FAQs—Ford Engine Long Block
- What components are included in a long bock engine? What's the main difference to the short block?
The engine sub-assembly consists of the assembled block, crankshaft, cylinder heads, valve train, and sometimes the camshaft. This comes almost complete. This will require external parts to be installed. The long block doesn't include other parts such as the oil pan, timing cover, calve cover, intake manifold, carburetor or fuel injectors, exhaust manifold, alternator, starter, power steering parts, flywheel, and other electrical components. The short block, meanwhile, has fewer components included in the package since this mainly involves parts of the engine below the head gasket. The short block engine consists of cam pistons, connecting rods, and the crank. Some may also have the camshaft and timing parts. This may require additional internal parts to be installed such as the oil pump, cylinder heads, and gaskets.
- When it comes to initial cost, parts, and labor, which is more expensive: the short block engine or the long block engine?
The long block engine has more parts than the ones included in the short block. Since it already includes the head gasket and cylinder head assembly, this is pricier if you consider the initial cost. To avoid the high cost of the long engine block, some would reuse the head gasket or cylinder heads when replacing an engine. But when considering the cost of the additional parts that need to be installed, it does seem like the short block also asks for a higher price. The cost of the additional internal parts required are pricier compared to the price of additional external parts for the long block engine. The short block also needs more time to be installed, which adds up to the labor cost. When choosing between the long block and short block, the expense isn't just the main consideration. Focus more on the exact needs of the vehicle.
- What are the advantages of using a Ford long block engine?
When it comes to performance, some would say that the long block engine sub-assembly is better since these contain more parts. The say that with more parts included in the block, there are less problems with installation. Also, you're getting almost a complete package.
- Aside from the expense, what's the other important consideration when shopping for a Ford long engine block?
ECU and transmission compatibility should also be on top of the list when exploring this option. The long block engine should work well with the transmission system of the vehicle and the electronic control unit. Also, the engine swap would require parts such as mounts, axles, shift linkages, sensors, and wiring harnesses.
- Which is a better option: the short block or the long block engine?
Although the long block engine is almost a complete package, a motor assembly on its own, this depends on exactly what the vehicle needs. Internal parts or external parts may be damaged beyond repair-this will determine which block would be best. If the cylinder heads and head gasket can still be salvaged and reuse, some would go for the short block engine. Cost will also be a huge factor here.
