Cylinder blocks are normally made of cast iron or aluminum alloy. The aluminum block is much lighter. Various types of materials are combined to increase strength. In the following sections, we will look at the blocks of four-stroke engines.
What is an engine made of?
We make the engine body by pouring molten iron into a mold that is made of sand. (This process is called “casting.”) Other parts are made by forging. In the forging process, a lump of iron is heated red hot and then formed into parts with the desired shape in a stamping machine.
Is aluminum or iron block?
Aluminum makes for lighter and more fuel-efficient engines. Although iron still accounts for 95% of the blocks and 83% of the cylinder heads GM turns out, aluminum is showing up more and more. … A four-cylinder aluminum block weighs about 50 pounds less than the same block made of iron.
What are the types of engine blocks?
The Types of Engine Blocks
- The V Engine. This is probably the most popular engine block on the market and comes in several iterations. …
- Inline Engine. Inline-block engines use a series of cylinders that run in a single line from the back of the engine to the front. …
- Boxer Engines.
Why do cast iron engines block?
Strength: Cast iron blocks are typically stronger than aluminum engine blocks, and they can stand up to higher internal pressures. Power: On balance, iron engine blocks are going to produce more horsepower than aluminum engine blocks.
What is a billet engine block?
A billet is a solid block of aluminum (or any material) with the size depending on the size of your desired part. The larger the desired part, the larger the billet. Contrary to casting, billet parts are created by removing excess material from the billet, essentially the part is carved out of solid aluminum.
Why is billet stronger than cast?
That’s because cast materials are heated and cooled more by the time they become a finished product which changes the structure of the metal itself. … That’s why our billet aluminum housings are stronger than our cast aluminum housings.
What are the 3 main engine systems?

Are engine blocks steel?
Cast iron is used for engine blocks because of its carbon content. It has more carbon that steel, high speed tool steel, and can be harder than some titanium alloys. The carbon content in steel is what makes it hard. Surprisingly enough the content is much lower than you would expect.
How much is an engine block?
Depending on the model being installed, you can expect to pay between $600 and $1000 for small block engines. Depending on the engine manufacturer, you can expect to pay between 1550 and $2500 for a long block engine.
