General Discussion / Free cylinder heads
« on: May 08, 2019, 07:43:41 PM »
I have a set of cylinder heads that are free to the first one to pick them up. I'm in south-central Connecticut.

The heads are 3917293 casting number and I believe about 75cc? I removed them from a one-owner 1967 Impala years ago and ran them on my 68 up until a few years ago. They were used on late 1967 Camaros.

The castings are fine but I would rebuild them.

What condition are the front right pads in? Is the caliper piston over-extended?
