Sibling come the 429, which was the critical true muscle car huge block built by the Blue Oval, the an enig to the 460"s success was its ability to churn out hills of torque even when hobbled by "70s-era emissions equipment.

Today, the 460 V8 sit as among Ford"s finest kept secrets. While the 5.0 small block can get many of the attention, adhered to by its contemporary Coyote cousin, this big block has actually a lot to offer project building contractors seeking something different.

385 changes The Game

Both the 429 cubic inch and 460 cubic inch V8 come from the 385 series of engines that hit the scene in the so late 1960s. The brand-new engines mutual the exact same bore but featured a various stroke (the 3.85 customs measure that offered the family members its name. Other differences contained stouter building in the 460, which to be intended generally to be supplied in high-end sedans where all at once weight wasn"t as much of a issue (with the engine check in in ~ a whopping 720 lbs). You can thank the overbuilt motor"s actors iron heads and three-inch main bearings for lot of its mass, yet it"s precious nothing that in basic the 385 family members of engines was lighter than both the FE and also the MEL large blocks that had come prior to them at Ford.


Also known as a "Lima" engine due to its manufacturing at Ford"s Lima, Ohio factory, the 460 kept posh agency during the first couple of years that its life. Accessible exclusively in Lincoln products, it provided 365hp and also 485 lb-ft the torque because that the Lincoln Continental note III coupe and the continent sedan.


Although those to be both gross power ratings, in maintaining with the requirements of the day, the 7.5L engine ceded exceptionally smooth power and acceleration in these heaviest that Lincoln floor barges.

Joining The Family

In the early on "70s Ford do a variety of changes to the 460"s design and also its availability. Mercury would be the very first to obtain the motor in that is full-size and also mid-size vehicles in 1972, followed by Ford the complying with year (which would offer it in both passenger vehicles and also trucks).


At the very same time, native "72-onwards Ford tinkered through the motor and choke output considerably. Fitted through a new camshaft and also a reduced compression ratio, Ford"s best mistake was a head architecture for that year that would certainly virtually eliminate the quench area, which lead to countless problems through reliability and detonation and also forced a complete redesign because that 1973.


Using the new "SAE net" speech rating the 460 coasted along around the 200 pony mark for much of the remainder of the decade, with torque measured at just under 350 lb-ft.


In 1978 Ford pulled the 460 from every one of its passenger vehicles, Mercury and also Lincoln included. Trucks and also vans, ~ above the other hand, continued to benefit from the motor because that the next two decades, through power climbing to 225 ponies in 1983 and also then 245 a couple of years later on (with torque farming to 385 lb-ft). In 1988, the 7.5L mill take it a major step forward in regards to performance thanks to the advent of fuel injection, which witnessed both speech (245) and also torque (400 lb-ft) peak in the modern-day era through the 1990s. This numbers remained healthy all the means until 1997, as soon as the engine left the pickup and van portfolio.

An Underrated hot Rod Option

From a modern-day perspective the Ford 460 big block is cheap and also plentiful, making that a tempting target because that Blue Oval builders. V so countless trucks and huge cars having actually made usage of the engine, it"s simple to find, and there space a organize of performance parts now easily accessible that an ext than consist of for the post-smog architecture flaws. Although the engines space dimensionally fairly large, they are fairly low and flat, which renders them less complicated to to the right under the hood of a wide variety of vehicles, including Fox platform models choose the Mustang and also the Thunderbird.


Key to building any kind of 460 V8 is proper flowing heads. The earliest share heads (C9VE or DOVE castings) administer the finest factory flow, yet there room plenty the aftermarket choices out there, consisting of aluminum systems that are considerably lighter 보다 the initial Ford monsters. Properly-sized exhaust port are crucial when installing a hotter camer in the 460, together "70s-era designs (which offer great intake area but poor exhaust restrictions) merely can"t breath deep sufficient to complement the demands. Trick Flow, Ford Racing, and Edelbrock all make high performance heads that fit the big block.

Some builders likewise opt to walk the stroker path with the 460, which can lead to displacements of approximately 545 cubic inches for those seeking low-rpm speak that will certainly rattle the home windows of whatever within a 2 block radius. With the right carb setup, or a stand-alone electronic fuel injection system, it"s basic to punch out 500hp from the 7.5L motor—more than enough grunt to have actually some severe fun in a cruiser or a drag automobile on a reasonable budget.
