Ford 2.8L Engines
About The 2.8L:
The Ford Cologne 2.8L V6 is a 60° cast iron block V6 engine built by the Ford Motor Company in Cologne, Germany. The 2.8L engine in the Ranger is the same design as the 2.8 V-6 used since 1974 in the Ford and Mercury Capri vehicles. A unique feature of the 2.8L is the timing gear vs a traditional timing chain (See picture below).
(Ford 2.8L - Timing Gear Shown)
Firing Order 1-4-2-5-3-6 / Distributor Rotation - Clockwise
Valve Seals - The 2.8L's are known to burn oil and smoke when they get high mileage. They use a rubber valve seal that deteriorates and leaks oil into the cylinder. Click HERE for information on replacing the valve seals.
Loose Distributor Rotor - Some of the Ford 2.8's came with round distributor rotors. These have (2) screws that hold them in place. There have been reports of them coming loose in the distributor. Click HERE for more information.
TFI Failure - If your truck stops running and wont restart, it could be from a faulty TFI. Click HERE for more information.
Cooling - A simple upgrade to the 2.8L heads is to drill two more water passages in them between where the two exhaust valves are side by side. This helps prevent a local boiling point from forming. Just use a good head gasket that already has the water passage holes in them for a guide, and mark the head and drill two holes. Keep the holes a little smaller than the holes in the head gasket. - Contributed By Ryan Propst
Porting - Port your intake manifold and cylinder heads. The intake and heads don't line up diameter to diameter. Porting opens this up and allows better flow. Click HERE for details on porting.
Induction - Offy 4bbl Intake:
The 2.8L V-6 comes with a 2-bbl carburetor and manifold with a traditional round metal air filter container. Offenhauser offers a 4bbl intake manifold. The ignition system must be changed to earlier vacuum advance unit (Dura-Spark II) eliminating the EEC-IV computer and pollution equipment. You can use the distributor, ignition module and coil from a 78 Pinto. The Offenhauser Intake does not have an EGR setup. This will not allow the A4LD tranny to shift correctly.
The Offenhauser intake can be found at:
The Racer Walsh 2.8L aluminum intake manifold is made to work with the RWA6239 4BBL carb. You will need to use the RWA6278 thermostat housing with the new manifold. The intake manifold and carb combo are made for street driving and lower rpm off road applications, such as trail riding and playing in the mud. The installation of the manifold and carb still provide good gas mileage and an easy horsepower improvement.

Performance Automotive Warehouse (www.pawengineparts.com) did carry Offenhauser 4bbl Intake Manifold Part Number 0FF-6097-DP (part of Port-O-Sonic line). Unknown if they still carry it.
Induction - Fuel Injection:
You can also swap on fuel injection using parts from a 3.8L Ford. Check out the 2.8 Fuel Injection page.
Competition Cams carries (3) camshafts for the 2.8L Ford, the 244S, 252S and 264S. Cam descriptions can be found HERE. Those parts can be found at Jegs (www.jegs.com) by searching for those (3) part numbers.
Competition Cams carried camshafts, rocker arms and timing gear for the 2.8L HERE.
THIS PAGE is the main Comp Cams menu for the Ford V6.
Camshafts - Racer Walsh (Also see below):
Racer Walsh offers (2) camshafts for the 2.8L Ford.
The stage 1 cam gives a smooth idle as well as a boost in low to mid range power, without sacrificing fuel economy. Please specify the year of your engine when ordering.
The Racer Walsh stage 2 V-6 camshaft for the 2.6L/2.8L engines offer a significant power increase from the midrange to top end performance. The Racer Walsh Stage 2 camshaft is a street / competition grind. We recommend a slightly higher than stock stall on the converter if an automatic transmission is used. Please specify the year of your engine when ordering.
Racer Walsh carries 9-1 pistons for the 2.8L Ford HERE.
Exhaust & Air Filters
Motors are just big air pumps. The more air and the more air out the better the performance.
Summit Racing also carries a Dynomax cat-back exhaust kit for the 2.8L.
The air cleaner can be modified by adding another air intake and then routing intake hoses to a fresh air source providing a dual ram air effect. This of course should be accompanied by a K&N Air Filter. There are many 2-bbl air cleaners out there of different dimensions, and it's metal design allows for modifications for any type of set-up.
Summit Racing carries Jacobs, Mallory, MSD and Summit TFI harnesses to install an their aftermarket ignitions to your TFI vehicle.
Jacobs P/N JAC-380465
Mallory P/N MAA-29062
MSD P/N MSD-8874
Summit P/N SUM-850518
Click HERE to see them at Summit Racing.
MSD-8874 Shown Above
The MSD to Ford TFI Coil Harness is designed to provide a splice-free and simple installation of an MSD Ignition Control to Ford vehicles equipped with a TFI Coil. On MSD 6 & 7 Series Ignitions all of the wires connect to the corresponding colored wires. MSD 7 Series Ignitions share the same color wires.
1. Disconnect the connector from the coil and connect it to the MSD PN 8874 Harness.
2. Connect the other end of the Harness to the Coil.
3. Connect the four wires of the Harness to the MSD Ignition Control.
MSD Ignition Box Shown Above
Summit Racing carries replacement TFI ignition coils. You can view a list of them on the Summit Racing site HERE.
TFI Ignition Modules:
Summit Racing carries Accel and PerTronix TFI Ignition Modules.
PerTronix P/N D2010
Accel P/N 35368
Accel P/N 35368 Shown Above
ACCEL control modules provide high coil output & superior reliability. Dwell circuit ensures long coil charging. Current circuit protects from overheating. Resists false triggering from RFI sources. Distributor and remote mounts available.
Available at Summit HERE.
Summit also offers Pertronix P/N PNX-D2010 HERE.
Spark Plug Wires
You should upgrade to 9mm spark plug wires and will have to purchase a set of JBA Powercables or get a set of universal wires and cut them.
Summit Racing carries the JBA Powercables P/N JBA-06309 HERE.
Duraspark Ignition Swaps:
Also check out the Duraspark ignition conversion HERE. Using the Duraspark ignition, you can eliminated the computer, vacuum rail, vacuum reservoir, and all the wiring mess that goes along with that. Get the carburetor that is on the 2.8 donor engine your Duraspark ignition comes from. The Ranger 2.8 has a complicated carburetor control system.
