When it comes to increasing the displacement of a 350 engine to turn it into a powerful 383, the bore diameter plays a crucial role. Typically, there isn’t a lot of room to go beyond 30 over, although blocks that can handle even 60 over can be identified with the help of a sonic tester. To achieve the desired 383, the block needs to be bored 30 over, resulting in a diameter of 4.030 inches, and a 3.75-inch stroker crank must be used.

How Much Do You Bore a 350 to Make a 383?

When it comes to increasing the displacement of a 350 engine to create a 383, the process involves a careful balance of factors. In terms of bore diameter, there’s limited space to go beyond 30 over, which means increasing the diameter by 0.030 inches. However, with the help of a sonic tester, blocks that are suitable for even larger increases, such as 60 over, can be identified.

In order to further increase the displacement, a longer stroke crankshaft is required. In the case of a 383 build, a 3.75-inch stroker crank is commonly used. The crankshafts stroke refers to the distance the piston travels inside the cylinder, and increasing this distance adds more volume to each cylinder, resulting in a larger overall displacement.

It’s worth noting that this conversion process requires careful attention to detail and precise machining to ensure proper fit and function. Additionally, choosing high-quality components and proper engine balancing becomes crucial to maximize the engines potential and longevity.

The Benefits of Increasing Displacement in an Engine

Increasing displacement in an engine can offer several advantages. Firstly, it allows for more power and torque output, which can result in improved acceleration and overall performance. Additionally, increased displacement often leads to better low-end torque, making it easier to tow heavy loads or climb steep hills. Moreover, larger engines tend to have a smoother operation and produce a deeper and more satisfying exhaust note. Lastly, a bigger engine can provide increased durability and longevity, as it operates at lower stress levels and can handle higher loads more comfortably.


In conclusion, determining the fuel efficiency of a 383 stroker engine is a complex task due to various factors that can significantly influence it’s miles per gallon (MPG).
