Unnatural adaptations.

YOur comment about the possible need to install 4-valve heads onto "approximately similar" four cylinder blocks due to a possible fuel crunch got me thinking...

When reviewing the 427 block prints a week ago, ref a reduced resolution image here:

I noticed the cam bearings are spaced on 1/8" wider centers (4.75") than the bores or mains (4.63"). This seems very odd. This does, however, explain the "offset oil holes" which lead into the cranksaddles.

I wonder if this allowed Ford to make cams using the same machinery which cut MEL cams. I guess I gotta look to see whether Ford offered any engines with 4.75" bore centers about that time. Also, I'll have to see whether there is always a discrepancy in any engine, as this variation may provide a necessary function.
