It is possible that the block is a replacement for a damaged original. I personally know of one in particular where the original block had both sides punched out by #3 conrod back in the day. The owner/dealer simply got in a new un-numbered block and factory tool re-stamped the correct number for the car chassis number/license records. All this was done within the dealership and was considered to be normal course of events to keep everything legally correct. Given that the blocks were all the same from that period on, there was nothing special about a GTA block other than the number when it was allocated to that model.
I have the original holed block as wall art. (well, under bench anyway)

The seller has responded to my question that the cylinder head is a correct 1600 GTA.

Yet It does not look sand cast, there is no part number cast across the front and there is no serial number cast on the exhaust side, all that I am accustomed to see on GTA 1600 heads.

Can someone familiar with the 1300 GTAj head please have a look and comment, here.

Thx

Ken

Ken,
The head looks about right for the later die cast 1300 and 1600 version, including markings on the front.
I suspect the engine is actually made up of separate item parts and built up into a complete engine.
Still a worthy assembly of some hard to get parts.
I'm building up a 1900cc monosleeve GTA engine from parts that have certainly never been together before. I have them as loose items collected over years with no real purpose, so restoring GTA 752556 with a big bore period GTA engine for road use seems like a fun thing to me! Original engine safely aside, refreshed and in the corner to remain with the car.

Hi Matteo,
We must have been typing a response at the same time. Funny, we almost tell the same story! And both RHD GTAs, what a coincidence!
Regards, Vince.

There are basically 3 series of early 105 1600 (cartridge oil filter) engine block.
The first: With unreinforced mains below bores, scalloped bore holes and flat #5 rear cap. 18.4kg.
First sedans and GTs.

Second type: reinforced webs main area in block at #2 & #4, thicker in #3. Scalloped bores holes and flat rear #5 cap. 19kg

Third type: reinforced web mains #2 & #4 and thick #3, No scalloped bore holes and new arched #5 rear cap. 19.5kg.

GTA blocks are typically the third type which became the standard production block across all models by about '66 maybe.
