Side Oiler Vs Top Oiler: Which is the Superior Engine Choice?
The main difference between a Side Oiler and a Top Oiler is the oil flow path – the Side Oiler sends oil along a passage located on the lower side of the block first, while the Top Oiler sends oil to the top center first. This difference affects the lubrication of the engine components.
The Ford FE engine, which includes the Side Oiler and Top Oiler variants, has gained popularity among car enthusiasts for its unique design and performance capabilities. We will explore the characteristics of the Side Oiler and Top Oiler engines, as well as the reasons why enthusiasts may prefer one over the other.
Whether you’re a car enthusiast, a collector, or simply curious about the differences between these two engines, this article will provide you with the essential information you need.

What Is The Difference Between Side Oiler And Top Oiler?
Blocks were cast in two major groups: top-oiler and side-oiler. The top-oiler block sent oil to the top center first, the side-oiler block sent oil along a passage located on the lower side of the block first. To keep the crankshaft happier at the top of the rev range, Ford added a special oil passage along the left side of the block to direct oil to the crank first, and then the cam and valve train.
A center oiler has no superior aspects to a side oiler, except being somewhat less expensive. For street use, a center oiler probably has no reasons for a side oiler. The side oiler feeds the mains first but requires one to check if it has the cross-bolted mains.
Advantages Of Side Oiler
The Side Oiler engine offers several advantages over the Top Oiler counterpart. Firstly, it ensures improved oil flow to the crankshaft, resulting in better lubrication for high-rev applications. This means that the engine can operate at higher speeds without experiencing excessive wear and tear.
Additionally, the Side Oiler design enhances overall engine performance by optimizing oil distribution throughout the engine block. This allows for more efficient functioning of various engine components, resulting in improved power and efficiency. Whether you’re a car enthusiast or a performance-driven individual, the Side Oiler engine is a great choice to enhance your vehicle’s capabilities.
With its superior oil flow and enhanced lubrication, it offers unparalleled performance and reliability for all your automotive needs.
Advantages Of Top Oiler
The advantages of a top oiler engine include efficient oil distribution to the cylinder heads, enhanced cooling for the valve train, and better reliability under extreme conditions. With a top oiler, oil is sent to the top center first, ensuring that all the cylinder heads receive an adequate amount of lubrication.
This helps to prevent any potential damage or overheating issues. Additionally, the top oiler design allows for better cooling of the valve train, which can be crucial for high-performance engines. The top oiler also offers improved reliability, as it ensures that oil reaches critical components even in demanding situations.
Overall, the top oiler design provides several benefits for engine performance and longevity.
Comparison Between Side Oiler And Top Oiler
Blocks were cast in two major groups: top-oiler and side-oiler. The top-oiler block sent oil to the top center first, the side-oiler block sent oil along a passage located on the lower side of the block first. To keep the crankshaft happier at the top of the rev range, Ford added a special oil passage along the left side of the block to direct oil to the crank first, and then the cam and valve train.
This new oil passage from the side of the block resulted in a new name, the side oiler. A center oiler has no superior aspects to a side oiler, except being somewhat less expensive. For street use, a center oiler probably has no advantage over a side oiler.
The side oiler feeds the mains first but requires one to check if it has the cross bolted mains.
Which Engine Should You Choose?
When it comes to selecting between a Side Oiler and Top Oiler engine, there are several factors to consider. The main difference between these two engine types lies in the oiling system. The Top Oiler block sends oil to the top center first, while the Side Oiler block sends oil along a passage located on the lower side of the block first.
The Side Oiler design, with its dedicated oil passage, ensures better lubrication for the crankshaft and valve train. However, the Top Oiler is often considered more cost-effective and suitable for street use. Your choice ultimately depends on your specific use case and preferences.
Whether you prioritize performance or budget, both engine types have their own advantages and considerations.
Frequently Asked Questions For Side Oiler Vs Top Oiler
What Is The Difference Between Side Oiler And Top-Oiler?
The main difference between a side oiler and a top oiler is how they distribute oil. In a side oiler, oil is sent along a passage located on the lower side of the block first. In a top oiler, oil is sent to the top center first.
How Can You Tell A 427 Side Oiler?
A 427 side oiler can be identified by the presence of a pipe plug and hump on the side of the block. It also has pipe fittings on the side.
How Much Horsepower Does A Ford 427 Side Oiler Have?
The Ford 427 side oiler has a high horsepower output.
Why Is The Ford 427 Called A Side Oiler?
The Ford 427 is called a side oiler because it sends oil along a passage located on the lower side of the block first.
Conclusion
Both side oilers and top oilers have their unique advantages and characteristic features. The main difference between the two lies in the way oil is circulated within the engine block. While top oilers send oil to the top center first, side oilers direct oil along a passage on the lower side of the block first.
This new oil passage in side oilers ensures better lubrication to the crankshaft and then to the cam and valve train, resulting in improved performance. On the other hand, top oilers may be considered less expensive and are a viable option for those focused on street use.
When choosing between a side oiler and a top oiler, it is essential to consider your specific needs and intended usage. Both types have their merits and can deliver impressive results. Ultimately, the decision will depend on factors such as personal preferences, budget considerations, and the desired level of performance.
Whether you opt for a side oiler or a top oiler, both engine types have their respective devotees and can be reliable choices for automotive enthusiasts.
