A major headacheóthatís what a worn-out engine will give you since it pretty much renders your vehicle useless. When an automotive owner is faced with this problem, the solution that he normally comes up with is to scrap his old car altogether and just get a new one instead. However, not all automotive owners go for that option. Some choose to keep their cars for various reasons and opt to replace the engine instead. And because youíre reading this, you may be in the same boat. An engine replacement may not be the easier path, but if you truly love your old car, then this is the only way that you can drive it again.
Short Block and Long Block Engines: Whatís the Difference?
When youíre looking for a replacement engine, youíd have to decide between getting a short block or a long block assembly. Short block and long block engines are practically alike when it comes to dimensions. The main difference between them lies in the number of parts that theyíre composed of. As you can perhaps gather from its name, a short block engine contains fewer parts than long block engines. Yes, a short block engine still consists of pistons, rods, the crankshaft, and everything else thatís considered part of the engine block. However, the cylinder head isnít included in that assembly. On the other hand, a long block engine is made up of all the components that are available in a short block engine plus the cylinder head. Needless to say, the long block engine is the more complete engine assembly. For that reason, long block engines are more expensive than their short block counterparts.
The Big Question: Go Short or Go Long?
Letís make this simple, eh?
Reasons to go for short block engines:
- All you need is a new engine block
- You want to save cash and use your old cylinder head (given that itís still in good condition)
- You want to optimize performance and apply a little customization (you can pair the engine block with parts of your choosing)
Reasons to go for long block engines:
- If practically all of your engine components need a replacement
- Go for this if you donít have faith in your DIY skills as a long block engine is easier to install than a short block engine
