Power fan headers are connectors on a computer motherboard designed to supply power to additional cooling fans. They allow users to connect and control fan speed, ensuring optimal airflow and temperature management within the system. These headers can typically support various types of fans, including PWM (Pulse Width Modulation) and DC fans, enabling precise fan control based on thermal demands. Properly utilizing power fan headers helps maintain system stability and longevity.
They do give more horse power
yes
They help the engine "breath" better.
Headers help to maximize exhaust flow which allows your engine to run more smoothly and use less power per stroke. Because of this headers can improve fuel economy but the change is very small.
If your looking for raw open power than no. But you can't drive a vehicle on the roads with open headers. So it's mainly off-road trucks or high hp mud trucks that run open headers.
intake manifold and headers or replace with 350
Installing a after-market exhaust will Increase MPG and low-end and high-end power outputs. Also with addition to headers will come Increased loudness and Horsepower and low-end torque.
The only company to sell headers made for this car is a company called Ford Power Train. Very high quality headers that are built very well. Just google the name and you will find there site.
I added: Hypertech chip, K&N air filter, headers with dual exhaust. The best improvement came from the headers.
A fan on the engine blows air through hoses and into the heater box that is wrapped around the exhaust headers. The heated air from the exhaust headers in the heater box is then blown into the cabin.
For a 1972 Chevy Nova with a small block 350 engine, power steering, power brakes, and factory air conditioning, you would typically need shorty headers or specific mid-length headers designed for clearance. Brands like Hedman, Hooker, and Doug’s offer headers that accommodate these features without interfering with the AC or steering components. It's essential to ensure that the headers are compatible with the exhaust system you plan to use and check for any potential fitment issues specific to your setup. Always verify the specific model and year compatibility when purchasing headers.
