Before we install the 400+hp Ford 5.0L Coyote motor in the Bondurant Cobra, we wanted to go over a few of the key pieces that are required to do a Mustang Coyote Swap in a Fox Body or SN-95 Mustang. There were a few modifications that were required to install some of these parts. Follow along in the video as Jmac shows you what parts are needed and what modifications were required before we installed the Coyote engine.
The first major component you will need to look into is a Mustang tubular k member
. If you have a 96-04 Mustang, you can use your factory k member. Because our Bondurant Cobra’s suspension was built around the stock k member, we decided it was best to keep the stock k member. We encountered some clearance issues with the k member and the long tube headers. Jmac will point these out in the video. With a little mild modification to the header tube (hammering in some slight clearance), the BBK Coyote Swap headers cleared just fine. We recommend using the tubular k member to gain more clearance in your engine bay as-well-as you get the benefit of dropping a few pounds off the front end of your Mustang! If you have a 1979-95 Mustang that came with the push rod 5.0L engine, you have to use a k member designed for 4.6L mod motor.
Next up on our list was oil pan clearance. The stock Ford 5.0L Coyote oil pan would not clear the Cobra stock k member without being modified and cut up. To avoid trying to figure out exactly what needs to be cut and added, you will need to use a Coyote swap oil pan to properly clear your 79-04 k member. For this, we turned to Moroso and used their Mustang Coyote Swap Oil Pan
. The oil pan will not clear the BBK long tube headers, so we made a quick trip to a local fab shop ans we were back in business! Modifications can be seen in the video.
Next up, we addressed the transmission installation. We saw no reason not to re-use a good functioning transmission, so we decided to reuse the Tremec 3550 transmission that was previously in the Bondurant Cobra. To accomplish this task we used a Quick Time Bellhousing (RM-6081)
. This SFI approved bellhousing came with all the needed hardware: Bell-housing, spacer plate, pivot ball, fork brackets, grade 8 hardware and install instructions. Since this bellhousing was designed for 4.6L/5.4L Ford modular motors, there was some modification needed to install this bellhousing. The spacer plate and dowel pins were both modified to for clearance – refer back to the video to see the what modifications are necessary. We used a 96-04 4.6L Mustang 8 bolt flywheel and clutch assembly to finish off the transmission set up.
The final piece we had to address before installing the motor was an important one – how to mount the coyote motor to the k member? Luckily this is much easier than it sounds. You can simply take 96-04 4.6L Mustang motor mounts
, bolt them right up to the Coyote motor and you’re done. No modifications needed here!!! With all of these steps complete, we can now turn our focus on installing the Coyote into its new home. Stay tuned… it is about to get fun!!
