Any ideas on what this number means - stamped on engine block where you'd expect to see a plate - MS961 IE 0711
engine has many signs of a 1275 Cooper S - tappet covers, tall, headbolts etc.  Thanks

Looks like a modified engine that has it's maker's marking on it.

 

Afraid I don't know who, or any other details.

 

Would MS stand for Minispares?

well IF its an S then it would have no machined hole where the petrol pump would be but would have a rivited ally plate with either 970, 1071 or 1275 stamped on.......

Ask "[email protected]" (Screen name not email) he should be able to tell you if it's A motor they built

or MiniSport or MiniSpeed or MiniSomethingelse etc etc

 

But the as originally stated, it's a reconditioners mark so ideally to get the spec of the engine you will need to find out who built it.

 

Drop a picture up of the whole engine and will be able to tell you if it's a cooper S block or not.

I have an 1380 engine which is a metro turbo block with a similar code. Mine being MS585 DW 10/01. My understanding is that Mini Speed worked on the engine and the final figures are the date it was done. The middle letters I can't help you with.

The middle characters are the initials of who built it under the Mini Speed system I think. It does look like one of their numbers and they keep build records so give them a call.

Sounds like a nice build...

Interesting practice in the markings. Is this instead of the original stamping or as well as . ?  It is great that a record has been kept of the build?  not sure if info should be made available to anyone who asks? - did we get the owners permission?  and if it instead of the original (9 FSaY as example ) i would want that preserved,, but i know sometimes the machinists don't do this ..

For the simple fact that the engine number describes the specification of the engine... if you change the engine's specification then you should also change the engine number or provide documentation which then supersedes the previous specification...

 

Most of the time engine builders will renumber an engine, and have documentation to support that engine number. This is now required by the DVLA when changing details on the car.

 

You may keep the original engine number, but then the publicly available information on engine specifications no longer apply which could be considered a reason for deception, misrepresentation or even fraud, especially when considering insurance.

[Scott@minispeed]

Hi it is normal practice for us to use one of our engine numbers on a custom engine build as it makes it easy to identify the specification for future support etc and as part of the branding, and the engine tag is removed when the block is surfaced, but if the number was important to a client then we would replace it as was if required.

thanks for the replies guys, i was not familiar with the DVLA requirements, (whatever that stands for) , it is a very good way of checking what is inside, something that is always a bit of a worry. Guess works , i hadn't thought of the insurance angle - in regard to mods. Thanks to Scott for clearing that up.- thorough system - just want you would want in a engine build -   Cheers  and back to the original post - sorry for the hijack - it does indeed sound like a good build
