fits model: 283. make: Chevrolet. year: 1955–1963.

( Manufacturer Part Number: 3735236 ), ( Part Type: Block Crankshaft )
The 1955-1963 Chevrolet Block 265/283 Forged Steel Crankshaft, specifically part number 3735236, is a high-quality replacement component for your classic Chevrolet engine. This crankshaft is meticulously crafted from forged steel, ensuring superior strength and durability compared to its cast counterparts.
The 265/283 designation refers to the displacement range of the Chevrolet small-block V8 engines during this era, with the 265 engine being the base model and the 283 being an upgraded version. This crankshaft is compatible with both, providing a reliable foundation for your engine's rotating assembly.
The forged steel construction of this crankshaft offers several advantages. Forged steel is stronger and more resistant to fatigue compared to cast steel, which can be prone to cracking under high load conditions. The forging process also allows for more precise control over the crankshaft's dimensions and shape, resulting in improved balance and reduced vibration.
The crankshaft features a polished finish, which not only enhances its appearance but also reduces friction between the crankshaft and the connecting rods, leading to smoother operation and improved fuel efficiency. The crankshaft also includes a set of new main bearings and a new timing gear for a hassle-free installation.
In summary, the 1955-1963 Chevrolet Block 265/283 Forged Steel Crankshaft is a top-quality replacement part that provides superior strength, improved balance, and reduced vibration. Its forged steel construction, polished finish, and included bearings and timing gear make it an excellent choice for maintaining or upgrading your classic Chevrolet engine.
Pros of buying a 1955-1963 Chevrolet block with a forged steel crankshaft (3735236):1. Durability: Forged steel crankshafts are known for their strength and durability compared to cast iron crankshafts. They can withstand higher horsepower and torque, making them ideal for performance upgrades.
2. Weight Reduction: Forged steel crankshafts are often lighter than their cast iron counterparts, which can help improve engine performance by reducing rotational inertia.
3. Consistency: Forged crankshafts are made from a single piece of steel, which ensures consistent material properties throughout the entire crankshaft. This can lead to improved engine balance and reduced vibrations.
Cons of buying a 1955-1963 Chevrolet block with a forged steel crankshaft (3735236):1. Cost: Forged steel crankshafts are typically more expensive than cast iron crankshafts. The cost of the crankshaft alone can add several hundred dollars to the cost of your engine build.
2. Availability: Forged crankshafts may not be as widely available as cast iron crankshafts, especially for older engines like the 1955-1963 Chevrolet block. This may require a longer wait time or more research to find a suitable replacement.
3. Installation: Installing a forged steel crankshaft requires more precision and expertise than installing a cast iron crankshaft. It is essential to ensure that the engine is properly aligned and balanced to avoid damage to the crankshaft or other engine components.
Conclusion:Buying a 1955-1963 Chevrolet block with a forged steel crankshaft (3735236) can provide significant benefits in terms of durability, weight reduction, and consistency. However, these benefits come at a higher cost and require more expertise during installation. If you are planning a high-performance engine build, the added cost and expertise may be worth it to ensure the longevity and reliability of your engine. If you are building a more budget-conscious or stock engine, a cast iron crankshaft may be a more suitable option. Ultimately, the decision to use a forged steel crankshaft depends on your specific engine build goals, budget, and expertise.
