Where did this 327 originate


I have tried to look it up but found too many conflicting answers, so I am going to ask the more knowledgeable for there answers. I know what the previous owner said it was from but I have my doubts. It is a 39146789 327 block cast 4/68 suffix code I believe is VO410HHIMG_4233.JPG

The casting has to be  3914678  not 39146789. The engine is from Flint and it was installed in a 1968 vehicle built in Oshawa. Its a 2 bolt main bearing engine. What did Oshawa build in 1968, I'd say B body and A body cars. I do find it interesting that an an Oshawa car has a Flint engine so it could be from a higher horsepower application. 

What did previous owner say?

Thanks
Sorry about the extra nine typo. The elderly fellow I picked it up from told me a story of his neighbor who wrote off his corvette and he acquired the engine and then it sat in his garage for many years. But I could not find any site that backed his claim. I did find some info that it could have been an impala engine, and while back a fellow was selling the same 327 with the same code and numbers out of a Parisienne. I am leaning towards the latter beginning.

It did have a forged large journal #4672 crank in it. Runs great in my car right now.

The 181144526 tells the story really. 181 means Chevrolet, 1968, Oshawa, the remaining numbers are from the Vehicle Identification Number of the vehicle installed in. 

IN 1967 and onward all Corvette small blocks would have that V code for Flint and the casting was also used for 300 hp and 375 HP Corvettes in 1968 so that's where the yarn is coming from. Add in that HH code was a 1965 Corvette code. Corvettes were not built in Oshawa...obviously eh!

So unraveling the codes is not straight forward with Canadian cars and engines because all the information available is US dominated.

The V Flint code is telling me the engine is a higher horsepower engine because McKinnon in St. Catharines didn't make those applications for Oshawa builds normally a Canadian car is coded with a K for McKinnon. 

The HH code does not show up on any US decode sites so I'm going to deduce it is a Canadian code for B body Pontiac, aka, a Parisienne.

So in the end I'd say the engine came from a 1968 Parisienne (or other B Body Pontiac) 275 HP 4bbl 327.

One of the things I love about this site is how much knowledge there is here and how willing everybody is to share that knowledge to help somebody out!

It amazes me how many people who say their car has a Corvette engine when they are selling it or talking about it.  It happens so much that I never believe anybody when they tell me that.  All the time I'm wondering where all the poor Corvettes are sitting around without engines... wink

Interesting info on trying to decipher the origin of this engine. Although not quite related to this thread, there was an indisutrial 327 that showed up in Ontario built Massey Ferguson 510 combines. We had one in our farm and from what my father told me, they were 4 bolt mains. (however this might not be the case in terms of 4 bolt mains, they could have had just larger bearings? I am not entirely sure as I have heard GM did not make a 327 4 bolt)

Anyways, I have never seen one apart so I cant verify that but that 327 was a powerful little engine. I was a small kid back then and I can still remember the two straight exhaust pipes glowing bright red at night when the engine was working. You had to be careful thrashing because if the feeder house took too much material in and plug, the engine would not stall and could end up burning the drive belts right off if you didnt disengage the drive. Anyone ever ran across one of these 327s? Not many are in the combine junkyard apparently as they were removed and found new homes after the life of the combine was exhausted. Sorry for sidetracking the thread!

Love hearing this kind of information 68 Grande, I guess its in my nature to do research and come up with logical explanations on these details. 

The 327 was also used in marine applications so being used in farm equipment isn't really a surprise , afterall it was and still is one of the most favourite and pound for pound powerful small blocks ever made. 

McKinnon held the initial license to build these engines in Canada and in fact became a subsiduray of GM then today it is actually GM Powertrain.

I have never seen any information to suggest that a 327 was produced either in Canada or USA with 4 bolt main bearing caps for automotive or truck applications. That's not to say that GM Canada didn't spec a casting with enough metal to install the 4 bolts for heavy duty farm equipment and afterall Masey Ferguson was a huge Canadian manufacturer and in those days could likely work with GM on getting the engine design they specified.

I have been fortunate enough to take a trip on Lady Eaton's 1922 Motor Launch in Gloucester Pool and up the Severn River in Ontario and it was re powered with a Marine 327 in the mid sixties. I understand that the marine application intake manifold is as good as it gets for power and flow and is easily transferred to a hot rodded 327 for road use.

So now we are really off topic smile
