Ford Motors V8 supplement FE & FT 2 of 4

Two months before any other Ford product carried it, the FE V8 made its debut in the unlikeliest of cars: the all-new 1958 Edsel. From there it split into truck duty, police-package cruisers, and factory tri-power setups shipped loose in the trunk, before a redesigned block gave rise to the short-lived but influential 406. Read on to find out how a workhorse engine family quietly built the foundation for Ford’s most feared big-blocks.

Two months. That’s how far ahead of schedule Ford rushed a brand-new engine family into production in the fall of 1957 — and it wasn’t tucked under a Mustang or a Fairlane. It debuted in a car most enthusiasts have spent sixty years trying to forget. Before the FE engine ever powered a muscle car, it was pulling police cruiser duty, hauling farm trucks, and quietly setting up the architecture that would eventually produce some of the most feared big-blocks Ford ever built. The story of how a workhorse truck motor and a forgotten sedan engine evolved into 401-horsepower street iron is buried in Ford’s parts catalogs — and it’s worth digging up.

A New Engine Family Debuts in the Last Car Anyone Expected

The FE engine family’s true debut came on September 4, 1957, when the all-new 1958 Edsel went on sale to the public powered by the brand-new FE 361 (5.9-liter) V8 — a full two months before any other Ford product would offer an FE or FT engine. Mounted with a four-barrel carburetor, the 361 wasn’t built with drag strips in mind. Ford engineered it for institutional buyers first: law enforcement and emergency services departments ordered it as the “Police Power Pack,” sold both as single units to individual departments and in volume through fleet agents at Ford dealers across the country. It was heavy-duty by design and spartan on luxury — everything about it said durability over comfort, which is exactly what a patrol car needed in 1958.

The Truck Engine Hiding in Plain Sight

While the 361 was chasing police contracts, Ford quietly built a parallel FT variant for trucks: the 360 cubic-inch (5.9-liter). It shared the 390’s 4.05-inch bore but used the shorter 3.5-inch stroke borrowed from the 352, and the only reliable way to tell a 360 apart from a 390 without measurements was by checking crank stroke length — the two engines looked nearly identical on the outside. With a two-barrel carburetor, the 360 produced 215 horsepower at 4,200 rpm and 375 lb-ft of torque at 3,600 rpm, modest numbers built for hauling rather than racing. Ford offered it in pickups from 1968 all the way through the end of 1976, a testament to how well the FE/FT architecture aged as a workhorse platform even after its performance variants had moved on to bigger displacements.

The 390 Splits Into Two Very Different Personalities

The FE 390 cubic-inch (6.4-liter) became the workhorse of the lineup, popular enough that it’s often overshadowed by the 427 and 428 despite serving in far more vehicles. With a two-barrel carburetor it made 265 horsepower at 4,100 rpm; swap in a four-barrel and the rating jumped to 320 horsepower. That four-barrel version found its way into the 1967 and 1968 Mustang, where it carried a 335-horsepower rating — a serious number for a car that started life as a secretary’s special. The 390 could flex considerably depending on tune, and that flexibility is exactly what made it Ford’s default big-block for most of the 1960s.

When Ford Hid a Tri-Power Setup in the Trunk

In 1961, Ford built a genuinely aggressive version of the 390 — solid lifters, 10.5:1 compression, an aluminum intake manifold, a four-barrel carburetor, and cast-iron header-style exhaust manifolds, good for 375 horsepower. But the most unusual factory trick came with certain Galaxie and Starliner models — the tri-power kit’s real home in 1961, since neither the Fairlane GT nor the Mercury Cougar existed yet, which shipped from the factory with an aluminum tri-power intake manifold — set up for three two-barrel carburetors — sitting in the trunk rather than installed on the engine. Bolted on, that setup pushed the 390 as high as 401 horsepower, turning a dealer-lot sedan into something considerably more serious once the owner, or a friendly mechanic, did the installation.

A New Block Casting Changes the Math

By 1962, Ford introduced what amounted to a second-generation FE big-block: the 406 cubic-inch (6.65-liter), technically 405.7 cubic inches rounded up for marketing purposes. It kept the 390’s 3.785-inch stroke but rode on an entirely new block casting with thicker cylinder walls and a larger 4.13-inch bore. From the outside, a 406 and a 390 look nearly identical — the difference lives entirely in the casting.

Cross-Bolted Mains: An Idea That Outlived the Engine

The 406’s real engineering contribution was underneath: cross-bolted main bearings, held not just by bolts from below but also by bolts running through the side of the block casting itself. Ford added a spacer, or shim, between the face of the block and the end cap specifically to stop the cap from “walking” under the punishment of sustained high-rpm racing use. It’s a detail that sounds minor until you consider that variations of cross-bolted main bearing designs are still used today by manufacturers building some of the most powerful racing engines on the market — a 1962 solution that never really went out of style.

A Two-Year Engine With an Outsized Legacy

For all its engineering, the 406 had a remarkably short production run — less than two years before Ford replaced it with the 427 in 1963. That brevity makes surviving 406-equipped cars a genuine rarity today, and it positions the engine as something of a missing link: the bridge between the FE family’s early, institutionally-minded 361 and 360 variants and the all-out 427 that would go on to define Ford’s performance reputation through the rest of the decade.

Why the FE Family Still Matters to Collectors

What makes the FE/FT story compelling isn’t any single engine — it’s the range. The same basic architecture that pulled patrol duty in a 1958 Edsel and hauled cargo in a work truck through 1976 also, with the right castings and carburetors, produced a 401-horsepower street engine and paved the way for cross-bolted 427s. For collectors and restorers today, knowing exactly which FE variant sits under a given hood — 360, 390, or 406 — isn’t academic trivia. It determines the car’s correct build sheet, its period-correct parts, and often its value, since a numbers-matching high-output 390 or a rare short-run 406 carries a very different story than the common two-barrel version most FE-powered Fords left the factory with.
