Get the Most Out of Your 350 Small Block: A Header Buying Guide
Why Headers Matter for Your 350 Small Block
Your Chevy 350 small block engine is a classic. It’s strong and reliable. But to make it even better, you need good headers. Headers replace your old exhaust manifolds. They help your engine breathe easier. This means more power and a better sound.
Key Features to Look For
- Tube Diameter: This is how wide the pipes are. Bigger pipes can help high-RPM power. Smaller pipes can help low-RPM torque. For most street 350s, 1 5/8 inch or 1 3/4 inch tubes are a good choice.
- Primary Tube Length: Longer tubes can help with low-end torque. Shorter tubes help with high-RPM power.
- Collector Size: This is where the tubes join together. A collector size of 2.5 inches is common and works well for many 350s.
- Flange Thickness: Thicker flanges are stronger. They are less likely to warp or leak.
- Spark Plug Clearance: Make sure the headers give you enough room to change spark plugs easily.
- Ground Clearance: Headers can hang low. You need to make sure they won’t hit the ground.
Important Materials
Headers are usually made from steel. There are a few types:
- Mild Steel: This is the most common and affordable. It can rust over time if not coated.
- 100% Stainless Steel: This is more expensive. But it’s much better at resisting rust. It lasts longer and looks great.
- Ceramic Coated: This coating helps keep heat in the exhaust. This can make the headers last longer and improve performance. It also looks cool.
Factors That Improve or Reduce Quality
What Makes Headers Great?
- Good Fitment: Headers that fit your car perfectly are easier to install. They are less likely to leak.
- Strong Welds: Well-made welds mean the headers will last.
- Quality Coating: A good coating protects against rust and heat.
What Makes Headers Less Good?
- Thin Metal: Thin metal can warp or crack.
- Poor Welds: Weak welds can break.
- Bad Fitment: Headers that don’t fit well are a nightmare to install. They might leak exhaust.
User Experience and Use Cases
People buy headers for different reasons. Some want more power. Others want a tougher sound. Many want both.
- Street Driving: For everyday driving, headers that offer good low-end torque and a nice rumble are popular.
- Racing: For drag racing or track days, headers designed for high RPM power are better.
- Show Cars: For cars that look as good as they perform, ceramic coated or polished stainless steel headers are a great choice.
Most users find that installing headers is a noticeable upgrade. The engine feels more responsive. The exhaust note is deeper and more aggressive. Installation can be tricky, so some people hire a professional.
Frequently Asked Questions About 350 Small Block Headers
Q: What are the main benefits of installing headers?
A: Headers help your engine breathe better. This can lead to more horsepower and torque. They also give your exhaust a deeper, more powerful sound.
Q: Do I need to change my exhaust system when I install headers?
A: Yes, usually. Headers are designed to connect to a specific type of exhaust pipe. You might need new pipes or an adapter.
Q: Will headers fit my specific 350 small block engine?
A: Most headers are designed for common 350 small block applications. Always check the product description to make sure they fit your car and engine year.
Q: Are stainless steel headers worth the extra cost?
A: For most people, yes. Stainless steel resists rust much better than mild steel. This means they will last longer and look better, especially in areas with a lot of rain or snow.
Q: What is “tube bending”?
A: Tube bending is how the pipes are shaped to fit your engine bay. Good bending ensures the pipes don’t kink, which would hurt performance.
Q: How important is collector size?
A: Collector size affects how well exhaust gases flow. For most street-driven 350s, a 2.5-inch collector is a good balance for power and sound.
Q: Can I install headers myself?
A: Yes, if you have some mechanical skill and the right tools. It can be a bit challenging, especially with tight engine bays. Many people choose to have a mechanic install them.
Q: Will headers affect my car’s fuel economy?
A: Sometimes. If the headers help your engine run more efficiently, you might see a slight improvement in fuel economy. But if you use the extra power, your mileage could decrease.
Q: Do I need to tune my engine after installing headers?
A: It’s a good idea. Headers change how your engine breathes. A tune-up can help your engine computer adjust to the new airflow, making sure it runs at its best.
Q: What is the difference between shorty headers and long tube headers?
A: Shorty headers are shorter and often easier to install. They usually offer a good balance of low-end torque and mid-range power. Long tube headers are longer and typically provide more power at higher RPMs.
