They are not the same engine. the Ford 10 cam runs in the iron bore of the block, the 100e has shell bearings and a water pump, different oil pump, different head. Some parts are interchangeable. I finally got my answer from Ford Sidevalve Engine services. They also could not find it in any of their manuals so they measured 2 engine blocks and came up with 1.666" for the cam bore dia. Thanks to all, Fred

I have a Ford 10 engine that I am trying to salvage. It has worn out cam bearings and I want to install 100E cam shells. My question is what is the diameter of the cam bores on a 100E engine? I cannot find this dimension anywhere. Thanks, Fred V
