Ford 390 V8 Engine

The 390 V8 engine was first introduced in 1961 and was Fordís chance to jump ahead of the all new Chevrolet 409 that was introduced later the same year. The Ford 390 produced a lot more horsepower than the 409 with its top end performance engine putting out a respectable 401 horsepower in its first year of production (41 more horsepower than the high end Chevy 409). The 390 was used by Ford and Mercury in a large amount of their production cars as well as several trucks. Unfortunately most car enthusiasts were more excited about Chevroletís 409 simply because of its larger size which diminished a lot of publicity for the Ford 390. Even today the Chevy Impalas with a 409 sell for twice and even three times the amount than a Ford Galaxie with a 390. Plus the Beach Boys never wrote any songs about the 390 V8:-)

Today the 390 is still a very popular motor due to the fact that it is very easy to get parts for these engines that can easily push the horsepower into the 500+ horsepower range if the motor is built for racing.
