### **Pros and Cons of Buying a 1937-1939 Chevrolet 216 Stovebolt Inline Engine (GM Crankshaft #838877, NOS)**

#### **Pros**

1. **Classic and Iconic Design** The Chevrolet 216 Stovebolt engine is a legendary piece of automotive history, especially from the late 1930s. It represents a bygone era of American engineering and craftsmanship, making it highly desirable for collectors and enthusiasts.

2. **Strong Community and Support** The Stovebolt engine has a dedicated following, with numerous forums, clubs (such as the **Stovebolt Specialty Club**), and aftermarket parts suppliers. This means you ll find help, modifications, and restoration advice easily.

3. **Modification Potential** While stock, the 216 is a solid base for performance upgrades. Aftermarket companies offer performance camshafts, cylinder heads, and intake manifolds that can significantly improve power. Some owners have pushed these engines into the **150-200 HP range** with relatively simple modifications.

4. **Simplicity and Durability** The Stovebolt is a straightforward inline-six with a side-valve design, meaning it s easier to work on than modern overhead-valve engines. Many parts are still available, and the engine is known for its reliability when properly maintained.

5. **Restoration Value** A well-preserved or restored 1937-1939 Stovebolt can appreciate in value, especially if it s in a rare or historically significant vehicle. Some examples, particularly those in show condition, sell for **$5,000 $20,000 ** depending on condition and provenance.

6. **Unique Driving Experience** The Stovebolt s side-valve design and heavy flywheel give it a **distinctive, smooth but sluggish** throttle response compared to modern engines. Many owners appreciate the **vintage feel** and the challenge of driving a car with such an old powertrain.

7. **Availability of NOS (New Old Stock) Parts** Since the 1930s, many original components (including the GM crankshaft #838877) have been preserved in warehouses. This means you can often find **original or high-quality reproduction parts** without needing extensive custom fabrication.

8. **Great for Restoration Projects** If you re restoring a classic Chevrolet (like a **1937-1939 Master, Fleetline, or Suburban**), a Stovebolt engine is a logical choice. The engine fits well with the era s styling and mechanical simplicity.

#### **Cons**

1. **Low Power Output** The stock 216 Stovebolt produces only ** 60-70 HP**, which is **woefully inadequate** for modern driving standards. Even with upgrades, it will never match the power of a modern engine. This makes it impractical for daily driving unless you re okay with slow acceleration and high RPM cruising.

2. **Poor Fuel Economy** Due to its inefficient side-valve design and lack of modern fuel injection, the Stovebolt consumes fuel at a **very poor rate** likely **10-15 MPG** in a stock condition. This can be expensive to run, especially if you modify it for better performance.

3. **High Maintenance Requirements** Side-valve engines like the Stovebolt require **more frequent valve adjustments** (typically every **5,000 10,000 miles**) compared to modern overhead-valve designs. The lack of hydraulic lifters means manual adjustment is necessary to prevent valve float and engine damage.

4. **Limited Modern Compatibility** While the Stovebolt fits in many classic Chevrolets, some modern modifications (such as **high-performance fuel systems, turbocharging, or direct injection**) are difficult or impractical due to the engine s age and design constraints.

5. **Rust and Wear Issues** Many original Stovebolt engines (especially from the late 1930s) suffer from **rust, worn bearings, and seized components** if not properly stored. A NOS crankshaft (#838877) is a good sign, but the rest of the engine may still need **extensive rebuilding**.

- A **new cylinder block** (if cracked or worn)

- **Reconditioned or new pistons, rods, and bearings**

- **Custom machining** (if the crankshaft or camshaft is worn)

- **Modern fuel and ignition upgrades** (if you want reliable performance)

7. **Driving Limitations** The engine s **heavy flywheel and low RPM torque** make it feel **slow and sluggish** compared to modern engines. Acceleration will be **noticeably weaker**, and passing on highways will be difficult.

8. **Insurance and Registration Challenges** Some insurance companies may **charge high premiums** for classic cars with low-power engines, and registration fees for high-value restorations can be steep.
