Side Scoops: Prominent side scoops were integrated into the bodywork, providing additional airflow to the rear brakes and cooling.

Mach 1 Styling: The Boss 429 borrowed some styling cues from the Mach 1 Mustang, including the iconic “shaker” hood scoop, which moved with the engine’s vibrations.


What truly set the 1969 Boss 429 apart was its incredible performance. Under the hood, it was powered by a massive 7.0-liter V8 engine known as the “Semi-Hemi” or “Shotgun” engine. Some of its performance specifications included:

Horsepower: The Boss 429 engine produced a staggering 370 horsepower, although many believed it to be underrated.
