Big Block

Until the 1955 Chevy, GM produced exclusively big block engines designed for sheer power. But that style of manufacturing had earned the company a reputation for poky, cumbersome cars best exemplified by the famous "Stovebolt Six." Engines such as these were popular. In fact, the 1950 "Blue Flame Six" with its 235 cubic inches set a record by attracting over two million buyers.

But big block engines were clunky and heavy--not ideal for "family" cars. With a little bit of ingenuity, GM was soon capable of producing powerful alternatives in small block styles. These "mouse motors," as they grew to be known, started out at a modest 185 horsepower. Within a few years, however, these V8s could muster up to 315 ponies, as evidenced by the '59 Chevy.

Do You Need a Big Block?

Unless you're a classic car hobbyist or racer, chances are a big block engine is useless to you. Most people simply don't have the space to open up a 1000-horsepower engine anywhere in their neighborhood. On top of that, many big block engines such as the Ram Jet are prohibitively expensive for the average car buff.

If you are in fact taking your hot-rod to shows and competitions, and you have the means to acquire one, a ZL1 is an unbeatable choice. This limited-edition engine is modeled on GM's classic aluminum ZL1 block, and delivers stunning power in addition to drivability. Of course, there are plenty of other more conservative (and less expensive) big blocks out there to choose from.
