I read an interesting article last night that said the 6cyl Biscayne was dropped for 1967, leaving a 250 and v8 as options. The Biscayne four door code is 1539 like mine. Now my engine was made early Feb. This I'm not sure but I have read somewhere before that stolen cars or ones that had a new engine put in as replacement needed to be inspected and the local copper or rta would stamp one number on them. I'm thinking that usually the prefix ce for truck or impala codes would be done in Canada as an assigned engine in the kit. Well what if a bloke ordered a Biscayne early in the year and the dealer didn't realise the car had been dropped. Not sure if orders were hard copy but I'd think so. Then perhaps cos there were replacement engines, this one being a truck one, was there maybe the order was changed cos of this so it got the 1539 number and the big 3 number was done by the rta because the code on the vin would have then been different to the car and not matched. Either its a truck motor or Biscayne replacement in my opinion. Our impalas had the lower spec engine, rather than the 275hp and id suggest a Biscayne would have had the lowest spec.

Another thing for general discussion is that the heads on mine were also offered on 350 motors in Canada. I'm assuming that the Canadian truck plant used them for 350 trucks. Truck plant was in Flint in 1967 and further parts of mine have "F" stamps. So do you know if truck blocks were made at Saginaw then sent to Canada? It makes sense that they had tooling in Canada for my heads cos the truck plant used these heads for 283's. So I think car heads on later hk were different because of my truck heads or police or whatever, were given hardened valve seats, 3/8 guides, rotators and double valve springs and timing chains.

Did hk have double row timing chain?

So, mine also could have been a copy police car hence the number 3. Could be same scenario as I described earlier for police cars cos I read that they had to be copo optioned cos they used drum brakes to use steel wheels in your city cars. Or could have been a copo taxi.

We're the hk heads used exclusive for those years? I still think it's more likely that mine is from a low volume truck given it was a country motor. The fact that the block is Flint and that's where a major truck line was makes it even more plausible because why would they change systems for supply of blocks to Australia just for hk etc. The block I have was used in a heap of cars, all major high hp types, which makes sense too.

I'm just unsure if they had engines here for special occasions etc. Would take too long to get them made over in Canada.

Now I wanna know the specs for a police car motor lol and cabs. I think I'll ask a club if any members have any. It's cool I think how mine doesn't have any body or markings of a body or model cos its going into a custom Holden, dressed as a 50's 265. So the simpler the better.

So the 390 cast was used and cast in Canada? I didn't think the same cast number could be made at 2 locations? I assumed the range of cars was too many to be cast outside of Saginaw. Not sure but do the hk blocks have a "t" before the date? I think they do. I would have thought cos trucks had their own line that blocks were shipped there but engines were assembled in Canada. Otherwise, why wouldn't the export cars have Canada cast blocks? I could be totally off track or confuded here. So why did tonawanda build Holden motors anyway? I know the factory did lower numbers than flint. The block I have was used in more models than available in Canada I thought. So I am wondering if Saginaw didn't mark their intakes cos they were the main foundry? Do you get me? Also, were some engines stamped here or were they all stamped with K in Canada. I didn't know if it was possible that the numbers were written down and not all stamped in Canada. We're engines all assembled over there or here. Sorry for all the questions, I'm just interested in the history. Depending on this process, my theory of blank engines kept here for special reasons could be quashed lol.

this is a 327 I have I think it might be out of chevy car 32712118 date is t12073q has same casting number as aussie 327 hk motor and same head casting as hk 327 series one..i bought it thinking it was the right engine for my hk Monaro,only came from sump to heads no intake block is 3914660 heads are3917290

no intake or carby unfortunately, I have a couple of intakes here, some have r cast on them and some have t, which would be correct for a 327 hk ser one please..it does have a hk sump on it,which is why I thought it was correct for my hk, but have been told now by a couple of people probably Pontiac, thanks for your help I,ll keep searching..

ok thanks have a few of these 3919803 inlets and just noticed that some had r and some t must not have looked properly..trying to collect bits for my warwick 81837 its a Sydney build, thought I was onto a real winner with that engine being a Sydney build,oh well only paid 300 for the engine,so not to much of a disappointment..slowly finding the bits I am missing.is there anyway I could find out when my car was built from the id numbers its h5 so I am pretty sure that's Sydney, yellow with Goya red 12x

Pretty close to right. The C168 could easily have been off one of the first batch of Tonawanda GTS327 engines, more than likely off a T0319 or T0320 engine. The E248 is possibly off the last batch Tonawanda GTS327 engine but these were July so unlikely. This one is more than likely an imported one or off an Impala/Parisienne.

sorry to hijack your post with all these questions, skinny tag reads 81837h519141..large tag 81837kr00106-h5 trim 12x paint 56810846,

A year or 2 back I had the original 327 from my RHD Impala rebuilt. Once it was cleaned and stripped, I took photo's of every number, marking, etc that I could find.

I know the carby wasn't original. I checked the numbers from that, and it was from a mid-70's Californian (smog regulations) built Big Block.

Any interest in me posting the images?

just spoken to a bloke with a factory 307 ute hk, have you ever heard of a 307 engine number with a p in it , he is the second owner of the car and bought it of his uncle and swears the engine has never been replaced it is 307P2951, also the firewall number has a p in it under the a for Adelaide build,firewall is 43924A with the P under it.. thanks..

Before you go spending $ restoring this car i'd go and get it checked out, especially the tags. Neither the VIN plate or the BODY plate appear to be original GMH stamped plates. If you got the car with that Impala/Parisienne engine my guess is someone got a VIN plate made up for a GTS327 using the VIN plate off the Chev/Pontiac. The PSN dates this VIN plate around late 4/68 - way before Pagewood assembled a Monaro let alone a GTS327. The BODY plate has issues too that indicate it is non-original. If who you got it from is still around i'd be chasing them up, if they wont come to the party seek the Police.
