R/T,
The fastest A-Body production (non-race car)
These A-bodies are listed with the available options.
The "M"-Code was a 'Special Car Order'. Production numbers list #360 produced and/or #343. No one knows for sure.

69' 440 Cuda, fastback, (A-727 automatic transmission only).
Came standard with 3.55 gears, the 3.91 and 4.10 were both options.
10" Drum brakes standard
Car weight #3279. The car had 197 lbs. of more weight in the nose, than the 340 Cuda..
The exhaust system was still somewhat restrictive, despite an improved
driver side cast iron exhaust manifold.
No power steering, manual only. The bolt pattern was still the smaller
5-bolt/4" bolt pattern. Wheels 14" x 5 1/2", available with only
E-70" x 14" Red-streak tires.
You did not have to order this car with the Formula 'S' package, as it came through with the heavy-duty suspension package.
(Heavy-duty torsion-bars (.89" thickness 120# rated, white stripe label), Heavy-duty front sway bar,(15/16" thickness), Firm-Ride 1" shocks, Heavy-duty 6-leaf rear springs, and Sure-Grip rear-end.
Car Life Magazine tested 13.89 @ 103.2 mph
Major problems off the line, no traction, due to nose weight and small
width tires.
With 4.10 gears and good traction, with a capable driver,
13.35's @ 108 mph.
In 1969, with 7" slicks, they would be classed in C/SA (8.50-8.99 wt/hp).
1969 C/SA National Record; 12.24 @ 114.06 (Dave Duell, 1963 Dodge Model #440 station wagon 426/425HP Stage II Max-Wedge)
