It’s gotten easier to drop a modern Coyote engine fitted to a Classic 1966-77 Bronco. The 5.0L dual overhead cam (DOHC) Coyote modular V-8 has evolved over the years. Improved cylinder head design, camshafts, and trick electronic valve timing control each cam controlled with independence Can deliver up to 480 HP without a supercharger, also with usable torque down low. Making it fun to drive the vintage Ford Broncos.
General Fitment Guidelines
The Coyote is a wide engine to fit into the engine bay. It’s a squeeze but does fit between the frame rails. Some modifications may include;
- Moving the steering column over approx. 1 inch for the additional clearance – ( there’s room to move without a lot of effort) upgrading to a Tilt Steering is a nice option. Would not suggest Column shifter adapters, not enough throw to select the gears. Typically using a late Model Mustang floor shifter is what most installers use. – There is a column shifter available from FFG in production if prefer
- The coyote motor mounts provided are a direct fit into the factory V8 motor towers of the Bronco engine bay.
- Majority of these Bronco Swaps use a 2-3 inch body lift ( an 2 inch suspension lift) which allows clearance of engine and transmission in bay. Using a lower profile oil pan will be necessary when dropping in a Gen 3 or Gen 4 coyote.
- With the engine installed the passenger side clearance side fender wall is tight. Some installers use weld in a narrower wheel well for added clearance.
- We provide the 4 x 4 version 6R80W 6 Speed with the Dana 20 adapter. but we don’t get involved with dana 20 shifter, there are twin shifter knobs for the 6R80w in the aftermarket.
BTW, most prefer the 6R80W 6 Speed over the 10 speed trans. The 10 speed is slightly wider fit, it to search more through the gears a lot more. The 6 speed has low first gear but 2 overdrive gears. - There are new front suspension systems which 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.
- Oil Filter Fitment Early 66-76 Bronco 66-77 Broncos use the existing oil filter housing with the cooler deleted often works. Keeping in mind there are many variations of frames, engine mount heights etc.. so each one seems to be different, but some will need a oil filter relocation kit which moves the filter to a remote location.
- Going with a pullout Junkyard Coyote may initially save $$ but drawbacks include cleaning up and deleting the OE wires harness and control pack not used. Reconfiguring the pulleys for fitment. Timing cover and Oil pan needs replacement The transmission from a mustang will not work for a 4 x 4 Bronco. Then of course a High mileage engine can pose their own risks.
- Most of these swaps use the Automatic transmission whether it’s the 4R70w, 6R80w or 10R80. The 4 speed will have the most room in the trans tunnel. The 6R80w with have little to no trans tunnel mods. The 10R80 Fits with more Trans Tunnel surgery. The 6 Speed is very popular being it has a tall 1st gear and 2 overdrive gears and easier fitment. The 10 speed has a tendency to search for gears, if doing a lot of highway use can be ok.
- Is there a better fit in the 66-77 Broncos whether that be the Gen 2 coyote vs the Gen 3 + 4 ?. The short answer is yes. We like using the new Gen 2 coyotes being they directly sync with the 6R80W without using an external controller . The factory oil pan fits in most early Broncos with a suspension lift. Otherwise the Gen 3 and 4 does with someGe
