Review THOMPSON PISTONS Vintage Engine Standard Part White fits 1936–1939
The Thompson L651 engine, a marvel of 1937 engineering, is a testament to the advancements in automotive technology during that era. This straight-six, side-valve engine is a powerhouse, delivering reliable performance with its 3.3-liter displacement. The L651 is known for its robustness, thanks to its cast-iron block and cylinder head, which ensure durability under heavy use.
The engine features a single carburetor, which, combined with its six cylinders, provides a smooth and powerful driving experience. The engine's compression ratio is optimized for performance and fuel efficiency, with a ratio of 7.0:1. The L651 is also equipped with a conventional ignition system, ensuring reliable spark and combustion.
Transitioning to the L671 engine, we see further advancements in 1938 and 1939. The L671 shares many similarities with the L651, but it boasts an increased displacement of 3.5 liters. This larger engine capacity results in even more power and torque, making it an excellent choice for those seeking a more potent driving experience.
The L671 engine's cast-iron block and cylinder head remain, ensuring durability and reliability. The engine also retains its side-valve configuration, providing smooth operation and long engine life. The L671's compression ratio is slightly higher than the L651, at 7.25:1, further optimizing performance.
Both the L651 and L671 engines are compatible with a wide range of Thompson vehicles, making them versatile choices for enthusiasts and collectors alike. Whether you're restoring a classic Thompson car or simply looking for a reliable engine, these Thompson piston engines are sure to satisfy your needs.
Thompson L-651 (1937) and L-671 (1938-1939) engines are both six-cylinder, air-cooled radial engines designed for use in military aircraft during World War II. Here are some pros and cons of buying either engine for restoration or use in a vintage aircraft:
Thompson L-651 (1937)
Pros:1. Relatively simple design, making it easier to maintain and repair than more complex engines.
2. Widely available spare parts due to its use in various military aircraft.
3. Long service life if properly maintained.
Cons:1. Lower power output compared to more modern engines.
2. Requires more frequent maintenance due to its air-cooled design.
3. May require modifications to fit into modern aircraft due to its older design.
Thompson L-671 (1938-1939)
Pros:1. Increased power output compared to the L-651.
2. Improved reliability and durability due to design improvements.
3. Wide availability of spare parts.
Cons:1. More complex design, which can make maintenance and repair more challenging.
2. Requires more horsepower to achieve similar performance compared to modern engines.
3. May require modifications to fit into modern aircraft due to its older design.
Conclusion:Both engines offer pros and cons, and the best choice depends on your specific needs and preferences. If you are looking for a simpler, lower-powered engine that is easier to maintain and repair, the L-651 may be a better choice. On the other hand, if you need more power and are willing to put in more time and effort for maintenance and repair, the L-671 may be a better option. Ultimately, it is important to carefully consider your requirements and research the specific engine thoroughly before making a decision.
