I’m currently working on my 400 cubic inch small-block Chevrolet (SBC) engine build and I’m at a bit of a crossroads when it comes to choosing the right cylinder heads. I want to maximize performance and power while also being mindful of budget constraints.
What I’m Looking For
I’d love to hear from those who have experience with SBC builds:
Head Types: What are the best types of heads you’ve used or recommend for this engine? Are there specific brands or models known for boosting performance?
Technical Specs: I’d appreciate details on port sizes, lift measurements, and any other specific features that set certain heads apart.
Compatibility: Are there any heads that are known to integrate well with specific setups? I want to avoid any compatibility issues down the road.
Performance Goals
My goal is to enhance efficiency and get the most power out of my setup. If you’ve done something similar, I’d love to hear about your experiences and what worked well for you.
Other Considerations
Price: What should I expect to invest? I know some options can get pretty pricey, so if you’ve found a good balance between cost and performance, please share!
Personal Experiences: Any personal stories or lessons learned during your head selection process would be incredibly helpful.
Looking forward to your insights! Thanks in advance for your help.
If you’re looking for the best heads for a 400 SBC, I’d recommend checking out the World Products heads. They have great flow characteristics and can really boost your performance.
I agree! The World heads are solid, but don’t overlook the Edelbrock Performer RPM heads if you’re going for a street-friendly build. They have excellent torque and flow.
Factory heads like those from the late 70s can also be a decent option. They have more compression for better efficiency, especially if you’re on a budget.
Performance heads will really change how your 400 SBC performs, especially with the right camshaft. Think about your setup and how you want it to behave.
Good choice! Dart heads are fantastic for performance builds, just make sure to match them with your entire engine setup, including the intake and exhaust.
Airflow is definitely crucial! A well-designed head can significantly enhance performance by reducing restrictions, but it depends on what you’re aiming for – daily driving or racing.
