My Blitz's

[Bob Carriere]

I am runnign a Chev 261 in a cab 11...... I have connected the stream line and a turn off valve.

Now everyone one knows that 261 have extra steam relief holes in the head/block.

I ran my engine using a clear vinyl line....... you run the engine to full operating temp.... about 160 degrees..... not hot enough for steam.

You run the engine for a while and when you open the valve..... the line filled with green antifreeze turn white with froth moving to the radiator...... after a while the line goes full of green fluid again. My conclusion is the engine can used it even if it is a modern 1959 chev 261. When I redid the line with the proper steel line and rubber connector... I removed the valve and am now running with the line fully open.

what did they know in 1940 that we don't know now....?
