Finding the perfect distributor for your 350 Chevy can feel overwhelming with so many options on the market. This guide will break down the key factors to consider, helping you choose the right distributor to optimize your engine's performance and reliability. Whether you're rebuilding a classic muscle car or building a high-performance street machine, selecting the appropriate distributor is crucial.
Understanding Distributor Types for Your 350 Chevy
Before diving into specific models, it's vital to understand the different types of distributors available. Your choice will heavily depend on your engine's specifications and your performance goals.
1. HEI (High Energy Ignition) Distributors:
- Pros: HEI distributors are known for their superior spark energy, improved reliability, and ease of installation compared to older systems. They generally require less maintenance and offer better performance. Many consider them the best option for street and mild performance applications.
- Cons: While highly reliable, some HEI units can be more expensive than other options. Finding the exact right curve for your specific needs may require some experimentation.
2. Points-Type Distributors:
- Pros: These classic distributors are relatively inexpensive and readily available. They are a good choice for budget-conscious builds or restoration projects aiming for originality.
- Cons: Points distributors require more maintenance, including regular point gap adjustments and condenser replacements. Their spark energy is significantly lower than HEI systems, potentially leading to performance limitations.
3. Electronic Ignition Conversion Kits:
- Pros: These kits offer a cost-effective way to upgrade a points distributor to electronic ignition, improving reliability and performance without a complete distributor replacement.
- Cons: They require some mechanical aptitude for installation and may not offer the same level of performance as a dedicated HEI distributor.
Key Factors to Consider When Choosing Your 350 Chevy Distributor
The optimal distributor for your 350 Chevy depends on several crucial factors:
1. Engine Modifications:
- Stock Engine: For a stock or mildly modified 350 Chevy, a standard HEI distributor will likely suffice.
- High-Performance Engine: High-performance engines may benefit from a performance-tuned HEI distributor with an adjustable mechanical advance and vacuum advance. Consider distributors with billet components for increased durability at higher RPMs.
- Cam Profile: The camshaft's profile significantly affects ignition timing requirements. Aggressive camshafts often necessitate a distributor with adjustable timing curves.
2. Budget:
HEI distributors range in price, from budget-friendly options to high-end performance units. Points distributors offer a lower initial cost, but long-term maintenance expenses should be factored in.
3. Desired Performance Level:
For street-driven vehicles, a reliable HEI distributor provides excellent performance and longevity. Race cars or heavily modified engines might require a fully adjustable distributor for precise ignition timing control.
4. Installation:
While HEI distributors are generally easier to install, some knowledge of basic engine mechanics is helpful for any type of distributor installation.
