Hi all this my fist New Post on Fastlane, I have the above for sale but I was not sure if it's out of a HT or HG Monaro. I bought it 33 years ago from Eagle Spares. I was thinking of building it to put in my original 307 powered HT GTS Monaro as a 350A Tribute car. But now i'm not going to do anything silly like that. My car is already as rare as it is. The engine number is 350A4XXXXX0612 and the block casting date is 13-F-9.
If anybody can help me, thanks.

If it is a 4 bolt and has its original number on it someone stuffed up at the Dandenong assembly plant and stamped A instead of M.

Although having said that it could simply be an error at the Tonawanda assembly plant where they used a 4 bolt block by accident for a 2 bolt application.

I wouldn't be too concerned putting a 350 in your HT. I have a HK GTS V8 auto, it is currently the oldest known V8 HK GTS recorded. I'm putting a 350 or a 427 in it, pulling the 307 Powerglide and banjo out over Xmas and storing it.

Thanks HK, ive' put the add on Gumtree, so pictures of the block are there. When I bought my car in 1984, the original engine was not in it, it had an American 350 T400 in it. But it's an 808 ID Tag. It also had 5 litre badges and the 307 pulley system on it. But its still a good car because it is one of the first HT's from Dandy. ie: body no.0000001XX. It is Spanish Red with factory power & Air.
Do you think it is safe to put it on the Monaro register & who do I contact. Thanks.

Ben at HHS for the contact about the car. It is a car that will interest Ben as he is a HT fan, he has one of the rarest of all Monaros, an early HT 5litre manual which also has air and steer. Agree it is a good car to have, but I'd save your $ on restoring a 307 driveline, and use any SBC in it. But that is just me, once the original engine is gone can't see the point in fitting the wrong 307 back in. I would have had a perfect 307 for it too if it was a Pagewood car, and all my 307's bar one are from Pagewood vehicles so no good for you anyway.

Just looked at your block on Gumtree. It has been restamped, and that number is not original to that block. It is not from a GTS350 as it is a McKinnon cast block. Scratch at the cast number too to make sure it is original, reason I say that is I have NEVER come across a Canadian cast 618 block! Or for that matter a 4-bolt Canadian block from 1969! As far as I was aware McKinnon only made 2 bolt engines at this time, but there is still stuff to learn on these. Does it have 618 under the timing case cover too? You can see the McKinnon mark in the 4th picture between the cast number and the 3, plus the date code is on the side of the block and in the Canadian format.

A wave of an oxy flame across the engine number pad should reveal the original engine number too.

HK1937, what led you to think it has been restamped?

Because it is a Canadian block, but other stuff also like the font and the fact it is 350A on a 4 bolt block.

Plus the elephant in the room is the cast date is later than the completion date.

Hi Guys, yes I will investigate the block further & get back to you. Us old Victorian guys know that Eagle Spares, at that time used to bring all kinds of second hand stuff over from the states in containers. So it wouldn't surprise me if it wasn't imported for Monaro buyers or Drag Racers. They used to support Peter Ridgeway and his team drag racing at Calder etc. (back in 1984).

I suspect your engine number is real, but someone has stamped it into an imported block, probably after a failure. If you chase AOMC up and do a search on the engine number you will probably get back the chassis number of the car it was first registered in. So chase them up with both 350A47xxx and 350A47xxxT0612 and see what you get.

OK thanks HK I will look into it when I get time. Anyway looking further at it, it has a Fuilie symbol cast on the back of the block. On the Top drivers side and is Drilled & tapped for Clutch linkages. Apparently some blocks were not drilled at this location according to an old magazine I have. Do the aussie blocks have these? Thanks.

Not sure what you mean by Fuelie humps on the block? That is a head thing. In a passenger car this block would have had Fuelies on it, either 186 or 041 depending on which assembly plant assembled the engine. In passenger cars 4 bolts were only used on 290hp upwards for 1969 model engines, which means only L48, Z28 or L46. My guess is it was cast for the Flint V8 plant to assemble, as I have seen 186 cast heads cast at Tonawanda but machined and assembled at Flint V8 too. Flint V8 never cast its own stuff, it mostly came from the Saginaw casting plant, but this time in 1969 was a turbulent period with strikes across various GM plants which caused GM to cancel 1970 models which would normally see start of manufacture in August 1969, and delay 1970 model introduction until January 1970. This is why 1970 Camaros are called 70 1/2 models. So it is possible that Tonawanda and McKinnon were asked to cast stuff for Flint.

But as it has the clutch Z-bar setup on it, it probably was a truck block, these are 4 bolt but can be 2BBL. So in that case it may well have been McKinnon assembly too. But I'd put money on it being either Flint or Tonawanda assembly. We regularly see Tonawanda assembled L48 engines that use Saginaw blocks, so this could be another source for the 618 blocks not yet seen, or it only happened for a short while due to strikes etc as already mentioned.

Thanks for the interesting insight, you're right who knows. Anyway I put some extra photos on the Gumtree add, including the double hump symbol I was talking about. Also as shown there doesn't seem to be any stamping under the timing cover to indicate a plant. Also I applied the oxy torch to the engine number pad but nothing showed up.

Hi all, an extra 2 photos have been added to my Gumtree Add. I got caught out by the 4Gb. limit for photos, so they did not go on. Thanks.Think
