If you’re a casual car enthusiast, you might not care about engine sizes. But if you take your car seriously, it makes sense to want the best performance possible. The more horsepower your engine generates, the faster and more powerful your car can be.
What is the difference between a SBC and a BBC?
SBC and BBC are two different names for the same engine. SBC stands for small block Chevrolet, and BBC stands for big block Chevrolet. Both of these names refer to the size of the engine and its cylinder displacement, not to the type of engine or whether it was made by Chevrolet. A small-block V8 is just as likely to be found in a Pontiac as it is a Corvette or Camaro.
An OHV (overhead valve) engine design has pushrod-activated valves that open at one end only, allowing gases to flow into/out of the combustion chamber during operation–in other words, this design doesn’t use cams like modern engines do. Some versions have intake and exhaust valves located on opposite sides (called “crossflow”) while others have them spaced apart (called “hemi”).
Can You Use SBC Water Pump for big block Chevrolet?
One of the most common questions I get from readers is whether a SBC water pump will also fit a BBC. And while it’s true that these two engines have similar engine blocks and motors, there are still some differences that you’ll need to be aware of before installing one into your vehicle.
It’s important to know what you’re dealing with when installing parts on your vehicle because not all parts fit on every car model or generation. For example, if you try installing a SBC water pump on your BBC (big block chevy), it won’t work properly because they have different valve designs so the water pump won’t fit correctly into place without modifications being made first.
Conclusion
From this discussion, SBC is short for small block Chevy. These engines were manufactured from 1955 to 1998. The BBC is short for big block Chevy. Knowing these factors will help you purchase the right parts that fit your car perfectly.
