Some metal content, (barely)...This started last spring actually when
I helped a driver in an '69 olds 442 convertable that died on the
roadside.


If I had to guess, I'd start with the ignition, if you find the idle
mixture is about right - with the higher compression the ignition is more
critical - put the stock Dist back, new plugs and new wires (and dist cap,
etc) and see if it's better.

As crazy as it sounds, I would swap out the coil, even with a used one, just
to check. I have seen ignition coils do some really weird things.

Please let us know what you find out. I love to hear stories of mechanical
puzzles. Seem far to many of them.
