..... it is messy...... and caustic......

Or maybe a mild acid solution to dissolve the rust scale overnight???? best done on open (dirt) ground......

Let us know how you Pertronix works...... are you planning to use the matching HD coil at 40K volts??? if so your sparkplug wires may not properly handle it and short out inside the tubes........ with the full coil/Pert. set up you almost need modern high capacity wire......

...and remember no solid core wire...... not recommended by Pertronix.....

Once completed it will run almost as good as a Chev........

Hanno, rather than fill your block back up with shite, flush your block first.
You can use the recently mentioned phosphoric acid or Muriatic acid (mixed with an inhibitor to stop corroding the good bits) Block off your water pumps and fill the engine to the top. If you set up the water pumps so that you can drain it carefully, you can save the acid in a plastic container for future use. You can let it settle and save most of it. Then give the engine a good flush both ways and once you have it all re assembled and sealed up, put a good corrosion inhibitor (+ antifreeze?) in it. Following all safety advice of course!

I agree with all of Bob's suggestions except that he suffers from some sort of schizophrenia as evidenced by his last line.
