It is interesting reading this Thread on Ford Six Cylinder Engine. Did you ever wonder why Ford introduced the OHV version of the 6 Cylinder Engine in 1952, but it was not until 1954 that they introduced the OHV for the V8? That is because Ford Management had decided to cease production of the V8.
Read all about it in this great book:- "The Man who saved the V8" - by Chase Morsey Jr.. It is great reading.
