From the mating surface to the bottom of the gear the measurement is the same, however from the bottom of the gear to the end of the shaft, the new distributor is about 1/8 of an inch shorter. Do you think this will engage far enough with the oil pump drive shaft??? Cardone vs Loadomatic. Thanks
My new distributor 55 F100

When you look down into the hole for the distributor you can see the machined surface the 'driven' dist shaft gear spins on. (photo 2) How much of the oil pump drive shaft sticks up into the hole in the middle of it? That's how much engagement you'll have.
It's a very common problem with the cardone replacement distributors, because they're not using original Y-block style parts.

Also, do not use a gasket between the shoulder of the distributor housing and the edge of the hole at the top of the block. It will raise the distributor even more.
But the bigger problem with having a gasket there is the rotation of the cam tries to pull the distributor shaft farther down into the block, since the driven gear will be the gasket thickness above the surface it should be spinning against. This will cause serious damage to the upper surface of the dist shaft bushings and can eventually ruin the dist housing.
I would have measured the height of the oil pump shaft in the block in photo 2 above so you'd have something to compare yours to, but it doesn't have the shaft or oil pump.

Next can of worms... 
In a previous thread a photo of the cardone distributor shows it may be something close to a '60 / '64 style.
Ford changed the originals between '56 and '57... '56 was the last year for Loadomatics.
The cardone dist you're wanting to use would be spec'd for '57 and newer, they don't work the same internally as the earlier ones. (but it may be slightly 'better' in the long run???)
Maybe you still have the '55 distributor you took out?
Does the engine still have the original '55 carburetor on it? Which one is it?
The original vacuum timing advance canisters are vacuum pressure matched to the same year range carburetors... '56 & earlier, or '57 and later.
Did I miss something, why are you changing the distributor?

I originally was replacing the loadomatic, because I didn't see any vacuum port on my Ford 2100 carb, so I wouldn't have any advance. A mud dobber later I discovered a plugged vacuum port above the throttle plates. So, I plan on using my original Loadomatic. If the new Cardone will work, I will just keep it as a rainy day spare. Not original carb as noted. What do you think?

Does the 2100 carb fit on the intake manifold? Unless it's been changed I believe '55 originally used a different style carb and bolt pattern for it.
Barring other problems the 2100 carb and the cardone distributor should work together. They're both newer than '57, so the vacuum timing advance is compatible. The newer style distributor relies mostly on mechanical timing advance anyway. The old loadomatics have no mechanical timing advance at all.

Yes, different manifold and carb..Thanks for the info, getting closer.
