no clearance issues at all with the firewall. It fits under the factory screen.
I received my Progression Ignition distributor and there is a problem with the size, it is slightly too high, not only does it not fit under the cover but one of the spark plug wires touches the mounting rail. Have you had this problem?
It is the part # SC0531

Did you order the Male (HEI) or Female cap? The Male cap does not fit under the screen. I am running the Male cap on my 74 Euro Pantera and it does not have a screen but it clears the firewall and does not misfire. With a Female cap, we put it into a customer car and it fit under the screen. The cap is a standard GM/Chevy cap and it is readily available in the US at Autozone in either form for not much. It might be harder to get in France.
Here is a photo that I just snapped of mine with the Male HEI cap.

Also, I do not get cross fire of plug wires on this car. My other Pantera with the very large MSD coil cross fired a lot and I had to carefully separate the plug wires, particularly on the passenger side where the coolant tank and tube gets in the way.
For what it is worth, the "Motorcraft" solid state distributor with a male cap fits on my car with the screen.
IF that is the criteria buyers are looking for on their Panteras details like that should be known in advance?
Not everything out there made for a 351c is going to be directly applicable to a Pantera. It is a very "unique situation". Even how you route the spark plug wires and the type that you use has special application.
I chose a female cap.
What bothers me much more than the height is that it touches the firewall rail in which the cover is housed. With the movements of the engine it can't resist for long.
Even if they are higher, do you know if the male caps have a different diameter at the level of the spark plug wire fixing pins, in the photos they seem to be slightly smaller.
I wonder if Progression Ignition has not modified its distributor since you bought yours to use a higher one.
In any case they don't manufacture them, I think they just mount their electronics in distributors that they buy from others, maybe MSD, otherwise why would they have the upper plate where the weights are usually installed?
I know that not everything that is installed on the 351C is suitable for the Pantera but there I was confident since you had already done it and Wylkinson installs them.
I don't necessarily find comfort in using Wilkinson as a guide. He has his own purposes in mind.
If you are asking me about the cap on my Motorcraft, the male cap is not for a Ford. The original application of the cap is for an International Harvester 350 v-8.
Without measuring anything, I would say that the male cap is made from a modified mold for the female terminals cap.
The centerlines of the individual terminals are the same as is the external outside dimensions of the female cap.
The difference is that the spark plug wire boots for the male terminals are smaller in diameter then the female boots are and that is where the clearance comes from.
I also have 1-1/2" thick foam sheets covered with mill polished stainless steel sheetmetal panels on the firewall so that closes down some of the clearance space.
Again without measuring, it must be that the "Ford" distributor is not as tall as the aftermarket versions? That is the only specification that would effect this issue substantially enough to cause clearance issues to the cap and the spark plug wire boots?
I'm thinking that the features of the Progression distributor are a great idea but also that for a Pantera, the internal device should be built into a Ford distributor?
In a previous post, Bosswrench mentioned that the Pantera drivetrain can be moved back up to about 1-1/2" to gain more firewall clearance without issue to the u-joints on the transmission.
We have a another engine at the shop that is going into a car soon and it has this ignition with a female cap. That will be the third one. We just ordered it. I will try to compare its dimensions to mine.
I will also try to get a sense if the tall cap is narrower.
You can see in my photo that it is not jammed against the firewall. I am wondering if your engine is sitting up and forward. I will be at the shop tomorrow and ask Steve about it.
I think you can send an email to Progression Ignition and ask if housing changed.
It looks like my setup has a lot more room than yours based on these new photos I just took.

Steve,
What would be helpful (and greatly appreciated!!) is a side-by-side photo and dimensional comparison of the Progression vs the stock Motorcraft distributors.
John
I will try for that tomorrow.
I positioned the engine as far back as possible without modifying the supports but by putting the two large shim washers on the same side in front of the ZF ears.
I cut and twisted the two lips of the cover sheet metal fixing rail and it no longer touches.
I will cut the cover sheet metal a little to let the cap pass, I have already done it to let the air filter pass and as it is behind it will not be seen.

Wilkinson is suspect that you have the motor mounts reverse. They are not symmetrical. Here’s a photo of the two caps. The Autolite cap is just slightly smaller diameter maybe an 8th inch.

Hi Steve,
I may have asked this in a different thread but don't believe I got the answer.
How can you tell the difference between left and right motor mounts? It appears that this could move the engine forward or backwards up to about an inch.
Thanks,
John

In my mind, the engine position is determined by the ZF mounts and if you swap the engine mounts, you can't install the mounting screws.
But I could be wrong and I'd be happy if someone could explain how to move the engine/transmission assembly back without changing the transmission mounting points on the chassis.
Back to the Progression Ignition distributor, the one I received is significantly longer than the one in the 2021 lf-tp2511 photo at the beginning of this thread. So I'm pretty sure the housing has changed.
By the way, I finished installing mine and the engine works.

This posting describes the the engine mount differences from side to side and their offsets.

Glad your engine is running with the new distributor.
Can you post a photo of your transmission mounts. It would help to see where the shim washers are positioned relative to the insulators.
In case you have not seen it, please see this posting:

Tuesday was busy at the shop. On Wednesday I will try to measure the length of the Progression Ignition distributor along with the factory Autolite unit.
No, I do have the two side supports, I'll take a picture tomorrow.
The post about moving the engine is interesting but I'm afraid it's not so easy to deform the two rear sheet metal supports. In addition, the air conditioning condenser housing must be modified so that the ZF rear cover mounting nuts don't hit it.
But I admit that if I had had this information earlier, I would have probably studied it closely. But if one day I have the time .........
I took a photo of the Progression Ignition and Autolite side by side today. The Progression is now about as tall as an MSD, too tall to fit under an engine screen. Their previous version's height was similar to the Autolite.

I haven't installed my Progresson dist with male cap but it is exactly the same heiigrh as the MSD8350 ready to run dist.
