I realize that. My question was whether the same slot length in the MP Mallory units and factory units (after welding and filing) results in the same amount of advance.
Mopar Performance Distributor adjustable advance?

Just ask whatever you ain't gettin and we'll do our bestest to help you understand. The red keys for example. Each one is a different thickness. You loosen the advance screw on the breaker plate on those distributors and use the keys to stick in the slot to give you "whatever" advance you're looking for. The length of that slot controls how much advance you get. Bigger slot = more advance.
Oh ok. Now THAT I don't know, but I would just bet not, since they are completely different designs.
Any time you need help with this stuff, the call is free, LOL
The weld it up slot lengths for the winged plates on old style/OEM are different

Of course they are. Because if they were the same, that'd be too easy.

Thank you for all your replies! I was already looking for a new distributor not knowing that the one I had was actually a really good one.
Thank you, I always appreciate learning how it's done correctly!
I did find the tuning keys on ebay and they even come with springs. I also ordered a new reluctor because the one in the distributor is pretty chewed up.

You're certainly welcome and remember, if you get hung up on something, don't be bashful. Just ask. We can walk you right through it.
Just the non adjustable ones with a fixed slot on the advance cam
So, the purple chart does not apply to the op's distributor? @abodyjoe @halifaxhops
Probably not......but it "might". I don't know of anyone who has ever compared.

You will likely not be able to buy springs to control that advance mechanism. You can’t get a spring that is stiff enough.
I had new weights made just for these distributors so that I can do some testing and see if i can change the weight and shape of the weights to get a better curve.
Depending on your engine you may be able to get a reasonable curve with what you have.

The purple chart is for the OEM distributor wing plate slots.

correct
Someone commented that you should toss in the nearest garbage can. I'd add, buy an MSD distributor. They have the advance springs on top, instead of underneath. Setting your advance is a piece of cake.I got one of those FBO limiter plates and was about to set it in the distributor, when I noticed two things. At first I noticed that the reluctor was a bit unevenly worn and the pick-up wasn't parallel to it. I'm sure that can't be good.
Upon closer inspection it looks like the plate is bent. I think I can bend that back.
I noticed that the FBO limiter plate is not going to work, but that the adjustment can be done with an allen wrench?! I don't know for sure that this is a Mopar Performance distributor and there is no part number on it, but when I looked at photos of MP distributors, they look just like it. Anyways, what I like about the FBO plate was that you could set your initial and then set total based on that number plus whatever added up to 34. My initial was 22, so I was going to use the #12 slot. I wish I had opened that distributor before I ordered the plate and the springs, which I don't think will work either. Anyways, any idea how I can set this up without having to take it out again 15 times?
