Interesting Things with JC #1630: "The 392 HEMI" – Inside the 392 HEMI, air is pulled across a wide hemispherical chamber as the piston drops, but the same layout that improves high-RPM cylinder filling also makes the engine wider, hotter, and harder to package, carrying a 1901 combustion design through Chrysler racing dominance and into a modern 6.4-liter V8 that still depends on airflow instead of boost.
