If it's anything I could help with, I'd be happy to assist, :) though as I don't have the basic info (hence the question! :wink: ) and I'm not one of the wiki-people, I may be a bit limited?

As former Reg', I do know that we used to collect engine numbers from the owners and place that on a spreadsheet in production number order. Once you have that, you can more or less fill in the blanks for the missing cars. Though with GTC/6B production there are a few anomilies with chassis number versus expected engine number. This is at the time when the factory were concentrating on either GTE or GTC production.

I don't think the DVLA worry too much. I replaced the engine in my Citroen AX some years ago with a Peugeot one and just notified them of the change of engine number. There was no problem, I was just issued with a replacement V5C with the 'new' engine number.

I'd heard similar about DVLA not being too bothered about a classic cars engine change, however I can't find anything on their website about it though it has been discussed at length in the classic press

As Phil said, I added the engine column to the GTE database (SE5 - Middlebridge) when I was first registrar and later all registrars used the same column format. It's not quite one for one - as you would expect (with cars and/or engines being pulled from the line for testing or fault rectification) but many blocks of engine numbers are 99% linear. I also did a 6b & GTC spreadsheet which gave us the order of production (assuming engines were numbered sequentially - which was a fairly safe assumption from extrapolation). This engine numbering later gave us a more accurate guesstimate of Ti engines in small sports (which Reliant didn't stamp) - by assuming the gaps in the (linear) CVH numbering system were Ti.

It wouldn't be difficult to populate a rough spreadsheet of chassis/VIN to engine numbers (in rough blocks) - if the registrars have no complaints it'll take me about an hour? (The hardest part is coupe/SE5 which have a large overlap)

many thanks jim, that answers a few questions !! have managed to scrape off the additional paint and found the whole number to be sc4856, looks like a previous owner has swapped the original carb etc over, as i have the DFAV weber not the DGAS, any idea if better or worse for it ?
cheers

Worse fuel consumption, better max power (in general terms)

When I swapped the engine in one of my GTCs (HOM 450W) from a Cologne to 2.8 to an externally identical stroker Cologne 3.5, the DVLA couldn't be any more awkward. They requested a letter from a garage to prove that the engine number "I" said was now in it was correct. They also wanted measurements to prove the new displacement figure, and have a letter from the engine builder to back that up.

It go so wrapped up in awkwardness, I just left the paperwork as it was. :roll:

Maybe the DVLA have now had a policy change, or whoever dealt with my enquiry has left the department :lol:

I'm hoping the fact I've fitted a different 3 litre engine (although the cc is slightly different) it won't be much of an issue with mine.. :w Insurance company were happier that it was another 3 litre engine - even though from a different manufacturer and (over) 50% more power.

Hi all
I knew I had a later engine in my 67 Coupe as it had the side dipstick like my 1972 Gilbern Invader. I had a look for the engine numbers -SC4404 30U and 2F 14. Good news- your discussion indicates it is from a Scimitar, Burton show May 76 or Jan 95? So what do the other bits mean?
Cheers
Nige

Burton Power is wrong - the engine is originally from a 1972 GTE but is a D Port engine.

It's not really that Burton Power are wrong, that's misinterpreting the codes. The Burton Power listings are for Ford engines *in Ford applications*, (where the engine number is derived from the accompanying Ford car chassis number), and where the "SC" code has the relevance in the table. For a Ford engine supplied to Reliant for use in a Scimitar, the "SC" = "Scimitar" and doesn't have any relationship to the Ford dates table.
