A complex machine meant to convert heated fuel into the force that turns your car’s wheels, the engine is truly the heart of your car. There are many engines on the market, including short-block and long-block options. If you’re looking into Chevy crate engines or any other type, it is important to understand what each kind does and the key differences between them.
What Is a Short Block Engine?
A short block engine is the basic formation of a vehicle’s engine. In addition to the cylinder block, it includes other critical components such as the cam pistons, crankshaft, and connecting rods. Each engine manufacturer has its own way of packaging short block engines. Some of them come with other parts, such as the timing belts or camshafts. However, most of the required additional parts need to be purchased separately.
What Is a Long Block Engine?
A long black engine provides everything a short block one does but includes many more of the components you’d need to buy separately if you purchased a short block. Long blocks feature the camshaft, valve train, cylinder head, and lifters. They may even come with valve covers, a water pump, and an oil pan. Even with the additional components, though, a long block doesn’t include everything you’d need to rebuild your engine. Additional purchases may include the intake manifold, electrical components, fuel system, and exhaust manifolds. When engine shopping, keep in mind that “small block” and “big black” are not interchangeable for “short block” and “long block.” “Small” and “big” refer to engine size while “short” and “long” refer to how many of the assembly parts are included.
What Are the Costs and What Warranties Are Available?
The amount of money you’ll spend and how well-protected your purchase is are important considerations when choosing the right engine. Short block engines are typically cheaper than long block ones, although factors such as make, model, and year of the car are important as well. On average, short blocks are $1,000-$3,000 while long blocks are $1,500-$5,000. Keep in mind, though, that you’ll need to purchase more items separately when you purchase a short block, which could drive up the price considerably.
Warranties are important as well. Long block engines often have longer and more comprehensive warranties than short block ones. Remember, warranties only cover initial purchases, so a short block warranty won’t cover any of the parts you had to purchase separately. Additionally, neither type of engine covers faulty fittings, so if you aren’t sure how to install an engine, calling a professional is essential.
Which Engine Is the Right One?
The type of engine you choose depends on your budget, your skill level, and how much work you are willing to do. Short block engines are best for people who want to learn how to build an engine on their own since it’s a hands-on approach. Long block engines are better for those who want to get the job done quickly. Additionally, long block engines often perform better and are less likely to malfunction since many of the parts were preinstalled.
Whether you’re installing a new engine or an electric exhaust cutout, always do so responsibly. Buy from reputable manufacturers and hire professional mechanics if you aren’t adept at engine building yourself. This ensures your car is safe and reliable on the road.
