9X 3157 sounds like a typical rebuilder's code; definitely not a factory code.

Sounds like a 1965 block.  What is the casting number?

I believe the 3782870 is his block casting number...  (from the subject line)...

Thanks gentlemen!
 Back in '65, were Canadian blocks suffix-coded any differently than U.S. blocks?
Could Rochester  7025131 and intake 3866922 dated A9 5 be good on this block - date-wise?

All engines were built in Tonawanda, NY or Flint, MI as far as I know.. no difference for Canadian (although, there was an old wives tale?? back in the sixties that late 50's (1959 283) blocks had thicker water jackets than otherwise, but have no idea if this was true, or for what reason if it was..?)

Block:     3782870   1962-1967        327     car & Truck 2-bolt  (date B 4 5    - Feb 4, 1965)
Intake:    3866922   1962-1965      283/327     4-Brl WCFB           (date A 9 5 - Jan 9, 1965 could be original to the block)
Carb:       7025131       1975-1979                   Rochester QJ         

(QJ Not original to the block or intake - in fact, has a different throat than wcfb and without an adapter wouldn't work on intake)

If you mean McKinnon-built engines, no - the only difference was the first character (it was a "K" instead of "F" or "T").

OK John, you've taught me something new again.. Smiley   Until now, I've known *nothing* about a Canadian engine foundry for Chevy.  What years were Chevy engines built at McKinnon?  I've never seen an engine so marked... (perhaps because I've always lived in the southern US, and never seen a Canadian built 'old' Chevy)...  but being the curious sort, I did a little search and found several references to the McKinnon plant, and this entry on 'GM plants', which had quite a bit of detail on McKinnon Industries.
 
http://canadianponcho.activeboard.com/index.spark?p=3&topicID=37134625&page=1&sort=newestFirst

Incidentally, for those of you as unfamiliar as I was on McKinnon, it is located in the St Catherines, ON area (which lies somewhat between Toronto and Buffalo, NY.   I've excerpted some of the 'engine related entries from that weblink above, as follows:

1952: The foundry was officially opened having the largest and most modern malleable and grey iron foundry in the British Commonwealth. [CLOSED END OF 1995]
1953: Contract to build an Engine Plant at this site was released on March 31st.
1954: V-8 engines for Chevrolet, Pontiac, and Oldsmobile Rocket engines were made and assembled in the newly completed Engine Plant.
1963: McKinnons acquired the Windsor Engine Plant. Inline 6 cylinder production was transferred to St. Catharine's with local transmission production transferred to Windsor.
1966: Engine Plant tooled for '327' CID VS Engines.
1967: Engine Plant tooled for '307' CID VS Engines (dropped 6 cylinder)
1968: V-8 capacity increased to 2,400 Engines/Day
1969: Engine Plant tooled for '350' CID VS 2/4 Barrel (dropped '283'). McKinnon Industries changed from subsidiary status to become General Motors of Canada Limited, St. Catharine's.
1970: Engine tooled for 100% '350' CID VS (dropped '307, 327')
1971: V-8 Engine capacity increased to 2,600 Engines/Day.
1975: Engine Plant began producing '350' and '305' CID VS production with full flexibility.
1978: Approved to manufacture '267' Cu. In. V-8 at 1,400/Day.
1979: Corporation approval to manufacture V6 60 2.8L Engines at 1,600/Day and V-8 4.4 & 5.0 Litre ('267' and '305' CID) Engines for 1982.
1980: Capacity increase on '267' CID Engines from 1,400 - 1,800/Day.
1981:  Corporate approval to provide R.W.D. V6 600 engine flexibility.
there was lots more in that article on this plant from the early 1920 thru the 1990's.. but I only excerpted the 'engine related' notes above.   They also made many other car parts in that facility over the years.

I never realized it was right beside Niagara Falls / Tonawanda.
Had to be for local content laws.

Thanks for sharing the info on  McKinnon.

Not sure if this question should be bled into a new thread but, here we go:  According to the CanadianPoncho McKinnon table
in 1954 were ALL V8 engines destined Chevrolet, Pontiac and Oldsmobile built and assembled at the McKinnon plant ?
Thanks!

NOT for cars to be build/sold in the US, and *perhaps* not even for all the cars to be sold in Canada..  This was seemingly in a period of Canada wanting their consumed items to be built 'at home'.. (so what's changed?? ) ..Smiley

An additional reference:  
http://www.camaros.org/forum/index.php?topic=1979.0

When I purchased my '69 RS in Nov 1991, although it had a 327 in it, it wasn't the correct '69 Camaro 327.  In April 1994 I was fortunate enough to pull a 327 from a '69 Camaro Coupe that was being parted out - complete engine, that is everything except for the heads - which I found a couple of years later in a '69 full size Chevy (Impala as I recall).  I later realized that although I had the correct heads with the correct markings, accessory mounting holes, casting number, etc. that they had actually been manufacdtured by McKinnon Industries and are clearly marked Canada - refer to the attached link and pictures below.

Not sure how those Canadian heads wound up in a full size '69 Chevy in a junkyard in south Louisiana - but they did.
