Review CALLIES Stealth Crankshaft Sbc 3.5 Stroke

The **Callies Sag116 Stealth Crankshaft (3.5)** is a high-performance, precision-engineered component designed to elevate the power delivery, durability, and overall driving experience of modern high-revving engines, particularly those in turbocharged or naturally aspirated performance applications. Crafted from a proprietary **4140 chromium-molybdenum alloy steel**, this crankshaft is forged to exacting standards, ensuring exceptional strength, fatigue resistance, and the ability to withstand extreme stress under high RPM conditions. The **3.5-inch stroke** provides a substantial boost in displacement, making it an ideal choice for enthusiasts looking to maximize torque and horsepower without sacrificing reliability. The **stealth design** refers to its streamlined, low-profile counterweights, which not only reduce rotational mass for improved revving capability but also minimize vibration and harshness, resulting in a smoother, more refined power delivery. This crankshaft features **fully machined journals and counterweights**, eliminating the need for welding or casting, which enhances structural integrity and reduces the risk of failure under heavy loads. The **polished finish** on the main and rod journals ensures optimal oil retention and reduces friction, contributing to improved efficiency and longevity. Whether integrated into a **turbocharged engine** for aggressive power gains or a **naturally aspirated high-RPM setup**, the Sag116 Stealth crankshaft delivers a perfect balance of strength, responsiveness, and precision engineering. Built to meet the demands of serious performance builds, this component is a testament to Callies commitment to innovation and craftsmanship, offering a reliable foundation for those pushing the limits of their engines.

### **Pros and Cons of Buying a Callies Sag116 Stealth Crankshaft (3.5")**

1. **Performance Gains** The Sag116 crankshaft is designed for increased power output, particularly in high-RPM applications. The 3.5" stroke is optimized for torque and efficiency, making it suitable for forced induction builds (turbo/supercharged) or high-revving engines.

2. **Balanced Weight Distribution** Callies cranks are known for precision machining and balanced weight, which reduces vibration and improves drivability. This can lead to smoother operation and longer engine life.

3. **Durability and Strength** The Sag116 is forged from high-quality steel, offering superior strength compared to stock cranks. It can handle higher stress levels, making it ideal for aggressive builds.

4. **Compatibility with Aftermarket Parts** The 3.5" stroke is a popular choice for performance builds, meaning there are plenty of supporting parts (rods, pistons, oil pumps, etc.) available to pair with it.

5. **Reputation of Callies** Callies is a well-respected brand in the performance crankshaft market, known for reliability and precision engineering. Their cranks are often used in professional racing and high-performance applications.

6. **Improved Reliability** A properly matched crankshaft can reduce the risk of catastrophic failure, especially in engines running at higher stress levels.

7. **Customization Options** Callies offers various crankshaft designs (e.g., different rod journal sizes, counterweight configurations) to fine-tune performance based on engine specs.

1. **Cost** High-quality performance cranks like the Sag116 are significantly more expensive than stock cranks. The price can range from **$1,500 to $3,000 **, depending on additional features (e.g., nitrided finish, custom machining).

2. **Installation Complexity** Replacing a crankshaft requires disassembling the entire engine, which can be labor-intensive and costly if done professionally. DIY installation is risky and may void warranties.

3. **Engine Modifications Required** To fully realize the benefits of a Sag116, other components (rods, pistons, oil pump, timing chain/gear) may need upgrading. This adds to the overall cost and complexity.

4. **Potential for Overbuilding** If the rest of the engine (block, head, fueling, etc.) isn t properly matched, the crankshaft alone won t deliver optimal performance. An unbalanced build can lead to reliability issues.

5. **Warranty and Return Risks** Since cranks are custom-fitted, most manufacturers (including Callies) offer limited warranties. If installation errors occur, repairs can be costly.

6. **Not Always Necessary for Stock or Mild Builds** If you re running a naturally aspirated engine with stock components, the gains from a Sag116 may not justify the expense. It s best suited for forced induction or high-performance applications.

7. **Lead Time** Custom cranks often have longer lead times due to machining and quality control processes.

### **Conclusion**

The **Callies Sag116 Stealth Crankshaft (3.5")** is an excellent choice for **high-performance builds**, particularly those involving **forced induction, high-RPM applications, or aggressive power gains**. Its precision engineering, durability, and compatibility with aftermarket parts make it a strong investment for serious enthusiasts and racers. However, the **high cost, installation complexity, and need for supporting modifications** mean it s not a necessary upgrade for stock or mildly modified engines.

If you re planning a **turbocharged, supercharged, or high-revving project**, the Sag116 is a **solid long-term investment** that will enhance reliability and power. For **stock or mild builds**, a stock or slightly upgraded crankshaft may be sufficient.

### **Recommendation**

- **Buy it if:** You re running a **forced induction setup, high-RPM engine, or a build requiring significant power gains**. Ensure your engine block, rods, pistons, and oil pump are properly matched.

- **Skip it if:** You re on a budget, running a **stock or naturally aspirated engine**, or haven t budgeted for additional supporting modifications.

- **Consider alternatives if:** You need a more budget-friendly option, such as a **stock crank with upgraded rods** or a **less aggressive performance crank** (e.g., 3.25" stroke).

For the best results, consult with a **performance engine builder** to ensure proper matching of all components.
