What is the difference between Ford 240 and 300 head?

Difference between Ford 240 and 300 Cylinder Heads
The Ford 240 and 300 cylinder heads have some differences, primarily in the combustion chamber design and size. The combustion chamber is the main differentiating factor between the two heads.
– The Ford 300 cylinder head has a combustion chamber that measures 76cc.
– The Ford 240 cylinder head has a combustion chamber that measures 68cc.
This means that the combustion chamber in the Ford 300 head is larger than the one in the Ford 240 head. Apart from the combustion chamber size, there are no other significant differences between the two heads.
It is worth noting that the Ford 240 and 300 heads share the same port and valve sizes. However, the Ford 240 head has a smaller combustion chamber, which can result in a higher compression ratio when installed on a Ford 300 engine.
Identifying the Difference
There are a few ways to identify the difference between the Ford 240 and 300 heads:
1. Casting Numbers: The casting numbers alone won’t help differentiate between the two heads.
2. Shape of the Combustion Chambers: The Ford 240 head has a kidney bean-shaped combustion chamber, while the Ford 300 head has a D-shaped combustion chamber.
3. Raised Letter on the Head: Look for a raised letter “A” or “T” on the #6 cylinder end of the head. An “A” indicates a 240 head, while a “T” indicates a 300 head.
It is important to note that these methods may not be foolproof, and it is always recommended to consult a professional or refer to official documentation for accurate identification.
Pros and Cons
The decision to put a Ford 240 head on a Ford 300 engine depends on the specific goals and requirements of the engine. Some potential pros and cons to consider include:
– Higher Compression Ratio: The smaller combustion chamber in the Ford 240 head can result in a higher compression ratio when installed on a Ford 300 engine, which may provide improved performance in certain applications.
– Compatibility: The Ford 240 and 300 heads share the same port and valve sizes, making them interchangeable in terms of fitment.
– Engine Design: The Ford 300 engine was designed with a larger displacement and longer stroke, which may provide more low-end torque compared to the Ford 240 engine.
Ultimately, the decision to use a Ford 240 head on a Ford 300 engine should be based on the specific requirements and goals of the engine build. It is recommended to consult with experts or experienced individuals in the field for personalized advice.
