C69A Ultrasonic Cylinder Thickness Test

[52Allard]

There has been some question / mystique about Canadian engine cylinder walls being thicker or better material. Not sure about the material question but I did find a C69A engine block for a project I'm working on and thought I'd share the ultrasonic test with the rest of the Ford community.
The measurements are taken in 4 X,Y directions in the cylinders from the top of the cylinder and down about 4 inches from the top. My block is standard bore with some wear (I'd guess .005" to .008" on the worst walls). The technician recorded the thinnest reading of each quadrant on the sheet. Looks to be mostly over .2" but a couple of locations at .17" - fortunately not on a thrust surface.

What are you guys seeing for cylinder wall thicknesses for a US made 59A engine block?
