WHAT ARE BIG BLOCK AND SMALL BLOCK ENGINES?

Big block and small block are frequent descriptors of V8 pushrod engines, also called overhead valve engines. Though big-block engines are significantly larger than their small-block brethren, the true difference between these two is more about displacement, bore, and stroke than strictly size. Typically, big-block engines have displacements of greater than 400 cubic inches and small block engines have a smaller displacement.

But because this is the automotive world, and nothing can be quite that simple, there are a few exceptions to that rule that require a slightly more in-depth explanation. There are engines with large displacements that are frequently referred to as small block due to the design of the valves and layout of the cylinders of the engine. The Chevy 396 engine is an example of an engine that has a displacement under 400 cubic inches but is considered a “big block” due to its architecture.

Maintenance of large engine about filter replacement:

1. Increased fuel efficiency
Replacing a clogged air filter can increase fuel efficiency and improve acceleration, depending on your car make and model. When you realise that, it makes sense to regularly replace your air filters.

2. Reduced emissions
Dirty or damaged air filters reduce the air flow to the engine, changing your car’s air-fuel balance. This imbalance can pollute spark plugs, causing the engine to miss or rough idle; increase engine depositions; and cause the ‘Service Engine’ light to turn on. More importantly, the imbalance also has a direct impact on your car’s exhaust emissions, contributing to the pollution of your surrounding environment.

3. Prolongs engine life
A particle as small as a grain of salt can get through a damaged air filter and do a lot of damage to internal engine parts, such as cylinders and pistons, which can be very expensive to repair. That’s why regularly replacing your air filter is so important. A clean air filter is designed to capture dirt and debris from the outside air, preventing them from reaching the combustion chamber and reducing the likelihood of you receiving a large repair bill.
