2. 289 V8 Small Block
Introduced in 1963, the 289 CID, 4.7-liter V8 engine was a small block unit Ford designed to be an entry-level V8 for all models in their lineup. With small dimensions, a relatively small weight, and decent power, the 289 engine was an impressive offering for car buyers. It was available on all Ford Motor Company models, from the modest Falcon to the upscale Galaxie 500. But, the 289 proved to be a perfect match for the legendary Ford Mustang, which they introduced a year later, in 1964.
In the Mustang, this engine was an ideal combination that suited the character of the car. Even in its base variants with a single dual-barrel carburetor and 200 HP output, this small 289 V8 engine provided an impressive performance to the iconic Mustang. Ford recognized the potential of this engine and upgraded it to a 221 HP. Next, they produced the 271 HP and then the legendary 289 HiPo, or High Power version. The HiPo 289 was a factory-tuned engine that featured the same displacement but with tougher internals, an intake system, and a four-barrel carburetor.
The 271 HP provided a lively performance in the Mustang GT; however, the ultimate 289 came in 1965, thanks to the famous Carroll Shelby. The Shelby American company built a racing Mustang called the Shelby GT350. Under the hood was a race-ready 289 engine with a totally different intake, cylinder heads and pistons that delivered 306 HP from 4.7 liters.
The final year for the 289 Mustang was in 1968 when Ford replaced it with more modern engines. Over the years, Ford has produced millions of those small but powerful engines that have become a favorite with Mustang owners. Ford still makes the parts and aftermarket components for the 289 V8 today.
