Sad to say that is a bogus document.

Any 67 Beaumont SD built after approx. Dec 1 66 would have a VIN starting with 738. Your's starts with 736 making it a small block car.

This is interesting, the switch over to 738 was in Dec 66, this is a 736 with A51 code ???

Yes, that would make it a bucket seat Custom.

I am pretty sure that is a 283 code but didn't want to say for certain without looking it up tonight.

Well its not a Big Block code that's for sure. 

Are you saying that is what came from GMVVS as the documentation for the car?

Code DE is for a 283 with powerglide trany.  I have to agree with Carl, that  one beautiful car.

not true 73SC My 67 SD was produced April 10th and its a 396 L34 with the "K" on the engine code and on the GM docs
some BB's did come out of McKinnon in St Catharines although very rare . An all Canadian car !
I questioned George Z and he confirmed after verification that it was correct .

 Mark - I'm going to PM you on this re: my documents on your car dated Oct 5, 1995 and our previous conversation about the McKinnon block

That car was built originally as a Beaumont Custom, plain and simple. It IS very nice and it has the SD louvers on the quarters. Great colour combo as well. 

The DE engine code is for a 283 Powerglide, 7.35 tires were not offered with a big block (they used 7.75-14 in 66, F70-14 in 67).

D55 is coded as an RPO on your documentation. When A51 stood for the Sports Option, the console was included and was not coded as it couldnt be added or taken away. After the Sports Option was cancelled, D55 became a new separate option that could be added or left off on a bucket seat car. 

You could get a Powerglide with the 396 through 1968.

 Only the big block cars used a bolt-on rag joint that year. In the U.S. where you could get a factory tilt wheel on a Chevelle that year, they also came with the bolt-on rag joint.

 

I am with Ray on this, I have never heard of a MacKinnon big block, only sixes & small blocks. Tonawanda was not a long train ride from the factory to the Canadian side; likely it rolled right past the St. Catherines plant on the ride around Lake Ontario to the Oshawa & St Therese assembly plants. 

Chevrolet did produce 454s at the Flint, Michigan plant by the late 1970s but other than that I am fairly certain that Tonawanda was the only plant producing big block engines in the 1960s & early 70s. Mark, if you have documentation to support your 396 as having been produced at the St. Catherines engine plant then that would be a first. Do tell!

...interesting thread here. By some chance did this year of car use a 5/16 fuel line from the tank for the 6's and small block 2bbl and a 3/8 line for the 4 bbl engines just like the older X frame cars ? if so would be worth just taking a look to maybe give another clue here.

Yes, that is correct Michael.

Also another clue on big block cars is the unique frame mounts for the engine. In this case, no need to look that far because we know it had a small block.

I just came back from an hour long highway drive and I was thinking about this while driving.

I am leaning towards a mistake in the document, simply because GM likely didn't even have it all sorted out when George documented this car. He may have the answer as to why it happened at any rate. I know from his past participation here on CP, he now has the whole 67 SD rats nest A51/738 thing sorted out correctly.
