Engine Block
The anchor for every engine is the block. This component, made from either aluminum or cast iron, houses the rotating assembly, camshaft, timing set, and other components. It also is connected to the cylinder heads, creating the combustion chamber where power is created. Over time, the cylinders and other areas of the block wear from use, requiring repair or replacement.
When choosing an engine block, first confirm the make and engine size you are looking for. Next, choose specifications and options such as bore, lifter, and deck size, rear main seal and main cap types, as well as a block that will work best for your application, whether a daily-driver or drag-race only vehicle. From the remaining compatible options, choose the option that best fits your needs and budget.
