Found the manifold leak, but....

So ;

? Is the knocking gone ? .

One of the great things about these sturdy, well designed work horses is : they'll run just fine with badly worn out everything, for decades, as long as you keep it sharply tuned and full of clean oil .

If you don't mind the blue smoke just set the dwell to 33 degrees then the idle timing to 10 degrees BTDC @ 700 or less RPM's and no vacuum to the dizzy .

If it begins to foul spark plugs, just get an original Delco HEI distributor, install it and open the plugs to .050" and it should keep on running just fine for years .

The knocking is gone! The plugs look fine! I’ve thought about dropping in an HEI dizzy - now that the carb is right the truck idles fine and doesn’t spit, sputter and/or die when I give it gas and let out on the clutch. No (noticeable) smoke from the exhaust. Points/condenser ignition systems work fine if one is willing to piddle with them regularly...and I’ve self-diagnosed me as a piddler.

Just so Sir ;

If it's good to go don't worry just take care of it .

I've become a faithful believer in breaker less ignitions, be they HEI or just simple Pertronix Ignitors .

All one needs do is : check the timing every oil change and drive happy.....
