One popular modification for a 350 block is to turn it into a 383 cubic inch engine. With a 0.030-over 350 block and a 3.750-inch stroke from a 400 small-block, the result is a relatively simple upgrade.

Can You Make a 383 Out of a 350 Block?

Constructing a 383 out of a 350 block is a popular and relatively straightforward process for enthusiasts looking to maximize their engines power potential. By utilizing a 0.030-over 350 block and combining it with the 3.750-inch stroke from a 400 small-block, it’s possible to achieve a displacement of 383 cubic inches.

The Chevrolet small-block engine, which was produced between 1954 and 2003, is known for it’s versatility and modifiability. This engine series has been a favorite among car enthusiasts for it’s ability to handle modifications and upgrades. The same basic engine block is used in various iterations, with notable improvements and advancements being made over time.

In the case of building a 383, the increased stroke from the 400 small-block creates additional piston travel, resulting in a larger displacement. This extra displacement translates to enhanced torque and horsepower, making it a desirable choice for those seeking more power in their vehicles.

The process involves ensuring that the 350 block is machined to a 0.030-inch oversize, providing enough room for the increased stroke. This allows the use of a longer connecting rod, which helps optimize the engines performance. Additionally, careful attention must be paid to the selection of pistons, rings, and bearings to ensure compatibility and proper fitment.

While building a 383 may initially seem simple, it’s important to recognize the finer details involved in the process.
