Did you know there was an adjustment in the vacuum cannister where the vacuum hose from the carb port goes! If you remove the vacuum hose, you can insert a 3/32" allen wrench in there and turn it clockwise to lessen the vacuum and counterclockwise to increse it! This is one of the best,take you by you're hand and do it right instuction tutorial i have seen! Lot's of awesome info! http://www.sweptline.com/tech/engine2.html Good luck!
 
 
Excellent Glenn
 
That is true.  But not ALL advances have it. 
 
FYI  Aftermarket advances usually don't have that feature

Added octane boost....Lucas the best stuff money can buy 8.00/bottle still pings....retarded the timing just a couple lines....still pings....Now I'm thinking about getting rid of the points...going to electronic ignition...What do you guys think?

Points or solid state - makes no difference - has no effect on why it's pinging.  Maybe the distributer but not because it's points.

The old man is right. 
 
It's either running too lean or the timing is still too far advanced.  The only other option is it's running way too hot.  But I think you'd know that.
 
Is it pinging real bad or just slightly?  Back the mixture screws out 1/2 a turn and see if that helps.  It will answer a few questions. .  .

Steve, Before I retarded the timing (not sure of the scale-2 fine lines from TDC is that -8 BTDC ?) the pinging was slight .....while going up grades at 50MPH....engine fully warm...I could here just faint pinging...I could get rid of it by giving it gas....Now after retarding to -8 BTDC...that slight ping going up grades is gone...but it pings bad when I give it gas....engine still fully warm....Now....I'm wondering if this is the issue. I'm still running Prestone Super engine flush...I'm at about 6 hours of run time....The bottle said 6-8 hours of run time then dump it and add the 50-50 antifreeze/water mix. The pinging in both cases is with engine at running temp. Maybe the pinging will subside with fresh coolant? All the pinging does occur after running engine 1/2 hour +++. I certainly can back off on the mixture screws but I didn't want to try too many things all at once...(I remember you said that a while back) Maybe I should do that next before changing anything else. Thanks guys...

Only one variable at a time when running any experiment, strict science protocol.

Retarding the timing will cuase the engine to run warmer than normal.

How about the thermostat I have in there? I'm not sure what temp it is. Should I get a new one...lowest temp they sell?...or what would happen if I had no thermostat? Just no heat right?? but it would run cooler....correct??

No thermostat could make it run hotter.  The thermostat is used to keep the water in the Rad longer to get coolar. 
 
You can't go too cool.  `80 ought to be sufficient.  What is the condition of the radiator?  Is it all clogged up?  Might be time for a recore.
 
I know Polaraco runs nice and cool all the time.  In fact, it runs cold in the winter.  To the point where I freeze my can off.  It doean't reach full operating temps

Thanks Steve...When you said '80...Did you mean the 180 degree thermostat? If I remember right, I think my choices was a 180 or 195 thermostat...The guy at AutoZone says the 195 is standard equipment. What will make it run cooler...the 180 or the 195...? I know this may be a "duh" type question...but for some reason (especially after your explanation of how a thermostat makes the engine run cooler) I have it in my mind that it might be the higher temp. thermo. to make it run cooler?? No..Yes?

The guy at Auto Zone is wrong.  The standard back then was 180.
 
Typo. . .Yes 180

Thanks Steve ol' buddy ol' pal. You are the Head Kahoona!...One last question...Since I'm removing the thermostat...is that a good way to flush the system? Remove it and keep flushing till it runs out clean...or should I just get one of the heater hose in-line T's with the cap on it. What would be more effective at getting the crap outa there? I don't like leaving the in-line T in there...looks hokey and I don't trust them either...Thanks

If I may, let me jump in here.
First, buy some kind of cooling system cleaner.  The more caustic, the better. 
Remove your thermostat and reinstall the housing.
Drain the radiator. Close the petcock.
Disconnect heater hose return line and direct it away from the car.
Set heater to "high temp"
Run garden hose into radiator.
Start her up and run until water flushing out of heater hose is clean.

I don't recall - how is the condition of your radiator?  If it's plugged, flushing won't help.  Is it new; does it need a rod-out?  A bad radiator will defeat all of the flushing, new thermostats, time adjustment, and any attempt to stop pinging.
