Packard engine swap
Packard's straight eight was envied by most other auto people at the time for it's large 327 displacement, providing more power than the competition's smaller 250 or 300 cid designs. The inline design was formerly accepted to be the most dependable engine design, whereas the Packard inline eight placed the power of eight cylinders upon a nine main bearing crankshaft design, part of the early history argument against a V8 design was the idea of putting the power of eight cylinders onto a five main bearing crank = not enough bearing area, would wear out faster. This is partly why the early US V8 engine designs were typically considered to be 'overbuilt' and heavy, with comparatively small cid; the early V8s were matching the displacements and weights of the earlier I8 designs, aiming to have the same durability. Flat head inline engines were made to keep the vehicle's center of gravity lower, and to reduce the engine height for a lower profile hoodline, all component parts in the historical evolution of US automobile history. Interestingly enough, most new V8 engine displacements have evolved back to those early inline eight displacement sizes, the more powerful new V8s being somewhere around 327 cid, or 5.4L.
