Engine Replacement: What’s the Difference Between Short Block and Long Block?

Need to replace your engine? When you visit your trusted auto repair shop in Madison, TN, you’ll likely have two options for replacement: short block and long block. The names are a bit misleading, since both engine types are similar in size. The components they carry, however, are very different from each other, and there’s a lot riding on which option you choose. Here’s what you need to know about the differences between these two engine types.

Short block engines

Short block engine packages usually include the engine block, crank, pistons and connecting rods, and it gets its name from its short list of components and short warranty. These are the basic components that are critical to a working engine. In some cases, short blocks can come with extras like camshafts and timing belts. When you visit your auto repair shop in Madison, TN and choose a short block as your replacement engine, keep in mind that you’ll need to purchase additional parts, including gaskets, cylinder heads and oil pumps.

Warranties on short blocks only cover the parts included in the original purchase, not any extras like the parts named above. The warranty doesn’t cover faulty fittings, which means professional installation from a reputable mechanic is necessary to ensure the longevity of your engine replacement investment.

Long block engines

Long block engines get their name from the fact that they have a longer list of components. They contain the engine block, crank and pistons, just like the short block, but they also have a cylinder head, camshaft and valve train. In some cases, you’ll also get an oil pan and valve covers with your purchase.

Which engine should I choose?

Long block engines are generally best in situations where your vehicle needs a complete engine overhaul. You’ll get better reliability and performance from a long block vs. a short block. Always ask your trusted mechanic whether a long block is compatible with your vehicle’s electronic control unit and transmission system.

Short blocks are generally cheaper than their more complete counterparts, but you need to keep in mind that they’re more likely to malfunction. Another cost associated with short block engines comes with maintenance. The age of the components in your engine will be varied if you choose a short block, so some parts will wear out faster than others and require replacement. The choice of additional components like cylinder heads isn’t necessarily a bad thing, though, because you can select quality external parts that boost the short block’s engine above that of a long block.

There are many considerations to keep in mind as you select the right engine replacement options for your vehicle. Do your research to find the perfect fit in terms of price and performance, and always get your replacement fitted by a professional technician at your trusted auto repair shop in Madison, TN.
