Made 404 to the wheels with a JLT intake and tune only. Our friends at Summit Racing sell short and long-tube headers for your ’67 Fairlane. I would like to see all your short & long tube headers offered for my 67 Ford Fairlane with FE 427 engine with 2″ and larger primaries. Trust me there is a big performance difference though they may look alike. The S197 airboxes flow enough air to easily support I think close to 500hp without restricting airflow. If any of the recommended tuners are in your area, use them. Any assistance on header choice would be greatly appreciated. For that reason, most header manufacturers recommend modest pipe diameters for street applications—1 ½-inch to 1 5/8-inch diameter primaries for a small block engine, for example. With stock exhaust manifold? Shorty headers also typically work with the remaining stock exhaust components without modification (full-length headers require some modifications), so installation is often a quick, clean process. We’ll keep our focus on the most common street performance designs: full-length, shorty, and mid-length. The stock manifolds are restrictive, but a set of mandrel-bent aftermarket headers will allow the exhaust gas to move freely from the engine, reducing power-robbing backpressure in the process and allowing your exhaust system to expel gases even more efficiently. Maybe not What part of the country do you live in? If it's a 3V, mid-length shorties such as the JBA yield a useful TQ gain over the stock manifolds especially at lower rpm on a N/A set up. Shorty headers consist of four short primaries that dump into one short collector pipe. As we mentioned earlier, full-length headers typically use a 4-1 design to empty the primaries into the collector pipe. No matter which style you choose, you can take full advantage of your new headers by scrapping the rest of your restrictive stock exhaust, including the mufflers—find out how to choose the right muffler now. However, as we will see, the quality of manifold exhaust flow rate varies from vehicle to vehicle. Having power gains is always good, but it is even better when those gains occur through the entire rev range. Headers are installed because they boost the rate of exhaust flow out of your engine compared to OEM stock exhaust manifolds, which are typically designed to take up as little space as possible. In most cases, these four primary tubes empty into one collector pipe and form a “4-1” design. You get a significant performance increase compared to stock exhaust manifolds, at an off-the-shelf price. Stock headers are fine for N/A mild bolt ons. This is a new motor listed in the GM performance catalog. (You must log in or sign up to reply here. I bought this motor with EFI and complete serpentine belt system to include AC pump, alternator, and power steering pump. They provide longer primaries than the stock manifold to help produce more of that coveted low- and mid-range torque and power. This is a 4spd car with a scatter sheild & large oil pan.. Hey Jim. Of course, the first exhaust components to handle spent exhaust gases from your engine are the exhaust manifolds or headers. I need help with which headers to buy that will fit the car. You may need to download version 2.0 now from the Chrome Web Store. Here’s a link to to the 13 parts that fit a ’67 Fairlane with the 427 engine. These finishes are a more affordable alternative to coated headers, but don’t provide the performance or durability benefits. Some will say that with email tunes available it doesn't matter. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. I think it does. Put the manifolds back on and a new stainless system with the transverse muffler from a reputable fabricator, it sounds good, not deafening like before and the car is cooler in the summertime too. Plus, Sanderson headers provide excellent clearance around spark plugs, starter and chassis components, as well as ground clearance for lowered vehicles. In that case save your money for the Procharger and screw long tubes. Spend the money elsewhere or go long tubes if they're legal in your state. This keeps heat inside the primaries and helps keep ambient temperatures low in the engine compartment. While we are talking about aftermarket 'performance' parts that do absolutely nothing for performance but tend to lighten your wallet, let's not forget about aftermarket CAI kits. If it's a Coyote 5.0, any aftermarket shorty will be a waste of money even on a forced induction set up.

There are many factors that go into choosing the right pipe diameter—engine size, horsepower, intended use of the vehicle, and more—but one common mistake that many hot rodders make is to assume bigger is better. The more power you make the more headers help you. Mid-length headers offer some of the benefits of full-length and shorty headers. Discussion in 'Mustang Chit Chat' started by Jhol, May 28, 2020. ). That means cooler, denser intake charges and increased horsepower. With help from a childhood friend that is a fantastic mechanic we will bring this 49 yr old machine into the 21st century. A good set of headers will actually build up enough exhaust flow velocity to create energy pulses that pull or scavenge spent gases from the engine. Cloudflare Ray ID: 5ec97a8e5b649754 Shorty headers will help power over stock manifolds.

Long tube headers make more top end power than shortys but sacrifice low and mid range. The advantage of choosing a standard steel header is simple: cost. Your email address will not be published. Although smaller-diameter primaries will flow less volume than bigger primaries, a smaller diameter pipe actually creates faster exhaust flow velocity with just enough resistance to foster good low- and midrange torque. Most aftermarket headers are made from steel or stainless steel. So what makes a good header for your application? These secondary pipes allow the exhaust gases to maintain a higher velocity for a longer period of time as they gradually merge into the collector. No dyno's or tuners in my immediate area.

The '11+ GT already has shorty headers from the factory so any aftermarket shorty header isn't likely to be much of an improvement. A Corvette with stock manifolds can add ported manifolds, shorty headers, mid-length headers, and full-length (aka long-tube) headers.
