Are there any other casting or stamping codes on the 327 engine that indicate "Canadian Built"? I bought this engine a long long time ago in Hamilton, Ontario and it has the ZI suffix code on the front passenger side block pad, which I was told originated from a 1966 4 speed car.

That is a interesting question... The fellow in Seaforth Ont. who has the 327 for sale, also said, he had a 396 that was "coded" as a Canadian Beaumont engine Is that possible? and another question, Did Pontiacs have Chevy engines with specific "Pontiac codes"... Which would lead me to ask, if Acadians and Beaumonts had Chevy motors with specific non Pontiac codes.... no really

Carl-I have the codes here somewhere for Leo's 396 I believe it turned out to be a full size car 396 engine not beaumont-any word on the SD rag in Montreal ? or did it go out west ?
My 66 Grande Parisienne 4 speed was originally a 396 4 speed, transisitor ignition. It had a the block code specific to those 3 things and that code was the same as a 66 Impala if that helps.

Hmm, then it may well be different. I have never seen or heard of an L79 that is not a 362 block. Then maybe the Canadian ones are different. It is the style with the recessed oil filter pad?

carl, don't forget the chevelle L79s, they would be a different casting than the recessed oil filter nova blocks.
True, but the ZI stamping should be unique to Nova. That is the part that intrigues me about this one. However, I have never heard of anything but a 362 block for an L79 Nova. If it wasn't stamped ZI, it would make sense for Chevelle or Vette. There is rumours of the 721 block for L79 Novas too, but I am not sure that is proven.

Have you checked if it's the Nova specific block? The rest sure looks fine, but it will certainly be unique if it's the Nova style block with that casting number.

My '66 Acadian Canso has an engine code that has a 77-*****. There is only one line on the engine boss, from what I have seen the USA vehicles have 2 lines. My shop manual shows the 77 code is for Acadian 283 with powerglide. Dan

Dan, is one of those numbers the last part of your VIN? Seems to me someone said pre- 68 the Canadian cars didn't have the partial VIN on the block. Or is it the date of the machining on your's?

My vin# isn't in my engine #. I have heard that the Acadian engines were randomly pulled as needed. There were only 3 engine options for the Acadian in '66, the 194-6, the 283 V8 (2 barrel carb only even on the SD model), and of course the L79 Acadian 327-350hp V8.
I have the early GM information sheet with 55 cars listed. It's hard to figure out what was the engine codes but it looks like if it started with a 61, it appears to be a 6 cyl with powerglide, 01 looks to be a 6cyl manual (3 spd), and 17 a V8 3spd manual. This is just my observation of the models and if they have a M35 or M20, or not.
Back to the L79 info. I found a copy of a GM Canada documentation of my buddies '66 Canso SD with L79. His engine code is FO222ZI (222 not his #). I don't know about the ChevyII's though, they may have 2 rows of numbers... Dan

Well I haven't looked at this engine for many years I just had some numbers scratched on paper regarding casting dates, engine block and suffix code numbers on the engine pad. Yesterday I went to the "barn" where I have it stored and re-investigated. I also took some pictures. The numbers on my scratch notes were ZI and then a series of numbers. Upon closer inspection now it may read 21 and then a series of numbers. Only one line of numbers that does not appear to END in any "Letters" which is where the ZI letter code should be. The last two numbers on the single line of numbers read 26 or could this be ZG? I think they are all just numbers though.
21 66XXX26
I apologize for my misguided "take" on this. I'm just learning as I go.
The engine has the double-hump heads, which I always thought were the 2.02 heads...but next time I'll take off the valve covers and get those casting numbers to make sure of what they really are. I received this engine in 1978 minus intake, carb, distributor and exhaust manifolds and cam. I can't recall if the former owner mentioned that he pulled this engine from a Nova or an Acadian...which he raced in the early 1970's. I can't recall if the pistons were domed or not. When I had it rebuilt in the late 1970's it was installed in a full size GM car and was surprizingly, very quick. I intend to have this engine rebuilt and use in my next project.
I'm still curious as to the origin of this engine...U.S.? or Canadian? Thanks for all your help on this. Very much appreciated.
I see it has a spin on filter. It's tough to see but it looks like there is an aluminum spin on adapter between the filter and the block. If so then it is not the Nova style block. Can you confirm, is there an adapter, filter to block?
If you like, I can post a pic of a Nova style block to compare.
