![]() The 427 SOHC obviously uses a unique intake that does not at all resemble any other FE part. The exceptions are the same ones noted in Chapter 6. Some of the commentary found in this chapter is based at least in part on Jay’s efforts.Īs a lead in to the manifold discussion, it is important to note that every intake does not physically fit onto every FE engine. The dyno testing does a great job of delivering comparative wideopen- throttle (WOT) performance but does not quantify part-throttle behavior. His efforts have brought some unexpected “winners” to light, and quashed a few urban legends as well. Jay Brown, a well-known FE enthusiast and racer, has done exhaustive dyno testing on literally dozens of FE intake manifolds. If you are interested in historical research (the FE has a vast amount of outstanding racing history), there are other publications that better serve those needs. Rather than trying to detail every available original part number or aftermarket option, or selecting a “winner” among the plethora of intakes available, I’ll just cover general guidelines and the most popular choices. Dualplane designs such as this are ideally suited for high-performance street use because they deliver quick throttle response, superior acceleration, and provide good flow characteristics at a wide range of RPM.

Depending on the desired cosmetics and performance any of these choices can be the right one for a given project. The builder can choose from original or aftermarket single 4-barrel, dual-quad, three 2-barrels, six 2-barrels tunnel rams or cross rams single plane or dual plane aluminum or iron. With an original manufacturing and performance use history that extends over a 50-year period, virtually every intake fashion and style has been produced for the FE, albeit in far fewer variations than for the more popular engines. The FE manifolds are comparatively wide and heavy, and have numerous machined surfaces that interface with the heads, block, distributor, valvetrain, and valve covers. One third of the valve cover extends over the intake casting, and the pushrods run through cast or machined passages in the manifold. Ford FE intake manifolds are unique to this engine family, and instantly recognizable when compared to any other engine’s parts. ![]()
