ok heres the numbers ,one of the numbers was wrong,thought the 5 was a 6..skinny tag reads 81837H 519141 says above number general motors holdens pty ltd .. large tag reads HK81837KR-00105-H5 trim 1173-12X paint 568-10846 ..says on top of plate general motors-holdens pty ltd then under that in letters a bit bigger body identification, then in smaller letters under that correspondence must bear these numbers.. down the bottom of large plate has made in Australia and in bottom right corner lion holden emblem with holden written in tiny plaque under it. all the numbers are nice and crisp and are all perfectly stamped at exactly the same depth,looking from the back of the plates..the numbers on the skinny plate are set at a very slight height difference after the H and starting with the 5 being a little bit higher..thankyou for your time.

did they ever make mistakes when stamping these plates, maybe the 1 is supposed to be a 4 or a 7,??? it would be good if I could find a Sydney car close to the 105 build to compare plates with..thankyou .

what can I say, I am shattered by this news,have been chasing up parts for this car for years,thanks for your help in clearing it up..i will concentrate on the other car now which is an Adelaide build.thanks again .

Both, except LTD is LIMITED on the first one mentioned. It changes during the 70's.

I asked Ben about the Mosman Park and V8 HK thing. He reckons there are a few hundred of them, he has engine numbers up into the 30790200's. Mosman Park did assemble some Monaros too apparently too - I was with you Warren, first I've heard of this. Some have come up though, Elizabeth built, Mosman Park assembled like the HK ute described in previous posts. Ben's take on 307P2951 is that if this is a mis-representation of the original engine number for a Mosman Park HK ute chassis number HK43924AP optioned with a 5litre engine, it has to be 30790295 or something like that. It is also possibly a jumbled mess of the GMH stamping and the McKinnon Industries stamping after an engine decking, the original number would have been something like 30790295K0713 given the timing of the Elizabeth body.

It isn't a McKinnon casting with the date code there, my guess is almost certainly Tonawanda. Very odd that you have a Tonawanda cast 327 with a McKinnon engine number.

Looks like it may actually be a Flint block, appears to have a little tapped plug in the front of the block just to the right of the engine number.

...Jeeez mate .. after about three pages....I think we all might've forgot the question !! LOL

It may be Tonawanda, just the little oil gallery plug at the front just below the filler tube made me think it was possibly a Flint block, but it may also be a truck thing.

In 1967-1968 there does seem to be specific castings at Saginaw, Tonawanda and McKinnon and in the 1969 rationalization they all seem to become common.

This one is essentially identical to the earlier one from the thread of FE327CHEVY's:

Tonawanda 352 block assembled by McKinnon Industries.
Canadian 482 heads.
A 5 digit number in the same font preceding the engine assembly code.

Any photos of the intake manifold?
This definitely came from a GMH assembled 1967 Impala? If so I reckon FE327CHEVY's also came from a 1967 Impala or Parisienne.
Do you know which GMH assembly plant assembled the car?

According to the info I have McKinnon didn't tool for 327 until 1966 and 307 in 1967. It doesn't say when in these years they started casting and machining either though, but I know the 307's were being cast and machined at McKinnon by 9/67 as I have plenty of early HK 307's cast and machined in September 1967. It is possible these are close to the last of their kind.

Those 3814482 heads are 75cc heads, which means the 1967 engines were about 8.55:1. So now we have plausible explanations for the 4BL low comp 327's power increases:

1966 was 230hp.
1967 was 240hp, increase due to the new Quadrajet.
1968 was 250hp, increase due to the compression ratio hike from just over 8.5:1 to just over 9:1.

It does appear that there were different casting numbers used between the US casting plants (Saginaw and Tonawanda) and the Canadian McKinnon plant up until 1969 when manufacturing was restructured. This is probably why the 3917290 head of the Tonawanda 1968 HK 327 head is a different casting number to the McKinnon HK 307's 3911032 although the heads are identical. Same for the HT manual 350 engines, they got 3947041 heads which look to be the exact equivalent of 3927186 heads, and Tonawanda 3947040 heads are the direct equivalent of Saginaw 3917291.
