This standard numbered series engine, equipped with NOS (New Old Stock) HEMI heads, is a collector's dream and a mechanical marvel for any performance enthusiast.
The Boss 429 engine was originally developed for NASCAR racing, but due to strict regulations, it was later offered as an optional engine for select Ford models, including the iconic Mustang and Falcon. The C9AE-E version of this engine is characterized by its cast-iron block, which provides exceptional durability and heat resistance, and its aluminum cylinder heads, which help to reduce weight for improved performance.
The engine's NOS HEMI heads are a particularly exciting feature. These heads are original, unused components that have been stored away since the Boss 429's production run. They are in pristine condition, and their installation on the engine will provide a level of authenticity and historical accuracy that is hard to match.
The Boss 429 engine's 429 cubic inch displacement allows it to produce an impressive amount of power. The engine is equipped with a four-barrel carburetor and a high-compression ratio, which helps to generate a potent 375 horsepower at 6100 RPM and 450 lb-ft of torque at 3800 RPM. This power output is more than enough to propel any vehicle equipped with this engine to exhilarating speeds.
The Boss 429 engine's unique design features include its high-flow cylinder heads, which help to improve air flow and combustion efficiency. The engine also features a high-capacity oil pump, which ensures that the engine's moving parts are well-lubricated and protected, even under the most demanding conditions.
In conclusion, the Ford C9AE-E 1969-1970 Boss 429 engine with NOS HEMI heads is a rare and desirable piece of automotive history. Its powerful performance, authentic components, and legendary status make it an irresistible option for any collector or performance enthusiast.

This engine is Std bore. The heads are a set of used full Hemi to match the engine, they will need building but appear be great. Please feel free to ask any questions thanks. The bottom end might be nos, but can't tell, it has nos Ford pistons in it, the correct Boss 429 part numbered rods and forged crank.
The engine has been floating around for 50 is years so I would 100% take it apart and clean before running, its dirty as can be seen.
