The engine block had 4.84-inch (123 mm) bore centers, two-bolt main bearing caps, a "side oiling" lubrication system (the main oil gallery located low on the driver's side of the crankcase), with full-flow oil filter, and interchangeable cylinder heads. We've recorded these notes and observations not only for ourselves (because we forget stuff over time), but also in case anyone else can find it useful. The use of restrictor plates, intended as an emergency measure pending a more permanent replacement, in any event, was discontinued at New Hampshire for the following race for Cup only. The Engine size is very large V8 (5.87 liters). The shape of the spacer helps a car funnel more air smoothly into the manifold, increasing fuel performance, while ensuring airflow is still restricted. A Bryant billet crankshaft, identical to a Cup crankshaft, but with a longer 3.600-inch stroke is used in this combination since there is no rulebook on the street.

NASCAR drastically changed its points system for the 1974 season, and it proved to be the most confusing method ever used. These wrecks tend to be singled out for criticism despite multicar crashes at other tracks and the generally greater severity of impact on non-restricted tracks.
