We just finished a valve job on my ”˜41 special deluxe. While the head was at the machine shop I ordered a gasket set, FS 181 from Filling Station. When it arrived we found that the holes in the head gasket didn’t match the bolt holes in the block. We ordered a gasket set from NAPA, FPG HS7276B, and the head gasket fit. The Filling Station gasket was to fit ”˜37 to ”˜53 216 and ”˜41 to ”˜49 truck 235. What’s the deal? My head has the word Canada on it. My block has the number 48 with a circle around it. Is my block Canadian? The car was built in Canada. Are Canadian engines different? Why would NAPA’s gasket fit? Thanks, Sid

Did you contact the Filling Station about the problem?

In Canada they were still using the dome piston design in 1941. However that should not affect the head gasket.


My 1951 1 Ton is now on the road! My 38 Master 4 Door is also now on the road .

The filling Station agreed to let me return them. I advised them that the head was Canadian, but I was not told that was why it didn’t fit.

From mid year 1951 and up the Canadian 216 used a block derived from a 235 low side cover engine......what is the engine and casting numbers on the block?
That engine would not use a US 216 head gasket but rather a 1950-1952 235 head gasket.
I do not know the application for the NAPA numbers you listed.

The circle with 48 would indicate a '48/'49 block. At least in the U. S..[Linked Image from pic100.picturetrail.com]

The car is at a friend’s shop where we are dealing with the horn issue discussed in another post. I’ll get the numbers in a day or two. Thanks, Sid

We found this number 265117 stamped on the side of the block aft of the distributor. I didn’t think about a casting number. Is It on the bell housing like a V8? Thanks, Sid

The casting should be embossed right under that circle with the 48 in it. You can see it in the above pic. Right behind the vac. line.

Does not match any U. S. numbers that I can find.

If you can get behind the starter, You will find the date it was cast.

That is a Canadian casting number. I can not find what year or if it is a 216 or 235.
I woul guess it is from the mid to late 1950's.

This engine looks like a 216. Its valve cover is held down by two acorn nuts, and it has a full size side plate requiring cork rings to seal around each spark plug. Would it have insert bearings or babbit? Thanks for the help guys. I’ll look for the number behind the starter. Sid

If it has the little stamped metal held on with three screws on the left side of the block kind of behind the exhause pipe is has oil dippers on the rods and no inserts (unless it was rebuilt at one time)
Will also hve 15 pounds of oil pressure at about 2000 RPM.

In the US 1948 and 1949 engines had the raised circle with a 48 in the center.....could be a 1948-49 Canadian engine. If that is true the 1937-1951 Canadian 216 used the same head gasket as a US 216.
There will be no number behind the strater.

My mechanic friend replaced the rear main seal in this engine a few months ago and remembered seeing the dippers on the rods and troughs in the pan. So, it is a Babbitt bearing engine. I didn’t find a casting number near the starter. I presume the block is Canadian as well as the head. But, why would NAPA’s head gasket fit and filling station’s would not?
