Plymouth Barracuda 440
Although the 440 will always be in the shadow of the all-mighty Hemi, it is a better engine for everyday use. In the Barracuda, it was available in 1969 as a limited production model. But in 1970 it was a regular production option.
With 375 HP on tap, it was less powerful than the Hemi. But in real life conditions, it was just as fast. The 440 was better suited for normal driving and easier to maintain. Yet the Hemi was rarer and more expensive. But if most drivers had to choose, the 440 would be the best choice.
