Dropping a Coyote  Engine into a Vintage Bronco

What do you do when you have a vintage Bronco and want stronger V-8 power? You probably look to Mustang engines. But what if you already have a hot rod pony powerplant and want more?

Perhaps a Coyote crate engine. This “Aluminator” engine is a 5.0L Four-Valve unit with an 11:1 compression ratio and comes complete with a manual transmission engine injector harness. Lamb Fab pulled the existing engine and started working to fit the wider, modular Ford V-8 under the hood. The work required modifications to the fender wells, front cowl, steering shaft, and front driveshaft along with will all the other usual changes that have to be made when a different engine is swapped in.  Front Runner Pulley system

For this swap, the Coyote engine was mated to a six-speed auto. This, in turn, was adapted to the existing Dana 20 transfer case that has a twin-stick shifter setup.

Follow along as we detail some of the tasks needed to complete this swap. The results are impressive, to say the least. With 435-plus horsepower on tap, there are plenty of ponies to make this Ford Bronco swap move rapidly. With the backing of the six-speed, the engine is always in powerband and drivability is awesome, especially when compared to the older three-speed C4 auto it had previously. It is supersmooth now.

The complete powertrain is temporarily assembled for test fitting. It is a clean setup adapting modern to vintage for this classic Ford. The six-speed auto transmission In the final configuration, driveshaft lengths were unchanged. However, some mods were made to the front driveshaft to clear the larger transmission. No CV joint was used, but high-angle U-joints were needed.

An adapter was sourced to mate the modern auto transmission to the Dana 20 that was already in the Ford Bronco swap. Multiple bolt holes on the adapter allow for numerous clocking configurations to place the t-case at almost any angle relative to the transmission.

To best mate the engine to the Coyote Bronco swap frame rails and make moving the engine in and out easier, an engine cradle was fabbed under the oil pan that bolts to the full-metal engine mount plates using urethane bushings. The cradle then sits in a set of pocket brackets on the frame rails. Determining the final engine placement took some time to ensure that the hood, radiator, and firewall clearances were maintained.

Ford Racing headers were used but modified a bit to fit around the inner fenders and steering shaft.  Cut off and reworked some of the tubes as needed.

bronco-headers

The Coyote engine computer itself monitors water temperature and oil pressure.  Autometer gauges used in the dash. The mechanical water temp sensor was plumbed into one of the heater ports on the new engine.

Since the Coyote engine was primarily designed for late-model Mustangs that use electric power steering, no steering pump is provided on the engine. Use of a Vintage Air Front Runner Setup includes the Power Steering Pump.

As work progressed, the engine was placed in and pulled out of the engine bay a number of times for fit checks. The Coyote engine is a good bit wider across the cylinder heads than the older 302 V-8 it replaces. The Coyote Bronco swap uses a 1980s Ford 2WD steering box and a Borgeson shaft. The position of the Ididit steering column had to be modified, as did the inner fender panel in order to push the steering shaft a bit more to the driver side to clear the wider engine. You can also see the beginning of a frame mount to capture the engine cradle

The shop fabricated this simple, high-clearance mount for the adapter at the end of the transmission. It mates with two pairs of tabs on the inner frame rails and attaches with two bolts.

Coyote 5.0 Bronco Engine Swap Radiator

The radiator is from a late-model Thunderbird; it is very slim and packaged well. The Coyote engines are quite thermally efficient, so very large volumes of coolant aren’t needed. A 60-plus-psi inline electric pump was installed along the frame rail to feed fuel to the new engine.

 Coyote 5.0 Bronco Engine Swap Radiator Filler Hoses Neck

The radiator is a closed-style, having no top radiator cap. An inline radiator fill assembly was used, simply spliced into the upper radiator hose. Hoses are late-model Mustang pieces. All hoses were secured with heat-shrink hose clamps.

Coyote 5.0l Bronco Engine Swap Radiator Steam Line

These modern motors usually require a cooling system steam line. In this case, it was run with a rubber hose to a connection at the top of the radiator. This radiator also had an integrated cooler for the transmission fluid with inlet and outlet connections.

Coyote 5.0l Bronco Engine Swap Transmission Lines

A set of factory Ford steel fluid lines was mated to the automatic transmission and routed forward. They were cut off just forward of the crank pulley, and compression fittings were used to adapt to rubber lines leading to the cooler integrated into the radiator. Also tucked up on the bottom side of the engine is an OEM Ford starter. Wiring was straightforward, and the existing Coyote Bronco swap connections were all used on the new starter.

Coyote 5.0l Bronco Engine Swap Power Steering Reservoir

A remote power steering reservoir from a late-model Mustang was mounted up near the cowl on the passenger side along with a small cooler for the steering system. Low- and high-pressure pump lines were custom fabricated and run from the pump on the passenger side to the steering box on the driver side.

 Coyote 5.0 Bronco Engine Swap Shifter

auto shifter from the 2013 F-150 that’s designed to work with the six-speed transmission. Functions include manual tap-shift capability and tow/haul mode selection. The shop fabricated a metal console to mount and house the shifter, then had it covered in bed liner material to match the interior floor of the Coyote Bronco swap.

Coyote 5.0 Bronco Engine Swap Transfer Case Shifter

The transfer case shifter assembly was custom fabricated. The shifter mount is bolted to a tab point on the new transmission.

Coyote 5.0l Bronco Engine Swap Accelerator Pedal

The Coyote engine control uses signals from a drive-by-wire throttle assembly so no mechanical throttle cable routing is necessary. Installed an accelerator pedal assembly from a 2013 F-150.

 5.0 Coyote Bronco Engine Swap Battery Computer Harness Fuse Box

A Ford Racing engine harness was used along with the engine computer. It was programmed and sits on the passenger-side wheel well just ahead of the battery. These units are designed to survive heat and vibration under the hood, so mounting here is no problem. A Bussman fuse box on the inner fender provides overcurrent protection and cleans up the power supply wiring.

5.0l Coyote Bronco Engine Swap Radiator Cowl Photo

Along with using the slim radiator with the new engine, cut out much of the original cowl.  then bridged the area with a new cross member that preserves the strength but is much more compact.

5.0 Coyote Bronco Engine Swap

The air intake was put together from generic air intake fittings, and a large Spectre open element filter was isolated in a cold air box. The finished engine swap looks super clean sitting in the Coyote Bronco Swap. It fits, but there’s very little leftover airspace under the hood.

To help better assist with lifting the engine, we have our Coyote Lift Brackets available for purchase. Coyote 5.0 Lift Brackets are properly curved and shaped so when lifting up the 5.0 V8 Coyote engine its evenly spaced.  Easy to Use. Can store very easily too. Otherwise lifting with Chain makes it very difficult to lift evenly!

It’s gotten easier  to drop a modern Coyote engine fitted to a

  • vintage Mustang
  • Fox body Mustang
  • Restomod project.

There is no argument that the 5.0L dual overhead cam (DOHC) from 2011 to 2017. Mustang GT known as the “Coyote” modular V-8, is great.

So with Over 435 hp without the use of a supercharger,

  • The Coyote’s cylinder head design,
  • camshafts,
  • and trick electronic valve timing control
  • each cam  controlled with independence

This means a new modular not only made good power but actually had usable torque down low. Something the Mustang was missing since its pushrod days.

The Coyote is a wide engine to fit into the engine bay. There are several schools of thought here, including all-new front suspension systems. They remove the shock towers completely, or strut-based front suspensions. It requires the very top of the shock tower to keep, but the rest can be trimmed back for engine clearance. The strut-based systems are a bolt-in. Though cutting and welding are required for trimming the shock towers. The complete front suspension conversions need a fair amount of welding and chassis prep. If your front frame rails are in rust. Or you have other structural issues a full front subframe conversion might be an option for you. Or a complete perimeter frame conversion.

Once you have your Coyote 5.0L in place and the last few issues to actually getting it wired up to run. You’ll need to figure out cooling system routing and plumbing,

engine inlet routing,

and if you are going to add or adapt to your power steering, power brakes, and A/C, and if so, how to do that.

on the last, you have the transmission decision. The Coyote you can fit with many manual and automatic transmission options. Most are a direct bolt in with the proper installation kit. Or adapter from several performance transmission resources.  which we’ll go over in the captions. So fear not! A Coyote 5.0L swap is becoming as popular an engine swap as ever. It gets easier by the day as new products aimed at helping the swap become a reality in your driveway hit the market.

Coyote with Power Steering Only

First thing’s first, you need the Coyote 5.0L engine.

Coyote Crate Engine Supercharger

If you’re looking for a little more go-power, A Supercharged Coyote 5.0L crate engine is available. We have a master warehouse of Edelbrock.  Go directly to this link for the 700 HP Coyote Street Beast

t56-conversion

For transmission, you’ll first need to decide if you want to go manual or automatic.

The Tremec TKO-series transmission is available. These are with carbon-fiber rings to allow the higher rpm shifting which the Coyote is capable of. A low-profile top plate conversion also allows easy installation of the TKO. All this without modifying the transmission tunnel. This Coyote kit includes cross member, bell housing, clutch, fluid, fasteners, and more. More Details on the 5 Speed Kit Here Shown here is the Tremec Magnum six-speed kit. The late-model GT500 Mustang six-speed in an early Mustang means.

  • having to cut the top of the transmission tunnel,
  • change out or remove the floor support,
  • and more to get the correct driveline angle.

Most go with the 5 speed for an easier swap, plus the 6 speed does rarely get utilized.

4R70W Coyote Automatic

When it comes to automatic transmissions. Yes, the venerable C4 three-speed automatic will bolt up to your Coyote with bolt-on bell housing. But the 4 speed 4R70W is more ideal everything you need to get it behind your Coyote. It includes 

  • Smart Shift electronics,
  • manual lever sensor,
  • block plate, flexplate,
  • converter,
  • and attaching bolts.

Fitting the more modern overdrive automatics into a vintage Mustang is nothing new.

The Coyote is a drive-by-wire modular engine,  the AOD its a throttle valve (TV) shift control cable. They are not suitable for this application. A constant pressure valve body, which does not need the TV cable operation. It would rectify this issue, but you’re better off stepping up to the 4R70W.

  • With the 4R70W, Ford builds one tough overdrive automatic. Learning from the AOD’s weaknesses and improving on its strengths. The 4R70W handles 700 lb-ft of torque in stock build. Configuration and features a wide-ratio gear set (the 70 and W in the name in accordance. Add an aftermarket controller, you can adjust shift points,
  • shift feel,
  • converter lockup,
  • and more by turning a knob.

No more dropping a valve body a dozen times tweaking springs and hoping you got it rightYou can purchase the entire  4R70W conversion kit here.  It’s becoming the “go to” automatic overdrive swap choice even behind traditional pushrod engines.

The Ford 6R80 six-speed automatic found behind the Coyote in 2011-2017. Mustang is an option, albeit one that will need some floor pan surgery and a way to control it. The floor pan modification is nothing a good fabricator. It can’t make once the driveline angle is set. But know that the taller or wider transmission tunnel might make fitting a stock console. Or even stock carpeting/seats an issue. The biggest problem with the 6R80 is controlling it. There is currently a plug-and-play standalone controller for the 20011-2014 coyote.

control_pack

As mentioned earlier, wiring the Coyote is a breeze if you use the Control Pack kit. It includes;

  • The body harness,
  • Inlet ducting
  • And air box,
  • Drive-by-wire throttle pedal,
  • Oxygen sensors,
  • And fuse box.

Once connecting, the harness to the crate engine and the pedal. You will have about six wire leads to connect to power the engine.

vintage-air

If you look back at our lead image to our story you’ll see the Ford Performance. The Coyote crate engine does not come packaged with any drive accessories. Ford offers an alternator kit with drive belt for the Coyote. Which includes the Boss 302 alternators, high-tension belt tensioner, and serpentine drive belt.

If you’re running manual steering and no A/C, the alternator kit is all you need. But if you’re looking to go all out with full accessories then you’ll need to investigate an aftermarket arrangement. One such setup is this Front Runner system.  The kit uses the industry standard Sanden A/C compressor and GM Type II power steering pump.  Along with custom brackets and spring-loaded belt tensioner. To offer a very compact setup on the passenger side of the engine.

5.0 Coyote Engine Swap Kit

coyote-oil-pan-kit

Getting the Coyote down on the mounts for many of the IFS setups. It means swapping out the production rear sump oil pan for a front sump pan.  Canton Racing has the perfect answer with its new Coyote swap pans for vintage applications. Check with your suspension provider first. Though to see if they have a preferred pan that fits their suspension. Or if the stock pans will work with their cross member.

Long tube Coyote Headers

Some builders use the stock iron manifolds. This is all for the beginning of their exhaust fabrication with an engine swap. The stock manifolds on the Coyote, are a sort-of Tri-Y setup. Interfere with the chassis and steering. The best solution right now is a set of swap headers. With the Coyote swap headers for 1965-1973 Mustangs from Doug’s Headers.  And you designed it to fit the TCI and Heidts Pro-G IFS systems, though they may work with other suspensions.

Phantom Fuel pump kit

To feed that Coyote 5.0L’s EFI you’re going to need to completely revamp your vintage Mustang’s fuel system. The stock single feed line is not EFI capable.  It is not to mention you’ll need a return line to the tank, a high-pressure EFI pump, and more. You have a few options here, one being the Aeromotive Phantom fuel system. In a nutshell, it is a pump, mounting bracket, and sump in one unit. Simply cut a hole in your tank and drop it in. Aeromotive offers the Phantom by itself and as a kit with EFI regulator, fittings, filter, and more. Add the length of -6 AN hose you need and an adapter fitting for the fuel rail and you’re all set.

Coyote fuel return

This is the Aeromotive fuel rail adapter for the modular engine like the Coyote. Slip the adapter into the open fuel rail on your crate engine until it locks in place. The opposite end is machined with a male -6 AN fitting for a standard AN hose connection. The Coyote, being returnless fuel from the factory, only has one fuel rail connection. So the fuel line routing needs to be set up. The fuel return line comes off of the fuel pressure regulator. With one pressure line connecting to the engine.

Mustang Coyote Motor Spec

coyote-radiator

Cooling the Coyote 5.0L in your swap isn’t much difficult. You only need to understand the unique cooling hose routing of the Coyote.  Ensure you either use a Degas tank or have your radiator fill point be the highest part of the cooling system. Since the Coyote, and all modular engines, the company designed to use an electric fan. That’s what you’ll have to do as well—buying a radiator and fan combo is your best bet here. C&R Racing offers a Coyote swap radiator. The C&R-based unit bolts to existing core support holes.  They only need two small holes to get drilled in the bottom of the support. We’ve also used custom-built units from Flex-a-lite for modular. Coyote builds as well with great results.

suspension

So you’ve figured out your engine and transmission choices and now you’re ready to go, tools in hand. If you haven’t noticed actual fitting the Coyote into your Mustang. Then that is going to need some reconfiguring of the engine bay. A popular route is a new independent front suspension (IFS). It relocates the spring to the lower arm and eliminates the shock/spring towers. There are a number of companies that offer solutions.  Total Cost Involved (TCI) Engineering. The TCI Engineering system welds into the front frame rails. Then the suspension pieces bolt to the new subframe, providing ample clearance. The Roadster Shop offers its own IFS that utilizes modern Corvette spindles. A splined antisway bar, and other high-end goodies for a suspension. That not only allows Coyote fitment but can easily tackle the road course as well.

Ford 5.0 Mustang Coyote Engine

detroit-speed

Detroit Speed’s Aluma-Frame IFS is another, very capable IFS. That person can consider as well and comes ready to fit the Coyote engine. The aluminum subframe structure bolts to the stock frame rails. Then sandwiches it after welding on the mounting plates. Detroit Speed’s instructions offer several part numbers for Coyote fitment, including,

  • Headers,
  • Oil pan, and more.  

Rod & Custom Motorsports was one of the first IFS manufacturers. They offer a Coyote-specific IFS package.  And now they offer a right-hand-drive configuration for those countries that need it.

The dual A-arm IFS setups are a popular route. Many Coyote swappers prefer a strut-based front suspension. With a strut IFS, you do have to maintain the very top of the shock tower, as it is the mounting point for the top of the strut. But the remaining shock tower you can cut back for engine fitment. As installed, you can see the Coyote clears fine with the shock tower simply trimmed back.

Coyote Motor Swap

Fatman Fabrications has an interesting offering for strut IFS builds. Its modular system uses a series of bolt on tubular supports. And stamped metal panels to completely reform the engine bay. It offers the most clearance for the wide Coyote. Bolt on engine mount adapters and firewall/core support bracing includes in it.

coyote-in-chassis

You are thinking all-new suspension front and rear for your Coyote build. You might want to forego the typical suspension kits. You need to upgrade a full perimeter frame. Offering like those from the Roadster Shop and Schwartz Performance. Simply trim away your stock front shock towers and frame rails. Weld a few mounting tabs to your Mustang’s unibody, and bolt it down on this performance frame package.

Throttle pedal Coyote

The Control Pack needs a drive-by-wire pedal. It will need you to mount thorough a custom-fabricated mount. This is an earlier pedal shown installed here, but it gives you an idea of what needs to complete. This fabbed bracket from steel sheet and bolts welded to it as mounting studs at the top and a nut for a bolt at the bottom.

coyote-air-inlet

One part of the Control Pack will be the airbox and possibly the inlet ducting. Depending upon accessory mounting an engine bay you might be able to get an aftermarket cold air kit to work. Like this JLT (www.jlttruecoldair.com) system shown here on a 2013 Coyote Mustang GT with a little fuss.  Alternatively, you can fab your own inlet tubing and add a mass air sensor mount and a filter to the end, as in the case of this Coyote install in a 1967 fastback. Several companies offer universal tubing, mass air sensor mounts, and filters. Gateway Classic Mustang offers a Coyote in a vintage Mustang cold air kit too, ready to go.

brake-master-cylinder-coyote

One area that can be a bit of an issue is the brake master cylinder. Due to the massive width of the Coyote 5.0L even using a manual brake master cylinder.  It’s mounted to the firewall can be an issue, especially in 1965-1966 applications. This is due to the near flat mounting surface of the 1965-1966 firewall versus the recessed mounting area found on the 1967-1970 firewall. The answer is to move the master cylinder over roughly 1 3/4 inches.

This will need widening the pedal support, adding length to the brake pedal arm pin, and moving the clutch pedal over as well. If it’s a manual trans car. You can see in these photos, how they moved the master cylinder over and modified the brake pedal and support accordingly.  For the 1967-1970 firewall, the master cylinder will bolt directly to the OE holes and should clear the cam cover. Ensure you use a master cylinder with outlets facing the inner fender and not toward the engine. Stang-Aholics uses this dual reservoir unit from ABS Power Brake in their swaps.

Fox Body Coyote Swap

master-cylinder

Speaking of power brakes, as you can imagine, there is no way you’re getting a traditional vacuum diaphragm booster in such a tight spot. We’ve used hydraulic assist units in previous builds, aka hydroboost. But they need power steering and some additional line plumbing. Though they work great. A new, more compact option is a remote hydro-electric setup. Stang-Aholics uses this setup from ABS Power Brake that utilizes a small reservoir,

  • an electric pump,
  • and a high-pressure accumulator

to provide a true power brake pedal feel.

coyote-cooling

Most of the coolant hoses come with the harness kit.
