Review CHEVROLET PERFORMANCE 383 Connecting Rod 383ci Engines Third Design Pm

The **Chevrolet Performance Part Number 19355718** is a meticulously engineered **third-design connecting rod** specifically tailored for **383 cubic inch (CI) small-block Chevrolet engines**, representing a critical component in the powertrain s structural integrity and performance. This rod is crafted from **high-strength forged 4340 chrome-molybdenum alloy steel**, a material renowned for its exceptional fatigue resistance, durability, and ability to withstand the extreme stresses of high-revving, high-horsepower applications. The design adheres to Chevrolet s **third-generation rod pattern**, which features a **1.625-inch small end diameter** and a **1.9375-inch large end width**, ensuring precise fitment within the engine s crankshaft journals and cap interfaces. The rod s **split-pin style** construction incorporates **hardened steel split pins** for secure retention of the rod cap, while the **full-floating design** eliminates binding, allowing for optimal piston movement and minimizing friction. The **polished rod ends** and **precision-machined surfaces** enhance oil flow and reduce wear, making this rod ideal for both **street and strip** applications, including forced induction builds, high-lift cam installations, and aggressive tuning scenarios. Whether integrated into a **restomod project** seeking OEM accuracy or a **high-performance engine** pushing beyond stock limits, this rod delivers the strength, reliability, and precision required to handle the demands of modern Chevrolet small-block engines. Built to Chevrolet s exacting standards, it serves as a foundational element for engines aiming to balance power output with long-term durability.

### **Pros and Cons of Buying a Chevrolet Performance 19355718 383ci Engine (Third Design, PM Version)**

1. **Proven Performance** The 383ci small-block Chevrolet engine, particularly the third design (1967 1972), is one of the most reliable and tunable engines ever made. The PM (Performance Model) version features a forged crankshaft, stamped steel rods, and a more robust block, making it ideal for high-performance applications.

2. **Widely Available Parts** Due to its popularity, replacement parts, gaskets, seals, and performance upgrades are readily available. Aftermarket support includes everything from basic maintenance items to high-performance components like headers, camshafts, and fuel systems.

- **Big-Bore Kits** Allows for displacement increases (e.g., 400ci, 427ci) while maintaining the same basic architecture.

- **High-Performance Camshafts** Improves throttle response and power output.

- **Forced Induction** Naturally aspirated or turbocharged builds are common and effective.

- **Fuel Injection** LPI (Liquid Port Injection) or EFI (Electronic Fuel Injection) can be easily retrofitted.

4. **Durability** The PM version, in particular, is built tougher than standard 383s, with a forged crankshaft and stronger connecting rods, making it suitable for high-RPM applications and forced induction.

5. **Cost-Effective for Builds** Compared to modern engines, the 383ci remains relatively affordable to purchase, rebuild, and modify. A well-maintained PM 383 can be had for a few thousand dollars, making it a great choice for budget-conscious builders.

6. **Classic Muscle Car Appeal** If you're restoring or building a classic American muscle car (e.g., Chevelle, Camaro, Nova), the 383ci PM engine is a natural fit and adds to the car s vintage appeal.

7. **Long-Term Reliability** With proper maintenance (oil changes, valve adjustments, rod bearing checks), a 383ci engine can last well over 100,000 miles, especially in street or light drag applications.

---

- **Rod Bearing Wear** Even PM versions can develop bearing wear over time, especially if the engine was run with poor lubrication.

- **Camshaft and Lifters** Older engines may have worn cams or lifters, leading to rough idle or valve train noise.

- **Head Gasket Failure** Common in high-mileage engines, often requiring a full head replacement or resurfacing.

- **Rod Bolts** Some older engines use soft rod bolts, which can stretch or fail under high stress. Replacing them with ARP or similar hardware is recommended.

2. **Fuel System Limitations** The stock carburetion (e.g., Holley 4150, Carter AFB) is not optimized for modern fuel standards or high-performance builds. Retrofitting a fuel injection system or upgrading the carburetor is often necessary for reliable operation.

- **Evaporative Emissions Control (EVAP) System** Modern cars require a functional EVAP system, which may not be stock on older builds.

- **OBD-II Requirements** Some states require OBD-II compliance, which can be tricky with a vintage engine unless you install an aftermarket solution like a standalone ECU or tuner.

- **Vibration** The small-block Chevy s design can produce noticeable vibration at high RPM, especially without a harmonic balancer or vibration dampeners.

- **Loudness** A high-performance 383ci will be noticeably louder than a modern engine, which may not be ideal for daily driving in noise-restricted areas.

5. **Fuel Economy** The 383ci, even in its most efficient form, will not match the fuel economy of a modern engine. Expect around **12 16 MPG** in a naturally aspirated build, depending on drivetrain and driving style.

- **Proper Balancing** Forced induction or high-RPM applications demand a balanced crankshaft and rotating assembly.

- **Cooling System Upgrades** Stock cooling may not be sufficient for aggressive builds, requiring larger radiators, upgraded water pumps, or electric fans.

- **Exhaust and Intake Restrictions** Stock exhaust manifolds and intake runners can limit airflow; aftermarket headers and intakes are often necessary.

7. **Resale Value** While a well-built 383ci engine retains value among enthusiasts, a complete car with one may not hold its value as well as a modern muscle car, especially if it requires extensive maintenance.

The **Chevrolet Performance 19355718 383ci PM engine** is an excellent choice for enthusiasts looking to build or restore a classic American muscle car, especially those prioritizing performance, reliability, and modifiability. Its robust construction, widespread parts availability, and proven track record make it a favorite in street and drag applications. However, potential buyers should be prepared for the challenges of maintaining a vintage engine, including potential wear issues, fuel system upgrades, and emissions compliance.

If you are willing to invest time and effort into a rebuild or restoration, the 383ci PM offers **unmatched value for performance per dollar**. For those seeking a plug-and-play solution or a modern driving experience, a contemporary engine may be more practical.

---

- You are building or restoring a classic muscle car and want a powerful, reliable engine with endless upgrade potential.

- You are comfortable with mechanical work and willing to invest in a rebuild or restoration.

- You prioritize performance over fuel efficiency and modern refinements.

- You plan to use the engine in a street or light drag application where reliability and modifiability are key.

- You want a turnkey solution with minimal maintenance.

- You need excellent fuel economy or modern driving comforts.

- You are not interested in working on a vintage engine and prefer a contemporary powerplant.

- Emissions compliance or noise restrictions are major concerns in your area.

For most enthusiasts, the **383ci PM is a fantastic choice** it s a piece of automotive history that delivers real-world performance while offering endless customization options. Just be prepared to put in the work to keep it running smoothly.
