Pre-fix for Canadian part #s

[russcc]

What is the Canadian part # pre-fix for the aluminum 6520 intake manifold. Doing a search here on Fordbarn for one. Thank you.

The basic part number of 6520 is the same for all V8 intake manifolds of the flathead era and beyond, be they cast of aluminum or iron. What distinguishes the individual manifolds are the prefix and suffix added to the basic part number. Generally, a unique Canadian version or in some instances where even a non-unique version sourced in Canada will have the letter C added to the end of the prefix such as 18C, 40C, 48C, 78C, etc.

Thank you. I was pretty sure there were pre-fix letters before the 6520 basic part number like 59T-6520. So would the number look something like this 8BA-6520-C ?

I have an aluminum Canadian Merc manifold on my car; I will check it this afternoon.

With utmost respect David, The 'C' is the prefix as in C8CM 6520 cover-valve chamber [used from serial #H48-20000] pass, Mercury and Monarch 49.
The above is a direct quote from the Canadian 'Fast Moving parts Catalogue 1928-1949'.
And yes, that is how they spell catalogue!

Is there a suitable single 2 barrel aluminum manifold for the 59 series, like the Canadian Ford ones or aftermarket. I don't want to get into 8BA conversion issues for the 59 engine.

The C at the beginning is a normal "Canadian Made" part of their prefix system but how much it was used is unknown to me since I don't have any Canadian parts catalogs. The C at the end of the prefix is usually a designation for Commercial vehicles or light pickups.

Any letters or combination of letters in the suffix at the end of the part number refers to engineering changes only. It would not reflect the origin of the part but only changes made to that part.

Most folks look for the Canadian cylinder heads since a lot of them were aluminum but not as many for intake manifolds due to the heat riser set up being a heat corrosion problem area on some. A person might be better off with an aluminum 4 barrel carb manifold using an adapter plate.

Is this the one you're referring to? It's the C11A-6520 Canadian intake with the oil-fill at the front, right. A friend from Wisconsin sent me this one NOS several years ago. DD

Sorry about that; while I did not look at one of my Canadian parts catalogues before writing the above, I did go to one of my drawers where I have several different Canadian parts in their original boxes and the C is at the end of the prefix and the parts are not for commercial application. Next time I will look at the catalog before leaping, but my eyesight is not failing with regard to those box part numbers. Likely they are misprints, but it is a bit unusual to find them on the boxes of unrelated parts.

rotorwrench, With respect, a number following a letter in a suffix does indeed reflect the origin of the part in terms of either its design or it being from an outside source.

[russcc]

Origin of the parts aside. Anyone know a source for an adapter plate to convert a 4 barrel manifold to a standard Ford type 2 barrel like a 94 or 97. This is for my test stand to run the 59L I just finished. I have an Offy 4 barrel manifold I will be running on the engine when it graduates from the test stand, so that would be the ideal way to do it.

Here is a couple numbers off my Canadian 8BA.
