Does anyone know what a flat head 6cyl 23 inch engine with the #N48331 is from? It is in a 1935 Dodge Sedan built in Canada. Did they have different #s for the Canadian Dodges?

Sounds like a number that a rebuilt engine would have.

most, but not all of the Chrysler products that came to New Zealand were Canadian assembled and there engine #s were the same as the US built ones .

35 Dodge engine serial numbers should start with "DU"

Generally speaking the system was C=Chrysler, S= DeSoto, D = Dodge, P = Plymouth, T= truck, IND = industrial. Not sure what the tractor and marine engines had.
After they stopped putting them in cars, the flatheads used in trucks had a different system. 2 figures and a letter. 23A would indicate a 230.

Chrysler Canada did not have their own engine plant until 1937. So your engine would have been made in the US if it is the original block.

For a Canadan-built 1935 Dodge, if it is the American-style DU the would have prefix DU. But the smaller Plymouth-based DV and DV DeLuxe used Plymouth engines and thus would have prefix PJ.

When the Canadian engine plant opened early in the 1938 model year, the small Canadian Dodges adopted prefix D9 (Six) and D10 (DeLuxe Six) while the big Dodge (Custom Six) kept the D8 prefix. All Canadian-built engines had a`C`in the number.

So in Canadian built vehicles they still used the same engine #ing system as in the US. But why did they use a different body # system? The Body # on the tag screwed to the right front door post is 94 045 18 316 DU4DR'SDN. I would attach a photo but can't figure out how!

Generally marine engines have an M prefix. I don't know about tractors and farm equipment.

Do you know anything about the 51 thru 58 Chrysler, Dodge and DeSoto V8 hemis and polys. Were any made in Canada? A while back Rusty O'Toole told me he though the only V8 made in Canada at that time was the 277, 305, 318 used in 55 thru 58 Plymouths and Dodges. Can you add anything to that?

That "Body #" tag is actually your serial number along with the model, body style and body number.

9404518 is the serial number, which ran from 9403286 to 9405679 - a total of 2,394 built. Yours is the 1,233rd DU built in Canada.

"DU 4DR'SDN" -
DU - Custom Six (as it was known in Canada)
4DR'SDN - body style - 4-door sedan

The "318" was for the body number (318th DU 4-door sedan built)

This tag is a little different from most I have seen on Canadian cars of this era. The tag on the right front hinge pillar had just the serial number while there was a separate tag with the model, body style, body number, trim and paint codes attached to the cowl.

The Canadian plant imported blocks from the U.S. (not sure if short blocks or with heads) and added Canadian-made intake and exhaust manifolds, stamped items such as valve covers and oil pan, rubber, electrical and ignition parts and carburetors. This was done for 1951 to 1957 Chrysler V8 engines, 1952-56 DeSoto V8 engines, 1953-55 Dodge V8 engines and 1955 Plymouth V8 engines. All these imported blocks were given Canadian engine numbers that ended with a "C".

Chrysler of Canada opened a new V8 engine plant for the 1956 model year. First off the line came the 303 V8 engine used in the Custom Royal and Windsor. After using up the last of the 270-cid blocks, the plant started building 277-cid engines for Plymouth and Dodge.

For 1957 the engines were the 303 for Plymouth and Dodge along with the 313 for the Custom Royal. The Canadian 1957 Windsor used the 354 poly while no DeSotos were built in Canada for the 1957 model year. Instead the Firedome and Fireflite were imported.

1958 had the 313 V8 used on Plymouth and Dodge while the Canadian-built Custom Royal, Firedome and Windsor used the 354 poly. In 1958 all Imperials, Chrysler New Yorker/300-D, DeSoto Fireflite, convertibles, and Sierra/Windsor wagons were imported. As always, the imported models were identical to the models sold in the U.S. No Coronet, Royal, Firedome or Saratoga models in Canada - although the 1957-58 Canadian Windsor was actually the Saratoga with Windsor nameplates.

The B block V8 engine went into production in Canada for 1959, with the 361 used in the Custom Royal and Windsor while the 383 was used in the Firedome and Saratoga. No RB engines were built in Canada until 1963 when the New Yorker once again rolled off the Canadian assembly line. 1963 was also the first year since 1936 for a Canadian-built Chryco convertible.

The 313 remained in production through 1964 and was replaced by the 318 for 1965.
