USA history of the V8 engine largely pivots around how 'alternative' engine designs were proven during WW2, effectually changing industrial and public opinion. The post-war V8 designs were a component part of automotive styling evolution, allowing a lower, more sleek hoodline.
When Nash and Hudson merged in '54, AMC then was able to make their own V8 engine two years later in '56.
These comparisons are made here to show off the excellent design of AMC's '56-'66 Rambler V8!
