Hi all, I have a pinto block engine number stamped CP4PXY... cast 70hm6015ba.. anyone know what it’s out of??? I know of CG and CK but can’t find CP anywhere

Can't solve the mystery I'm afraid, but it does make me wonder further what Ford were doing at times, as I have one with a common prefix but a weird month/year suffix that I can't decode.

Might be a bit difficult to take the decoding religiously.
These cars were manufactured with a high level of human labour.
Miss hits and errors in stamping were common place.
 
I own two RS2000's both assembled at Homebush in the last two weeks of December 1979. The vehicle serial codes show the cars were assembled 110 vehicles apart. This was confirmed by the manufacturing date stamps on many of the components of each of the Australian suppliers (eg wire loom, seat belts etc).
From what I understand the capacity of Homebush was approximately 100 vehicles per day. So the cars were only a day or two apart.
One of the RS2000's has an EB (German manufacture) block and head. Both matching casting dates of December 1978.
The second RS2000 block and head has no manufacturer markings (as usual). The block has casting code 5 K 5, which by the decoding principles shows is possibly 5th November 1975. There is no evidence of tampering or renumbering, or re-machining of the serial number landing area to re-stamp a new compliance code. Documented RTA searches show the engine block was never changed. Past owners (reliable) claim the car was in continual storage as a wreck from early 1992 when I purchased it 7 years ago. So I can't see any motivation for anyone to pull a swifty with the engine serial numbers.
 
Both serial numbers stamped on the blocks exactly match the chassis number. Fonts, sizes, alignments etc clearly are Ford.
 
I have a long history in engineering. One of the many things I have learned over the years is the Germans and the Eastern European countries in the old days simply chucked all of their freshly made castings (called green castings) out into the open paddock in open weather (continual hot/cold) in a huge pile to age and anneal (normalise and reduce internal stress) for several months prior machining. So even though the EB block and head decode to casting manufacture date of 1978 this would be correct for a 1979 manufactured vehicle because to the annealing period, the machining and engine assembly period, packing, shipping time to Australia (by ship), unloading, unpacking, and storing and then assembled into a vehicle, then the parked up in storage on "The Hill" at Homebush awaiting sale, and then more time doing the new car pre-delivery and shipping to the new owner. So 12 months could easily be realistic. Research shows both cars were registered in the first week of January 1980 so both were manufactured and quickly delivered to their doting first owners.
 
As Chuff commented on what he has seen: I have also seen several 2 litre engine blocks without the date of manufacture cast into the block as shown in the previous photo.
 
It is well known the EB castings were manufactured in Germany.
But which country were the non EB castings manufactured? There is no identifiable manufacturer or common code from what I can see.
 
:)

Thats an unusual one, haven't seen that style of alternator bracket, thermostat housing or rocker breather before.
Whats the part number on the exhaust manifold or engine mount? The prefix may give a clue what its come out of.

Typing 74HF into ebay brings up TC/D Cortina and Capri parts, also Ford Mercury in the US, where are you located?

I thought that looked like a US Pinto.

Hi, I am also querying some engine identification codes and would appreciate some clarification if possible.  We have 70HM6051BA Also BR64772.
We don't have a VIN number as we bought the engine which is to be the donor, no paperwork so no details, all we know is it is a 2ltr Pinto T6, so basically we are looking for any info on the year of manufacture.  These are the only numbers we can find on the engine.
Any help is very much appreciated.
Thanks

Perhaps try the Cortina or Escort forums, as the Capri never had Pinto motors fitted here in Australia, that might help!
