All Six Load o matic

[EddieSystematic]

Hi - I am new to the inline 6 ford engines, and I hope someone can answer a few questions. Vehicle 1967 Mustang inline six
How do I determine if I have a load o matic distributor? It is an auto lite distributor with the number c8ui 1227 bh stamped on it and I can't cross-reference the numbers.
the vacuum advance has a threaded end on it

second question is how I determine CI displacement I have 5 freeze-plugs and 4 bolts on the water pump I can't be certain there are 4 but I think so.

casting number points to a 1978-1980 block
16 D8BE 6015 (block)
Of23 14 EOBE-6090-BB (HEAD)
I went down a few rabbit holes looking for the info, judging by the shape of the valve cover and the number of freeze plugs, I believe it is a 250
Any help would be appreciated

If you pull the cap on the distributor, try to turn the rotor by hand in the direction of normal rotation; if you can turn it a few degrees with light to moderate pressure it is not a load-o-matic. If you can't turn it; most likely then it's a load--matic.

Hi, the 250 has a 4 bolt water pump. All of the other sixes have a 3 bolt pump. The LOL has a thin pancake style vacuum advance canister. The later distributors have a cone shaped vacuum advance canister. The distributors will interchange on all but the earliest engines. What car do you have? We have a tech section with all the information about these engines. Good luck
