Dodge Super Bee std specs: 383 ci (6.3L) 8-cylinder, 4.25 x 3.375 in (108 x 85.7 mm) bore and stroke. Rated 335 hp, 1968–1970. Used in the Dodge Coronet. OHV.
The Dodge Super Bee std is oversquare — the 4.25" bore exceeds the 3.375" stroke by 25.9% — a layout that favors airflow and RPM over leverage at the crank. The 3.375" stroke does not reach 4,000 ft/min of mean piston speed until about 7,100 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 8 cylinders displaces 47.9 ci (785 cc).
It is one of 9 engines in the Dodge 383ci family, all of them 383 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions, rated at 335 hp across 1968–1970.
