**Pros and Cons of buying a AllStar Performance All87030 Crankshaft Key for a Chevy 2PK Engine**

The **AllStar Performance All87030 crankshaft key** is designed to fit the **Chevy 2PK (292/327 cubic inch small-block V8)** engines, particularly those with a **flat-top crankshaft** that lacks a keyway. This part is essential for proper crankshaft rotation and preventing damage during assembly or disassembly. Below are the key advantages and disadvantages of purchasing this product.

### **Pros**

1. **Precision Fit and Functionality**

- The All87030 is specifically engineered to match the **Chevy 2PK crankshaft profile**, ensuring a secure fit in the crankshaft s journal. This prevents the crank from spinning freely, which can lead to catastrophic engine damage if the flywheel or other components loosen during operation.

2. **High-Quality Materials**

- AllStar Performance products are generally made from **hardened steel or high-grade alloy**, which provides durability and resistance to wear. This ensures longevity, especially in high-performance or modified engines where stress on the crankshaft is increased.

3. **Easy Installation**

- Unlike machining a keyway into the crankshaft (which requires specialized tools and labor), this aftermarket key can be installed quickly. It fits into the existing crankshaft journal without the need for modifications, making it a convenient solution for restorers, mechanics, and DIY enthusiasts.

4. **Cost-Effective Alternative to Crankshaft Machining**

- Machining a keyway into a crankshaft can be expensive, often costing **$100 $300 ** depending on the shop. The All87030 key is typically priced significantly lower (often **$20 $50**), making it a budget-friendly option for those who don t want to modify their crankshaft permanently.

5. **Compatibility with Aftermarket and Stock Applications**

- This key works well in both **stock and modified Chevy 2PK engines**, including those with **performance camshafts, high-lift cams, or aggressive engine builds** where crankshaft rotation control is critical.

6. **Reduces Risk of Engine Damage**

- Without a crankshaft key, the flywheel or flexplate can spin freely on the crank, leading to **seized main bearings, damaged crankshaft journals, or even a blown engine** if the flywheel detaches. The All87030 eliminates this risk by providing a secure locking mechanism.

7. **Backed by a Reputable Brand**

- AllStar Performance is a well-known manufacturer in the **Chevy small-block and big-block aftermarket**, with a history of producing reliable engine components. Their products are widely trusted by mechanics and enthusiasts.

### **Cons**

1. **Not a Permanent Solution for All Crankshafts**

- While the All87030 fits **flat-top 2PK cranks**, it **will not work on cranks with existing keyways** (such as those from later Chevy engines or aftermarket cranks with pre-machined slots). If the crank already has a keyway, this part is unnecessary.

2. **Requires Proper Installation Technique**

- Improper installation (e.g., incorrect orientation, insufficient torque, or misalignment) can lead to **premature wear or failure**. The key must be **snugly fitted and properly seated** in the crankshaft journal to function correctly. Some users may need to **file or deburr** the crank journal slightly to ensure a perfect fit.

3. **Limited Use in Certain Engine Builds**

- In **highly modified engines** (e.g., those with **superchargers, turbochargers, or extreme horsepower levels**), some builders prefer **machined keyways** for added strength and reliability. While the All87030 works well in most cases, purists or high-performance builders might opt for a more permanent solution.

4. **Potential for Wear Over Time**

- While high-quality, **any aftermarket key is subject to wear**, especially in high-stress applications. If the engine sees **extreme torque or frequent disassembly**, the key may eventually wear out and require replacement.

5. **Not Universal Across All Chevy Small-Blocks**

- This specific key (**All87030**) is **only for the 2PK (292/327) flat-top crank**. Chevy engines with **round-top cranks (e.g., 350, 400, 454, or later models)** require different keys. Buyers must ensure they have the correct crankshaft type before purchasing.

6. **May Not Be Needed in All Cases**

- Some **stock Chevy 2PK engines** (especially those with **stock flywheels and mild applications**) may not require a crankshaft key if the flywheel is securely bolted and the engine is not subjected to extreme stress. However, in **performance builds, drag racing, or high-torque applications**, the key is strongly recommended.

---

### **Conclusion and Recommendation**

The **AllStar Performance All87030 crankshaft key** is a **practical, cost-effective, and reliable solution** for Chevy 2PK engines that lack a keyway. It provides **critical protection against flywheel spin and crankshaft damage**, making it an essential component for **restorations, performance builds, and high-stress applications**.

#### **Who Should Buy It?**

- **Restoremoders** rebuilding a **2PK Chevy engine** (292/327) with a flat-top crank.

- **Performance enthusiasts** modifying their engine with **high-lift cams, forced induction, or aggressive power levels**.

- **Mechanics and DIYers** who want to avoid the expense and complexity of machining a keyway.

- **Drag racers and street rods** where engine reliability is paramount.

#### **Who Might Not Need It?**

- Owners of **Chevy engines with existing keyways** (e.g., 350, 400, or later models).

- Those building **stock or mildly modified engines** with **stock flywheels and low torque**.

- Builders who prefer **permanent crankshaft modifications** (e.g., machined keyways) for maximum strength.

#### **Final Recommendation**

**If you have a Chevy 2PK (292/327) flat-top crankshaft and are building a performance engine, installing the All87030 crankshaft key is a smart investment.** It is **far cheaper and easier** than machining a keyway, and it **significantly reduces the risk of catastrophic engine failure** from flywheel spin. For most **restoration, street, or racing applications**, this key is **highly recommended**.

If you are unsure whether your crankshaft needs it, **verify the crank type (flat-top vs. round-top)** and consult with a **trusted mechanic** before purchasing. However, for the **average 2PK performance build**, the All87030 is a **must-have safety component**.
