A "six-pack" (three two-barrel Holley carburetors) version of Dodge's engine was added to the offering list mid-year rated at @ 4700 rpm and @ 3600 rpm of torque. The option code for this was A12, which changed the 5th digit of the VIN to M. These special order 1969 1/2 Dodge Super Bees are known as A12 M-code cars. The A12 package also equipped the cars with a Dana 60 axle with a 4:10 gear-ratio, heavy duty automatic transmission or a 4-speed manual, and a 'lift off' flat black scooped hood. Other components to the A12 package included heavy duty internal engine parts, black steel wheels with performance G70x15 tires, and heavy-duty 11-inch drum brakes. Only 1,907 A12 M-code 440 Six Pack 1969 1/2 Dodge Super Bees were produced. This option fell half-way between the standard engine and the Hemi as a USD463 option. The 1969 model year included the base 383 Magnum, 440 Six Pack, and the 426 Hemi. The 440 Magnum (4bbl) was reserved for the Coronet R/T.
