Scat Crankshaft 4-350-3480-5700 Machined 3.48in Stroke Crankshaft

Description

Product Overview

Scat Crankshafts has built a reputation for delivering high‑quality engine components, and the 4-350-3480-5700 model continues that tradition. This crankshaft features a precision‑machined exterior that provides a smooth, durable surface for optimal bearing contact and reduced friction. With a 3.48‑inch stroke, the crankshaft is engineered to increase leverage and torque output, making it an excellent choice for performance‑oriented builds. The component weighs only 0.01 ounces, yet its robust construction ensures it can handle the stresses of high‑rpm operation without compromising reliability.

The part number 435034805700 corresponds to a machined steel alloy that balances strength and weight. Its dimensions—26.25 x 9 x 9 inches—fit a wide range of V‑type engines, and the package dimensions of 24.79 x 9.24 x 11.02 inches make shipping and handling straightforward. The crankshaft’s design incorporates Scat’s proprietary heat‑treatment process, which enhances fatigue resistance and extends service life. Whether you are rebuilding a classic muscle car or upgrading a modern performance engine, this crankshaft provides the foundation for a powerful, smooth‑running powertrain.

Usage

This crankshaft is suited for a variety of high‑performance applications. It excels in street‑legal performance builds where drivers seek increased horsepower without sacrificing drivability. In racing environments, the lightweight yet strong design helps reduce rotating mass, allowing the engine to rev more freely and respond quickly to throttle inputs. The 3.48‑inch stroke is ideal for engines that benefit from a longer lever arm, delivering higher torque at lower RPMs, which is valuable for drag racing and off‑road competition.

Installation is straightforward for experienced mechanics. The crankshaft fits standard Scat engine blocks and aligns with common bearing sets, reducing the need for custom machining. It is also compatible with aftermarket performance camshafts and pistons, making it a versatile centerpiece for a complete engine upgrade. Whether the vehicle is a classic American V8, a modern sports car, or a custom hot‑rod, this crankshaft provides the reliability and performance needed for demanding driving conditions.

FAQ

What engines are compatible with this crankshaft?

The 4-350-3480-5700 crankshaft is designed for a range of V‑type engines that use standard Scat block dimensions. It fits many classic American V8s as well as modern performance builds, provided the engine block matches the specified bore and stroke requirements. Always verify clearance with your specific pistons and connecting rods before installation.

How should the crankshaft be installed?

Installation should be performed by a qualified mechanic. Begin by cleaning the engine block and checking all bearing surfaces for wear. Apply the recommended assembly lube to the main and rod journals, then carefully seat the crankshaft, ensuring proper alignment with the block dowels. Torque the main caps to the specifications listed in the Scat installation manual, and re‑check clearances after assembly.

What warranty does Scat provide for this crankshaft?

Scat offers a limited warranty that covers any manufacturing defects for a period of one year from the date of purchase. The warranty does not cover damage caused by improper installation, misuse, or modifications that deviate from the original design specifications. For warranty claims, retain the original packaging and purchase receipt.

How does the machined finish improve performance?

The machined finish creates a smoother surface on the crankshaft journals, which reduces friction between the crankshaft and bearings. This lower friction translates to less heat generation, improved efficiency, and a longer service life for both the crankshaft and bearing components. Additionally, the finish helps maintain oil film integrity, which is critical for high‑rpm operation.

Can this crankshaft be used in a racing application?

Yes, the 4-350-3480-5700 crankshaft is well‑suited for racing environments. Its lightweight construction, combined with the longer stroke, provides a favorable power‑to‑weight ratio and increased torque, both of which are advantageous on the track. However, racers should ensure that all supporting components, such as pistons, rods, and bearings, are also rated for high‑performance use to fully exploit the crankshaft’s capabilities.
