Picking up a 67 mustang t5 conversion kit is probably the single greatest thing you can do for your traditional Ford in case you really plan on generating it. Let's be honest for a second: as much as we love the sound of a vintage small wedge screaming at higher RPMs, that elegance wears off pretty quickly when you're cruising down the particular interstate at seventy mph and your engine feels like it's about to vibrate through the floorboards.
The unique three-speed or four-speed Toploaders were tanks—nearly indestructible and excellent for the pull strip—but they weren't exactly designed along with modern highway rates of speed in mind. Back in 1967, the speed limit was lower, plus gas was inexpensive enough that no one cared about gas economy. Today, issues are a little bit different. If a person want to maintain traffic without burning a tank of gas every 50 miles, that 5th gear is a literal lifesaver.
Everything you Actually Get in the
When you start looking at a 67 mustang t5 conversion kit , you might be surprised just how much equipment is involved. It's not just a transmission swap; it's an organized upgrade of your own entire drivetrain interface. Most reputable products are designed to be "bolt-in, " meaning you shouldn't have to get out your torch and start cutting up your floor pans, which is the huge relief intended for anyone trying in order to keep up with the integrity associated with their car.
Usually, the kit includes a custom made crossmember. This is a big-deal because the particular T5 is shaped differently compared to older C4 automatic or the Toploader manual. Without the correct crossmember, the transmission won't sit with the correct position, and your pinion angle will become all messed upward, leading to a few nasty vibrations.
You'll furthermore see things such as a bellhousing adapter plate, a brand-new pilot bearing, and often a revised shifter handle. The particular cool thing about these kits is that they often let you keep the original stainless shifter handle so the interior still looks 100% period-correct. Nobody has to know you've got a modern five-speed under the boot until they help you shifting into overdrive on the freeway.
The wonder of the Overdrive Gear
The actual star of the particular show right here is the 0. 63 or zero. 68 overdrive percentage. If you're currently running a several. 00 or 3. 25 rear-end equipment, your engine is most likely spinning around a few, 000 RPM only to keep up along with a Honda Civic in the quick lane. It's high in volume, it's hot, and it's wearing out your internal elements faster than required.
Once a person install a 67 mustang t5 conversion kit , that REVOLTION PER MINUTE number drops considerably. You'll suddenly end up cruising at one, 800 or 2, 000 RPM. The car gets quieter, the particular temperature gauge stays a little reduced, and you may actually have got a conversation along with your passenger with no shouting. It becomes the Mustang from the "around-the-block" cruiser in to a legitimate long-distance road tripper. Plus, in the event that you've swapped in certain shorter gears in the back—say, 3. 55s or 3. 73s—the T5 gives a person the very best of both worlds: insane speed off the line plus a calm ride on the way home.
Dealing with the Clutch system and Linkage
One of the particular biggest hurdles people worry about may be the clutch. If your '67 was initially a computerized, you're going to need the entire pedal assembly, which many kits either include or provide as an accessory. If you're already managing a manual, a person have an option to make: stay with the old-school mechanical Z-bar addition or get a cable connection or hydraulic setup.
Personally, I think if you're already doing the particular work, a wire conversion or perhaps a hydraulic throwout bearing is usually the way to go. The mechanised linkages can be firm and vulnerable to binding, especially if you have long-tube headers that soak the Z-bar in heat. A contemporary 67 mustang t5 conversion kit often performs very nicely with a cable clutch system, giving you a pedal feel that's much closer to a contemporary car—smooth, light, and straightforward on your left leg in stop-and-go traffic.
Is It a "Driveway" Job?
I get requested this a lot. Are you able to do this particular on your back with a place of jack holds? Yeah, you can. It's not exactly a walk in the recreation area, but it's definitely doable for any weekend break warrior with a decent set of tools. The hardest part will be usually wrestling the particular old transmission out there and getting the new one aimed.
The '67 and '68 Mustangs have a somewhat wider transmission canal than the '65 and '66 models, which makes the T5 swap a little bit easier. You won't usually run into the clearance issues that the particular earlier cars possess. You might need to trim the tiny bit associated with the shifter starting in the flooring, but it's minimal.
A professional tip for anyone diving into this: inspect flywheel plus pressure plate whilst you're in presently there. It's incredibly luring to just bolt everything back collectively to save the few bucks, but there's nothing even worse than finishing the swap and realizing your old flywheel has a hairline crack or your clutch is slipping. Spend the additional money on a fresh clutch set while the transmission is already upon the floor.
Choosing the Best T5
Not all T5 transmissions are created equal. When you're shopping for your 67 mustang t5 conversion kit , you'll probably hear the word "World Class. " This doesn't mean this travelled the world; it's just a naming Ford used beginning in the mid-80s for transmissions along with better bearings and synchros.
If you're tugging a T5 away of a junkyard to use with your kit, make sure it's from a good 85-93 Mustang 5. 0. Those are usually the ones constructed to handle the torque of a V8. If you accidentally grab one particular out of a four-cylinder car or a different make entirely, the input shaft might not fit, or the gears may shred the first time you drop the hammer. Lots of people just opt for a brand-new T5 from an overall performance shop to avoid the headache associated with a mystery utilized gearbox.
The Difference You'll Experience on Day A single
The first time you take the car out after finishing the set up, the difference is immediate. It's not just about the extra gear; the T5 actually shifts very much better than the particular old Toploaders. The particular throw is smaller, the gates are more defined, plus it just feels crisp .
The '67 Mustang is a heavy car, using a five-speed, it feels lighter on the feet. You have more options with regard to staying in the powerband. On a twisty back road, it is possible to find the right gear to get a corner instead of being stuck among second and 3rd. It transforms the particular personality of the particular car from the brute-force muscle car directly into something that seems surprisingly refined.
Final Thoughts on the Investment
Let's be genuine: a 67 mustang t5 conversion kit isn't inexpensive. Between the kit itself, the transmission, and the assorted bits like gear oil and probably a new drive shaft, you're looking in a decent chunk associated with change. But a person have to look at it in terms of "smiles per gallon. "
If your Mustang currently sits within the garage because it's a pain in order to drive on the road, then it's not really doing its job. This particular swap changes that will. It makes the car usable. It can make you wish to take the long way house. Whether you're going to a local car show or planning a cross-country travel, having that fifth gear helps to make the difference in the world.
From the end of the day, we all own these cars to drive all of them. Something that makes the driving experience better—without ruining the traditional soul from the machine—is a win in my book. The T5 swap is the gold standard for a reason: it just works. Stop overthinking the RPMs and just get the kit. Your ears (and your engine) may thank you.
