Do you own a Ford 351M, and are you interested in getting more power from this powerful engine? It is not just about getting more power from the car. It is also about better throttle response, the link between the ECM and injectors, fuel trims, and that famous roar of a Ford! This article covers the best headers for 351M engines. There are helpful tips for Ford enthusiasts.
Though born in the mid-1970s, the Ford 351M was able to find a place in many Ford-based trucks and Jeeps. The intake ports opened downward. Unlike the FE, Ford designed it to replace older engines. They focused on emissions and easier manufacturing. With many similarities to the 400-cubic-inch V8, the 351M had a taller deck and could be used with many other versions of the Ford small-block V8.
Long tube ford headers are meant for high-rpm horsepower, which is suitable for track performance and high-performance street car applications.
These little headers allow for easier installation and more clearance from the ground and definitely provide good gains for one’s regular use of the vehicle.
Over 4000K are produced with a ceramic coating on the headers that offers lower under-hood temperatures, as well as durability.
Headers are also almost as durable and are often made from stainless steel for an enhanced appearance through polishing.
That is why the thinnest uncoated steel headers are the least expensive, though they corrode easily.
Street headers have fitment and clearance on their priority list as they make sure complex compliances (for instance, the starter, or steering) stays uncomplicated.
Racing headers, mainly, are not as close a fit as stock headers relative to the ease of installation so that they can boast of as much flow and horsepower.
Chassis and clearance: Double-check compatibility for your vehicle’s specific frame and body style (F-100 vs. Bronco, for example).
Automatic and manual transmissions (their headers) may need different header variants for clearance of linkage depending on their type.
The coated and stainless forms add to the product’s durability and have better performance under high-heat treatment.
Search for thick flanges and inspect the seams that the TIG/MIG method has welded.
Choose headers that match changes in camshafts, intakes, or carburetors. If you've made changes, use larger primaries. It helps increase airflow.
Pollution control: Some states specify the use of EGR or catalytic converters; not all headers are legal for use in each state. Always verify before purchasing.
Beginner tips often recommend using hands to fix headers. Most models are easy to install if you’re patient and have the right tools. However, if one does not have the time or energy to do exhaust work or has busted knuckles, then a shop may be the best option.
The following clearances may be an issue: Starter – change its location or be ready to move it. Starter – it may be necessary to change or remove the dipstick tube. Transmission – change the position of the lines.
Old hardware: Expect rusty bolts and stubborn studs on the original exhaust manifolds.
Employment of a high-quality timing belt is recommended, as well as the use of bolt torque in steps.
One could perform some bolt-on updates on the 7.5L 351M Cleveland motor and say that headers are just a way of gaining more horsepower. It’s about reviving your dull Ford. You can bring it back to life with new energy. Enjoy every throttle blip and make your garage time even better. If you enjoy long cruises, off-road driving, or love the V8 engine's roar, headers are a must-have.
