Review ENGINETECH Engine Crankshaft Kit Chevrolet Bel fits MALIBU 1965–1969

The **Enginetech 122700 Engine Crankshaft Kit** is a meticulously engineered, high-performance upgrade designed specifically for the **1965 1967 Chevrolet Malibu** and **1965 1969 Chevrolet Bel Air**, both of which house the legendary **283 cubic inch small-block V8** (also known as the "283" or "283/327" engine family). This premium crankshaft kit is crafted to enhance durability, power output, and overall engine longevity while maintaining strict compatibility with the stock engine bay and supporting components. Enginetech, a trusted name in aftermarket performance parts, has leveraged advanced materials and precision machining to deliver a crankshaft that not only replaces the stock unit but also elevates the engine s performance characteristics. The kit includes a **forged steel crankshaft** with optimized main and rod journal sizes, ensuring reduced stress and improved load-bearing capacity under high RPM and torque conditions. Unlike mass-produced aftermarket cranks, this kit features **counterweight balancing** tailored to the 283 s specific harmonic tuning, minimizing vibration and enhancing smoothness critical for both street driving and light competition use. The crankshaft s **ground and polished journals** eliminate surface imperfections, promoting smoother bearing operation and extending the life of main and rod bearings. Additionally, the kit includes **new main and rod caps** with updated gasket surfaces, preventing oil leaks and ensuring a secure fit. Enginetech s attention to detail extends to the **crankshaft s overall length and rod journal spacing**, which are precisely matched to the original engine s specifications, guaranteeing seamless integration with the stock connecting rods and pistons. Whether you're aiming to boost horsepower through forced induction, high-performance camshafts, or aggressive tuning, this crankshaft kit provides the structural integrity needed to handle increased stress without compromising reliability. Ideal for restomod enthusiasts, drag racers, or those seeking a more robust foundation for their classic Chevy V8, the **Enginetech 122700 Crankshaft Kit** represents a smart investment in performance and longevity, ensuring your 283 engine not only runs stronger but also does so with the confidence of a professionally engineered upgrade.

### **Pros and Cons of buying a EngineTech 122700 Engine Crankshaft Kit for 1965 1967 Chevrolet Malibu and 1965 1969 Bel Air**

1. **OEM Replacement Quality** EngineTech crankshaft kits are designed to match or exceed factory specifications, ensuring proper fitment and performance. They are built to handle the stress of a high-performance engine without excessive wear.

2. **Durability and Strength** The crankshaft is a critical component, and a high-quality aftermarket kit like this one is forged from premium materials, often stronger than stock parts. This reduces the risk of catastrophic failure, especially in high-RPM or modified engines.

3. **Balanced and Precision-Machined** EngineTech crankshafts undergo rigorous balancing and machining processes to ensure smooth operation, reducing vibration and improving engine longevity.

4. **Compatibility with Modifications** If you plan to build a high-performance engine (e.g., forced induction, big blocks, or aggressive camshafts), a reinforced crankshaft is essential to prevent bending or fatigue failure.

5. **Warranty and Support** Reputable manufacturers like EngineTech typically offer warranties (often 1 2 years) and customer support, providing peace of mind in case of defects.

6. **Cost-Effective Alternative to OEM** While not always cheaper than a brand-new OEM crankshaft, aftermarket kits often provide better value, especially if the original crankshaft is damaged or worn.

7. **Improved Performance Potential** A stronger crankshaft can support higher horsepower and torque, making it a smart upgrade for those pushing their engine beyond stock limits.

---

1. **Higher Upfront Cost** Compared to a used or salvaged crankshaft, a new EngineTech kit is more expensive, though the long-term benefits may justify the investment.

2. **Installation Complexity** Replacing a crankshaft requires disassembling the engine, removing the main bearings, and carefully aligning the new part. If not done correctly, it can lead to further damage or poor performance.

3. **Potential for Overkill** If your engine is running stock or lightly modified, a high-end crankshaft may be unnecessary unless you plan future upgrades. In such cases, a refurbished OEM crankshaft could be a more budget-friendly option.

4. **Compatibility Concerns** While EngineTech kits are designed for your specific application, double-checking dimensions (stroke, journal sizes, etc.) is crucial to avoid fitment issues.

5. **Maintenance Requirements** A stronger crankshaft doesn t eliminate the need for proper oil changes, bearing maintenance, and regular inspections. Neglecting these can still lead to premature failure.

6. **Limited Availability of Parts** If something goes wrong post-installation, sourcing replacement parts or finding a specialist for repairs may be difficult compared to more common OEM components.

The **EngineTech 122700 crankshaft kit** is a **strong, reliable upgrade** for a 1965 1967 Malibu or 1965 1969 Bel Air, particularly if you re planning performance modifications or want to replace a worn or damaged original part. Its **forged construction, precision machining, and compatibility with high-stress applications** make it a smart long-term investment. However, the **higher cost and installation complexity** mean it s best suited for those who are either **building a serious performance engine or replacing a failed crankshaft**.

If your engine is **stock or lightly modified**, a **refurbished OEM crankshaft** or a **budget aftermarket option** might be sufficient. But if you re **serious about power, reliability, and future-proofing your engine**, the EngineTech kit is an excellent choice.

- You re modifying your engine for forced induction, big blocks, or aggressive camshafts.

- Your current crankshaft is cracked, bent, or worn beyond repair.

- You want a **premium, long-lasting component** that supports high horsepower.

- You re comfortable with (or can afford) professional installation.

- Your engine is **stock or lightly modified**, and you want to save money.

- You re unsure about future power goals and prefer a more conservative upgrade.

- You can find a **high-quality used or refurbished OEM crankshaft** at a lower cost.

Ultimately, **performance builds benefit most from this kit**, while **stock or casual restorations** may not require it. Always verify fitment and consult with a trusted mechanic before purchasing.
