A 4.84 Bore Space Motor is a type of engine block that has a bore diameter of 4.84 inches (123 mm) between the cylinder walls. This size is commonly used in performance engines, and can accommodate larger bore sizes than standard factory blocks due to its thicker deck surface and wider main bearing journals.
These motors have become popular for their ability to support higher compression ratios and increased power output compared to smaller bore space engines, making them ideal for drag racing applications or other forms of high-performance driving.
A 4.84 Bore Space Motor is typically machined from aluminum alloy billets or castings with improved cooling features such as water jackets, deeper oil pans, and windage trays added as desired by the manufacturer or owner/builder.
A 4.84 bore space motor is a type of performance engine block that has been designed with larger cylinders and increased displacement for greater power output. This motor is typically used in drag racing applications, as the extra space allows for more air and fuel to be burned, resulting in higher horsepower ratings than standard engines.
Additionally, this design can accommodate large camshafts and other modifications that increase airflow even further.

What Does 4.84 Mean in Drag Racing?
Drag racing is one of the most popular motorsports in the United States and around the world. In drag racing, cars race down a straight track for a set distance, usually about 1/4 mile (1320 feet). The goal of each driver is to get from point A to point B as quickly as possible.
One way racers measure their performance is through elapsed time or ETs. This measures how long it takes a car to finish the course in seconds; this number is then rounded off to two decimal places such as 4.84 seconds. When both drivers have similar vehicles and conditions are equal, that number can show who had better reaction times at launch or who had superior vehicle performance throughout the race.
That difference between two drivers’ ETs may be only 0.02 seconds but those few milliseconds can make all the difference in winning or losing on any given day!
What is Engine Bore Spacing?
Engine bore spacing, also known as cylinder center distance, is the distance between the center of two adjacent cylinders in an engine. It is measured from the centerline of one cylinder to the centerline of another and dictates the size and shape of an engine’s combustion chamber.
Bore spacing is important because it affects how much power can be generated from a given displacement without increasing compression ratio or valve sizes.
In addition, larger bore spacings allow for more efficient cooling since there will be less heat concentrated around individual cylinders. Finally, wider bores also result in improved bearing wear since they provide more support for crankshaft journals and reduce vibration levels during operation.
Engine manufacturers often use different bore spacings depending on their requirements; some may opt for a smaller diameter that allows greater fuel efficiency while others might favour larger diameters with increased power output capabilities.
Ultimately, it’s up to each manufacturer to decide which combination of factors works best for their specific application needs.
What is the Bore Spacing on a 5.3 Ls?
The bore spacing on a 5.3 LS is the distance between the center of each cylinder in the engine’s combustion chamber. It is measured from the center of one cylinder to the center of an adjacent cylinder, and it is typically expressed in inches or millimeters. The bore spacing on a 5.3 LS engine is 4.400 inches (112 mm).
This means that each piston will sit 4.400 inches apart from its neighboring piston when viewed across both cylinders at once, resulting in an even distribution of air/fuel mixture throughout all cylinders for optimal performance and efficiency.
As such, this bore spacing has become increasingly popular among modern engines due to its ability to provide excellent power output while still remaining efficient and reliable over time with proper maintenance and care.
What is the Bore Spacing on a Bbc?
The bore spacing on a big block Chevrolet (BBC) engine is 4.84 inches, which is the distance between the centerline of each cylinder in the engine’s cylinder bank. This measurement has remained unchanged since its introduction in 1965 when the first generation of BBC engines were released.
The term “bore spacing” can also refer to the distance from top dead center (TDC) to bottom dead center (BDC) for any given piston stroke or crank throw as well as other related measurements such as deck height and valve length.
BBC engines are known for their large displacement, high performance capacity, and extreme durability that have made them popular powerplants for muscle cars, boats, drag racing vehicles and more over the years.
