the 1100 ci all aluminum  was originally built for aircraft, but it was way to large and under powered.
  It was used in many US tanks... 500hp,  that is a general view of the engine

52 Lincoln????  I did read of a monster V8 that Ford supposedly built for tanks in WWII  that was an overhead.

As far as the 52 Lincoln, Ford probably decided to build it around 1950 or so as they plan 2-3 years ahead of production

Wikipedia doesn't show it as an overhead, but lists  the 52 Lincoln as a Y Block

I was just wondering if anyone knew of when Ford decided to built it's first OHV engine,
including the Lincoln line. Can you give a website for reading?
thanks
