FYI Ford, Classic Mustang Tech Discussion » Fourth water pump in my 69 » 6/14/2025 3:22 PM |
My March setup uses a standard stock style reverse rotation pump and will work with a mechanical fan. Clearance could be an issue if your current pump is much shorter than a stock 91. Not trying to spend your money but it might be an alternative. I have heard that the aluminum water pump pulley will likely wear over time but it looks brand new so far. I installed a stock heavy duty (HO with A/C) fan and an oddball clutch off of a jeep because I needed the 1/4" shorter unit to clear my radiator properly. I have the mid-mount A/C compressor on the passenger side. There's no easy way to revert to V-belts on my setup but if that isn't a problem with your setup, V-belts may be a better solution.

There should be a fuel pressure port on the fuel rail. Rent a pressure gauge at Autozone and see what you have. Check specs for your particular engine - Ford used different pressures over the years. It is not unusual to see some drop in pressure after the initial pump prime so try to measure during the pump prime cycle. It might take two people. A clogged filter will often build pressure during prime and might even let it idle. A no-start would tend to point to the pump.
FYI Ford, Classic Mustang Tech Discussion » What transmission? » 5/28/2025 8:30 PM |
If you don't have any long road trips planned, a C4 would work well, keep costs low, and be fun to drive. If your rear gear isn't right for the C4, you could do the C4 and a new gear and still be money ahead over the OD options. The 4R70W is a much better trans than the AOD and that's what I'd install if I needed/wanted OD.
FYI Ford, Classic Mustang Tech Discussion » Tri-Y headers » 5/23/2025 8:43 AM |
I used Doug's long tube headers in my 66 and have heard good feedback on Doug's tri-y's. The full length fit well with no mods but I'm running borgesson PS and a hydraulic clutch on a TKO. They offer an automatic or stick version in the tri-y's. They used to have painted steel but now it looks like ceramic coating is the low-end version. Feedback on Doug Thorley headers (his wife won that in the divorce) are mixed at best.
FPA can build you a set for a price but they also likely have the highest probability of fitting.

FYI Ford, Classic Mustang Tech Discussion » Lower Radiator Hose » 4/16/2025 5:57 PM |
I cut 1" off the engine side of the 20609 and 1/2" off the radiator side and I have a perfect lower hose for the 302 turbo engine in the 46 Ford project I'm building for a friend. The Ranger hose fits perfectly for the upper. Finally a 2 steps forward and only 1 step back day.
FYI Ford, Classic Mustang Tech Discussion » Lower Radiator Hose » 4/11/2025 3:57 PM |
Gant or Gates? I ordered the Gates 20609 from Rock Auto today and can't find the Gant part.
FYI Ford, Classic Mustang Tech Discussion » Lower Radiator Hose » 4/11/2025 8:24 AM |
I went out and checked the lower hose I referenced above. I had only checked it for shape and sure enough it fits the shape but I also need 1.75 on both ends. In order of trial and error I'm going to try this first -
=13px which is a 1970 302/351 lower
And I'm next going to try hopefully a lower cost version of this - Maverick 6 cylinder 1970 -
Both of these are 1.75". The Gates is molded but is listed as cut to fit for the Mustang. The big block options are 2-1/16 on one end so too big.
FYI Ford, Classic Mustang Tech Discussion » Lower Radiator Hose » 4/10/2025 8:37 PM |
For a driver's side lower radiator hose I have used the lower hose from a 1970 Mustang or Maverick with a 302.
Since I'm using a serpentine setup (same as a 5.0 swap) I use a 90 degree thermostat housing and the lower hose from a 1986 Bronco II 6 cylinder manual for the upper. I had to trim one end about 2" and it fits perfect.
I found the hoses here in post 5 - =13px
FYI Ford, Classic Mustang Tech Discussion » Has anyone put a vaccum cannister on their car or maybe a vaccum pump » 3/10/2025 8:56 AM |
On a current project - a turbo SBF in a 46 Ford - I picked up two Volvo turbo car pumps/check valves/sensor-switches. There are a number of how-to's you can find with searches on how to plumb these in. The pump only operates when vacuum is low on the brake booster side. Under turbo boost the check valve prevents pressure from entering the brake booster but if there is sufficient vacuum already the pump won't run. In a N/A application, it will simply sense vacuum on the booster side and if it dips, the pump will activate. I'm going to trigger a relay with the Holley EFI so that the pump will only run when the engine is running. If this wasn't an underfloor brake setup I would have installed a Hydroboost.
Here's a pretty good overview - =13px
On my 66 I installed a Hydroboost as part of the build since I knew I would have low vacuum and I needed the space. I always have good brake pressure regardless of what the engine is doing.
But, I'd use a vacuum gauge first and see if a combination of idle speed, idle mixture, and timing can improve your idle vacuum.

Camera stick use aside, if you're ambitious you could build a set of Caltrac clones -
One of negatives on the Drake bars is the single shear bolt setup. However, breakage is probably related to HP, traction, and excessive use.
FYI Ford, Classic Mustang Tech Discussion » Setting the pinion angle price » 2/28/2025 10:00 AM |
Is there anything unique about your engine mounts or trans crossmember/mount? Compare your angle readings with your phone as a double-check.
FYI Ford, Classic Mustang Tech Discussion » Setting the pinion angle price » 2/28/2025 8:49 AM |
Right eye on March 18 left eye on the 25th. Still won't correct looking at the arrow on an angle finder the wrong way.
FYI Ford, Classic Mustang Tech Discussion » Setting the pinion angle price » 2/27/2025 8:09 PM |
The angle finder shows one thing and my eyes seem to see the opposite. It could be the angle of the picture/camera. You may want to pull the driveshaft and measure off of the yoke to be sure. And - try another angle finder or use your phone - as mentioned there are a lot of apps and you'll get pretty accurate digital values.
If it is up, a 3 degree wedge could bring it down to about 2 degrees Why I am suspicious of your angle finder is that at RPM mentioned, your engine/driveline should be lower in back. A common setup would be about 3 degrees down on the drivetrain and the pinion flange "up" about 2 degrees to account for the wrap of the leaf spring when under load. Sorry for the confusion on my part with the numbers. I'll blame it on the cataracts/
FYI Ford, Classic Mustang Tech Discussion » Setting the pinion angle price » 2/27/2025 6:32 PM |
Did you install the spring perches or did they ship the new axle to you with the perches welded on? Is the axle sitting properly on the springs? Is the car on the ground at ride height or is the axle hanging down?
if the pinion flange is indeed 5 degrees down it is way off, I'm not sure I trust your reading on the trans. You might also confirm with a reading taken along a valve cover with the level held level side to side. Or, you can also try to get a reading off of the crank pulley. It looks like you may need a 4 degree angle/wedge shim to bring the pinion flange "up" but I'd try to figure out why it is sitting so low in the first place.
Report back what you get on a valve cover or some other point on the engine. Don't use the air cleaner or carb flange as they are usually angled at about 3 degrees so the carb will sit level when the engine angles down. Are you running stock-style engine mounts? Do you have an aftermarket trans mount? Do you have big tires in back that is angling the car down in front?
You can't run it like that. You may be able to find a driveline shop that does driveline setups rather than a generic chassis shop. And, Is your driveshaft the correct length? If it is too long it could be forcing the pinion down.
FYI Ford, Classic Mustang Tech Discussion » Install Convert Seat Platform into Coupe » 2/25/2025 9:38 AM |
I don't believe the platform alone will do much. It is designed to install with convertible inner rockers and also works in conjunction with these
You would also add the convertible plate that bolts the two supports together.
The convertible platform also raises your seats up which can create some clearance issues.
So, you can install one but I'm not sure what you'd gain. A good set of weld-in subframe connectors and torque boxes on both sides might be a better choice.

All of the parts can be found at Rockauto.com or other site like Summit. I trust these over many Ebay sites.
If the instructions and parts list provided (which includes model years), contact the MustangSteve crew
So, to further clarify - order the bracket kit from MustangSteve.com, use the instructions to determine the parts you'll need, order the parts, and put it together.
FYI Ford, Classic Mustang Tech Discussion » Setting the pinion angle price » 2/16/2025 5:52 PM |
To clarify, is the nose of the pinion pointing up or down? Not sure I've seen many applications where the back of the transmission is higher than the crank at the front of the engine. In a lot of stock-ish applications the engine will be down in back 2 or 3 degrees So, when you talk up and down, if you were standing on the drivers side of the car facing the door, is the front of the engine higher or lower than the back of the transmission? Is the pinion flange pointed up or down?
FYI Ford, Classic Mustang Tech Discussion » Setting the pinion angle price » 2/16/2025 9:00 AM |
It is easy to measure your engine/driveline angle and your current pinion angle. There are even apps on phones to let you do it. Measure first and determine if you even need the angle changed. There are a lot of variables - spring type, suspension type (link versus leaf), etc., but if the pinion is 1 or 1.5 degrees "down" from the engine it will load up and be right where you need it. Leaf spring shims are readily available to raise it up or down and are easily installed with a helper if needed.
Why do you think you have driveline angle issue? Are you fighting a vibration problem? Are you confident that the pinion angle is responsible?
At a minimum I would measure it yourself rather than taking it to a shop with an open checkbook.

FYI Ford, Classic Mustang Tech Discussion » Reverse rotation clutch fan » 2/01/2025 10:19 AM |
I have an early 90's Hayden reverse rotation fan clutch new in the box. I used it to mock up my setup and it was too long due to my thick radiator. I found a shorter duplicate using this -
Send me a message if you'd like the clutch. it's yours if you cover shipping.
For a project on a 1946 Ford I bought a Advance Auto Parts pump for a 93 GT. It has round ports so it will work on either a normal or reverse rotation timing cover.
FYI Ford, Classic Mustang Tech Discussion » Reverse rotation clutch fan » 1/24/2025 9:06 AM |
Do you have a part number for the kit? March has fairly good descriptions of parts requirements and what fits on its web site. Some will and some won't support a mechanical fuel pump based on the part number and the type of power steering pump that it supports.
FYI Ford, Classic Mustang Tech Discussion » Transmission Leak C-4 » 12/28/2024 6:32 PM |
Glad it worked for you. Did you put it in the outlet or return line of the cooler? I think that over the years, parts from different transmissions may have been used and check valve function was lost. Easy fix and for many older transmissions I would probably use one any time I did a swap or rebuild.
FYI Ford, Classic Mustang Tech Discussion » 302 - ENGINE TROUBLES » 11/26/2024 5:30 PM |
Depending on moon phases and sun spot activity, a clear fuel filter will not always be full of fuel when the engine is running. There is enough fuel flow to keep it running, which isn't much at idle. When the engine had the same symptoms with two different methods of fuel delivery and a multitude of new parts, it likely had to be something else. When a distributor module flakes out, it won't cause the engine to slow down so much that the filter won't be full - it'll quit. I bet that the fuel filter still doesn't always appear to be full now that the ignition module is fixed. A number of MSD systems will also fail in the same manner - run for 30 minutes and quit and then restart after an hour - until they eventually quit altogether. I'd make sure that the Mallory setup is getting the proper voltage for that particular model. Some require straight battery voltage with no ballast and some require a ballast resistor to keep them happy. A timing light is helpful. If it quits, either grab the coil wire or even better hook up a timing light. If the light doesn't flash while cranking, the ignition quit.
