The factory code for the 1969 Dodge Super Bee 440 Six Pack package was A12.
Introduced midway through the 1969 model year, the A12 package transformed the Super Bee with Chrysler’s 440-cubic-inch V8 fitted with three two-barrel Holley carburetors. Dodge rated the engine at 390 horsepower, positioning it between the standard 383 Magnum and the more expensive 426 Hemi.
A12 cars also received a Dana 60 rear axle, heavy-duty components, performance gearing, special steel wheels, upgraded brakes, and a lightweight lift-off hood with a functional air scoop. The package changed the fifth VIN digit to M, which is why these cars are often called “M-code” Super Bees. Dodge built 1,907 A12 Super Bees for 1969½.
A common mix-up is confusing A12 with R/T, which was a separate Dodge performance designation, or W-30, an Oldsmobile engine package. “Six Pack” described the three-carburetor induction system; the factory option code itself was A12.
