Every modern V-8 is a varation on the Cadillac V-8.
Dr. Charles Kettering's 1949 design outline; oversquare bore/stroke, shaft rockers, wedge combustion chambers, siamesed center exhaust ports, separate intake manifold/valley cover and water manifold/water pump, five main bearings, long connecting rods, near-horizontal intake flange, long exhaust ports, was followed by Cadillac, Oldsmobile, Studebaker and Packard, but not by all of the first-generation 1949-55 V8s. From 1951-58, Chrysler did not choose the wedge combustion chamber or the siamesed exhaust ports; a hemi chamber, opposed valves, dual rocker shafts, alternating intake and exhaust ports were much more efficient and thus had a performance edge for the next ten years.
No, By 1955 the second generation of GM engines changed dramatically, choosing ball/stud rocker arms, using the intake manifold as the valley cover and the water manifold as the water pump housing, much shorter exhaust ports, shorter connecting rods, thus made for a very different engine internally and externally.
Maybe, but the current generation of OHC V8s and the GM pushrod V8s only retain the oversquare influence and five main bearings. Nothing else remains from Kettering's 1949 design.
