Re: weird engine manufacture code
 

I don´t know if this is off subject but in the early sixties the Canadian-built engines didn´t even have an ordinary suffix-code, just a number. I believe the pic I have attached is of the enginenumber, not the partial VIN. The partial VIN was not stamped on the pad on the engines I have seen.

Casting date. The casting # is 3849852.

I checked my stamping last night and it is "3S" on the block, so I guess I have the rarest 427 in existence at 1 of none. https://www.yenko.net/ubbthreads/imag...mlins/wink.gif

These odd codes are very common on the canadian cars especially the full size for some reason.I have never been able to find a list to cross reference them like a IE or IH code but can assure you they were correct for some canadian cars.
Brothers 68 ss427 which has been documented by George has it's original born with engine which is stamped T01113T and it was a l-36 4spd. We also have in the pile somewhere a T01113S which we took out of a 68 pontiac 4spd.
Many of the canadian cars had these number /one letter codes but I don't know why.

Re: weird engine manufacture code
 

I have seen some American built fullsize chevrolets with engine codes for 68 D2 and H3 and for 69, F2 and F3 and these were V8 engines. All were flint built engines with a V as the plant designation. I haven't been able to find anything on these codes in any of my books.

Re: weird engine manufacture code
 

Very unusual. Interesting that the codes are different, I just can't help wondering why the factory would use a different code than regularly used....I wonder if the "3T" code was for close ratio trans, because we have two wide ratios known with "3S" designation?.

I thought it may have something to do with one came out of a impala and one out of a pontiac but I don't know. For what it is worth the 3T was a close ratio 4 speed.

Re: weird engine manufacture code
 

The car I mentioned is not mine,but is still with the original owner.Hey 3macs,tell me more about that '68 Pontiac.

Re: weird engine manufacture code
 

I have a 427 that has an odd stamp as well. I could never really find any information on it. The general consensus seemed to be that it was a marine application or something like that. The engine is a low mileage 512 block, std everything, that has all the guts of an L-88. 7115 crank, 7/16 dimples, etc. I'm not trying to hijack the thread, but thought I would post a pic of it.

Another interesting one for sure and not included in the regular 'known' Marine or Canadian suffix listings?.
Take note the Tonawanda build is 0325 so the suffix should be the '7BL' not the BL alone?.

On the other unknown suffixes, TAR6569 are you saying these Flint plant engines were Mk1V's or Small-Blocks as I always understood Tonawanda was the only source for MK1V's?.

As a side note on small blocks, don't forget Canadian-Hamilton built 65/66 Studebakers had McKinnon sourced SB Chevy engines after South Bend closed.. I forget if they're numerical or not but they occasionaly pop up as a loose SB..

In most Canadian numerical suffixes I recall seeing, the rest of the plant and build number is 'normal' and unlike Ander's example?.

As mentioned previously I have an old Canadian book (not a GM publication) that lists lots of the numerical suffixes but not the previous examples...have to look again for the recent additions?.

Nothing to do with it but interesting to note how Canadian assembly plants have a numerical designation too, unlike US plants which have a letter...Oshawa vehicles always had a number 1 in the Vin..

Again, anyone have recent contact info for ex Tonawanda plant Chevy guy Fran Preve?. I haven't spoken w/ him in a few years but he once told me he had saved what was left of internal documents when they were being tossed and may have some more info on these unknown suffixes?.
