INTRODUCTION

Building, or rebuilding, an engine is a significant task to take on under any circumstances. There are plenty of great reasons to do it, ranging anywhere between financial necessity and the personal satisfaction of completing a complex and challenging job. Once you’ve made the commitment to build your engine, a broad range of possibilities (economic, cosmetic, and performance) must be considered.

This book is targeted toward the more basic engine-building project. It could be a completely stock rebuild for a cruiser or daily driver, a restoration-style build for a muscle car, or a comparatively mild hot rod engine build. I anticipate the reader of this book to be working in his or her home shop or garage and to contract out the more sophisticated machine work. As your projects get more complex, or as performance needs grow, I suggest acquiring the Max Performance series of books for additional information.

At points in the building process you will be handing off the parts to a machine shop to cover work that you either cannot or should not try to handle at home. Discussions of the process with your chosen shop are important, and you will want to establish a good working relationship with them. How much of the work you have them take care of is predicated upon your budget and desired outcome. If you choose to do some of the work yourself using home-style techniques, just be cognizant of the potential impacts to your results. Throughout this book I list certain processes or products as “need to do,” “nice to do,” or “do if you wish.” Sometimes saving a few bucks simply is not worth it.

This book is dedicated and directed toward the rebuilding of the Ford FE series of engines, but many of the procedures and concepts can be applied to any engine-building project. Throughout the book I try to point out and compare some options in terms of relative need versus cost or benefit. Often, several different acceptable methods can lead to a successful end result. I usually use a couple simple euphemisms to describe and evaluate choices for the task at hand. The guys at my shop hear the following sayings frequently.

This book will illustrate the processes for rebuilding your FE engine, but at some point, you will need the help of a machine shop or engine builder to complete the task. While not a requirement, it is always best to try to find a shop that has experience in building the same type of engine that you are working on.

The first one is “good enough really is good enough.” I’ll use this phrase to indicate that certain parts, processes, or methods may be inarguably better than other choices while not being at all necessary for a given engine build. You can view this as being a “good, better, or best” selection process, or as insurance, or as an investment toward future plans.

Another frequently used comment I make is that a particular part represents “a solution looking for a problem.” In the world of marketing there will always be folks trying to differentiate their product by making claims of better cost, performance, or longevity. If you read claims of huge benefits from a rather mundane and well-established product, it’s usually a good bet that they are overstating their case to make the sale.

The last one I’ll mention here is my use of the concept of “risk versus reward” as applied to engine building. Risk can be viewed as excessive cost, missed opportunity, or inadequate parts for the intended use. The “reward” has to be viewed in the context of the engine we are working on. In the racing world, engines have been refined to the point that any incremental gains are coming in very small increments. A $1,200 piston ring set that delivers 4 hp more to a professional race team has no real significance to a guy freshening up the engine for his pickup truck.

FE Engine History

The following is largely taken from the Max Performance FE book published a few years ago, and serves as a useful introduction to the history of the Ford FE engine. Throughout these pages you will occasionally find a comment or photo from that book, which makes sense, given they share the same author and publisher.

The FE Ford engine was released into production in 1958. The earliest applications included use in the short-lived Edsel program. The FE was not a replacement for the Y block; it was a larger companion engine family sharing some design features. In 1958, the Y block was still considered a current design at only four years old.

Starting out at 330 ci, the FE quickly grew in displacement through its first five years of production, with 352-, 390-, and 406-inch variants followed by the now-famed 427 in 1963. By 1966, the release of the 428 and the short-lived 410 completed the variety of basic passenger car combinations. A lot of high-performance history was written in a very short time. The 352 and 410 were dropped after 1966, and the 390 and 428 continued as the only FE engines in passenger car production from 1968 through 1970.

The FE had been dropped from passenger car use by 1971, but the 360 and 390 versions remained extremely popular in pickup trucks through the 1976 model year. Some commercial applications, notably U-Haul trucks, had FE power through the 1978 model year. Throughout the 20-year production run, the FE saw use as a marine, commercial, and industrial engine as well.

While the high-performance factory engines were responsible for all the glory, most production was for more mundane applications. Certainly the most popular original FE vehicles were full-size family cars and pickup trucks; they serve as the source for most of the engine blocks we start with today.

The beginning of the FE performance program had its roots as Ford split the car lines during the late 1950s, going from one basic platform to many as the market developed. The emergence of the bigger cars coincided with a gain in popularity of motor racing. The NHRA U.S. Nationals were held at Detroit Dragway in 1959 and 1960, and auto executives were exposed to the rising popularity of the sport. At the same time, NASCAR began the transformation that would take it from the local circuit group to national popularity. Television was about to change the way cars were marketed, and motorsports was one of the beneficiaries.

Ford responded to the market opportunity with high-performance iterations of the 352, then the 390. This was still the era where a production-based engine could be equally successful in both drag racing and NASCAR.

The FE performance program started out as upgrades to passenger car engines, using strategies that had been employed by hot rodders for several years. Higher compression, multiple carburetion, and dual exhaust were initially enough to get attention. But as the rivalry between the Big Three heated up, they quickly evolved into performance-specific engines. The first of these was the 406, blessed with a larger bore than the 390, solid lifter cams, and optional multiple carbs. Within a couple years the 406 was replaced by the 427, with a still larger bore, cross-bolted main caps, and better cylinder heads. The 427 became the lead piece for all of Ford’s big-block race development and remained in that position through the end of direct factory involvement in 1970. When discussing professional racing and FE engines, you are almost always going to be talking about the 427.

The 428 was originally released in 1966 as a torque-oriented cruiser engine, but in the late 1960s somebody at Ford finally realized that the low-production, high-strung 427 was not reaching the masses. Ford had a good race program, but was getting a bad street rep. The more mundane 390-powered cars could not keep up with the big-blocks from GM or Chrysler. The response was to blend the readily available and bigger 428 block with higher-performance parts, including heads, cam, and intake. The 428 Cobra Jet package was available from late 1968 until 1970 and delivered on all points; it was reliable, strong, and still a competitive combination in NHRA-class racing.

Ford achieved incredible success with its FE-powered racing program, winning repeatedly at Le Mans, on the NASCAR circuit, and in the drag racing arena with their 427-powered Ford Thunderbolts, as well as the 1968½ 428 Cobra Jet Mustangs.

The 429-engine family was slated to be the replacement for the FE, but the factory programs surrounding the new engine were short lived, barely making it two years before performance development stopped. Eventually the potential for the “385” family engine was realized, but that is another book.

The Famous Cars

Ford’s initial platform for FE performance and racing was full-sized cars, the most popular being the higher-end Galaxie. Many FE engines were installed in full-size cars, most of them 352s and 390s. But the racers got the 427 cars.

While the 427-powered Galaxie was a good-looking and competitive package, it became quickly apparent that the Chrysler cadre had a distinct weight advantage with their smaller cars. The first response was to develop a lightweight factory drag race version of the 427-powered Galaxie. It included a high-riser version of the 427 engine, along with a variety of weight reduction strategies, including changes to sheet metal, interior parts, and even the frame. Always rare, and quite valuable today, the lightweights were only the opening act.

The next step was a factory authorized dedicated drag race car: the Fairlane Thunderbolt. The T-Bolts were assembled at Dearborn Steel Tubing, a Ford contractor. It took the lighter-weight midsized 1964 Fairlane sedan and installed the high-riser 427 engines into about a hundred of them. This was never intended as a street vehicle, and everything was modified to enhance the car’s chances at the drag strip. Ford included major front-end work to accommodate the large engine, lightweight seats, thin glass, aluminum and fiberglass components, and race-only rear suspension. The Thunderbolt became a Ford racing icon, and the combination remains near the top of NHRA Super Stock racing 54 years later.

Ford did not install the 427 in a production Fairlane until 1966. The production 427 Fairlanes from 1966 and 1967 were rare, very cool cars with a solid racing history. But, like the lightweight Galaxie that preceded them, they never received the adulation reserved for the Thunderbolt.

Something about the almost absurd combination of small car and huge engine makes anything else seem normal in comparison. The ultimate expression of small car/huge engine is also FE-powered: the 427 Cobra. The Cobra started out as the well-documented combination of a British sports car and a Ford small-block V-8 for road racing. Competing with well-funded efforts from both domestic and foreign racers, the need for more power was satisfied by grabbing an existing race engine, the 427 FE. What had already been an attractive sports car morphed into a beauty born of necessity, with broadened and flared fenders for larger tires, side exhausts, and a scooped hood. Brutal in both potential and execution, another automotive icon was born. Today there are many, many more inspired iterations of the car than were ever originally made. The 427 Cobra was and is the automotive definition of “badass.”

Carroll Shelby first plucked the 428 Police Interceptor engines off the assembly line for use in the Shelby GT500 Mustangs in 1967. In 1968, the PI engine was replaced mid-year by the 428 Cobra Jet variant, and the car became known as the GT500KR. The 428 CJ continued through to the end of the Shelby production run in 1970. By 1969, the Shelbys were slow sellers, many unsold 1969 models were retagged as 1970 models. The cars are considerably more popular today.

NASCAR racing was the primary development test bed for Ford’s FE race program throughout the 1960s. The 427 was upgraded and altered every year as needed to remain competitive. But while NASCAR served as the engine technology source, the cars themselves were not inspiration for many production performance offerings. Street enthusiasts looked to NASCAR for entertainment, but to the drags for inspiration. So, while we’ll use parts that were designed for the high banks, we don’t often emulate the cars themselves. Street cars have the big tires on the rear, scoops on the hood, but no numbers on the doors, a tradition that holds true today.

Throughout the late 1960s, professional drag race programs evolved, and the cars got further from a production basis. The hard-core drag racers moved into AFX cars, with radical modifications to wheelbases and engines. These in turn evolved into Funny Cars with tube chassis and nitromethane. The SOHC FE engine remained a common powerplant in these, but far removed from the engines available at the local dealer. These cars and engines are certainly worthy of discussion, impressive by any measure, but outside the context of this book.

The most famous of the FE-powered cars were never really sold to the public. Ford made a very public, concerted effort to get an outright win in the 24 Hours of Le Mans race in the mid-1960s. The first cars they produced were powered by the small-block engine. In subsequent years, the need for more power became apparent. In a situation similar to that of the Cobra, Ford looked to the already well-developed 427 FE as a power upgrade to the GT racing program. And the engine delivered, powering the winning cars in 1966 and 1967.

So here we have the FE engine legacy. The engine that was in the most famed Ford racing vehicles of the time in each form of motorsports, NASCAR, the Cobra, the GT40, and the Thunderbolt. This should be the backdrop for comparable fame and dominance on the streets of America. But it never happened. What went wrong?

The Normal Cars: Mustangs, Galaxies, Fairlanes, and Trucks

As a dedicated Ford fan and a Detroit-area FE racer since the 1970s, it hurts to say this, but it needs to be said. What went wrong is that Ford put everything into the low volume racing efforts and comparatively little into the everyday cars that made up the volume of production.

The FE was factory installed or available in numerous car and truck platforms. The full-sized Galaxie (and sister models) was the recipient of most FE production, from the early 1960s right up to the end. Most popular among enthusiasts are the 1963–1967 models.

Ford’s intermediate cars, the Fairlane, Torino, and Mercury variants from 1966 through 1969, also had the FE as a regular production option. Most by far were 390-powered. A very few 1966 and 1967 models had a 427, and the 428 CJ was available beginning in late 1968.

Mustangs and Cougars were often FE-equipped from 1967 through 1970. The 1967 and 1968 big-block models were all 390-equipped. In 1969, there were a few 390s, but the 428 CJ was the engine of choice. The hydraulic lifter version of 427 was installed in a few Cougar GTEs in 1968 (replaced by the 428 CJ midyear), but no 427 Mustang has ever been documented despite 40 years of rumors.

Ford pickup trucks carried the FE as an available option through 1976. There are probably more FE engines in pickups than in any of the cars. The FE can be installed into any of the cars or trucks where it was an option. Any deserving small-block or 6-cylinder-powered candidate can be upgraded to FE power using factory replacement components.

When new, a 390-powered Galaxie of 1964 or earlier was a competitive car on the streets and local tracks. But by the 1970s, it was common knowledge that the average 396-powered Chevelle could pretty much hammer any 390 car at will. A 428 Mustang could hold its own, but most FE owners simply lost enthusiasm. They got tired of getting their butts kicked every Friday night. They moved on to other cars or other hobbies, and the cars were left to sit or used as basic transportation. Interest from the aftermarket never really took off, so the supply of new parts was not there, and the old factory parts were getting used up and worn out.

By the 1980s, the FE engine was considered obsolete by all but a few die-hard enthusiasts and racers. No mainstream magazine coverage, no new aftermarket parts, and no real development outside the private efforts of the dedicated NHRA Super Stock and Stock Eliminator racers. The engine design that had won Daytona, Le Mans, and the Winternationals was considered obsolete and in the same league as the Buick Nailhead, the Chevy 409, the Olds Rocket, and Ford’s MEL and Y block.

The Dinosaur Reawakens

But there was a difference: the cars. The Cobra was still worshiped, the Thunderbolt was still an icon, and the legacy from those early NASCAR, Le Mans, and drag racing wins still hung on. Stock and Super Stock racers running FE power continued to win with no factory support. As people started to repair, reproduce, and emulate those cars, the demand for FE parts began to build.

Specialty suppliers, including Dove, carried the FE flame through the slow years, catering to the dedicated racers and restorers. But when Edelbrock released a replacement FE aluminum cylinder head in the mid-1990s, demand finally began to build. A lot of candidate engines came from the huge truck population. And there were a lot of candidate cars to choose from.

While the 427-ci FE engine was all about dancing around redline on the tachometer, Ford knew that just wasn’t very appropriate for some of the chassis needing upgraded big-block power. For the 1966 models, Ford introduced the 428-ci engine, which was a long stroke version of the FE engine design, specializing in comfortable torque rather than high-revving horsepower. Ford used the new 428 in full-sized Fords, Mercurys, and Thunderbirds as an upgrade to the 390.

In 2004, Scat released a cast stroker crank for the FE, and Genesis concurrently released the first cast-iron reproduction 427 blocks. I built one of the first big-inch FE engines that used both parts, topping the 505-ci package with an EFI system. The engine was covered in Hot Rod magazine’s July 2004 issue as the “676-Horsepower Dinosaur.”

I entered a similar 505-ci FE in the Jegs Engine Masters Challenge the following year, using the new Blue Thunder cylinder heads. Most of the competitors thought it was pretty cool to see one of them ol’ FE motors in the contest, and at first viewed it as a curiosity. Only after it made 752 hp on pump gas was it apparent that this was not a nostalgia piece; it was a modern engine with FE architecture. We finished 8th overall out of 50 entrants and got another magazine article as a result.

Jay Brown out of Minnesota entered his FE-powered 1969 Mach 1 into Hot Rod’s Drag Week competition in 2005. This is a grueling event covering more than 1,000 miles and five drag strips over a five-day period. The best overall average ET wins, and the Mach 1 took home the class win. Brown recently repeated the feat in a SOHC-powered 1964 Galaxie.

Subsequent FE race wins, engine builds, and project cars have gotten an increasing amount of media coverage from writers looking for something different. With a full array of parts now available, it is possible to build a complete 427 FE from scratch using all aftermarket pieces. You can build a 445-ci 390-based FE stroker that’ll get you 500 honest horsepower without breaking the budget. In a few short years, the FE engine has gone from near extinction to mainstream again. This is without question the best time in the 50-year history of the FE to build one for the street.
