Hi, this has been mentioned in the introduction section of the forum, but I thought I'd put it in here which seems more appropriate. I'm trying to find out when exactly my Australian Austin 1800 was built and was hoping that someone else might have a chassis or engine number close to mine which might help to pinpoint it. It was previously licensed in another state as a 1969 but that doesn't really mean much as I have other cars (different makes) that have been licensed as "x" year when they were in fact "y" if you know what I mean.  The VIN on my 1800 is YH956471 & the engine number is 18YDTAH7707. It's a Mk 11 manual finished in Sugar Cane. Any info gratefully received! Thanks. Dave. |

'69 would indicate a Mk. II, but it's not an 18H engine?
13" or 14" wheels? should be 14" if she's a Mk. II

The wheels are 14 inch. It's a Mk 11 but just not sure of the year. '68, '69 or '70? What's an 18H engine? (excuse my ignorance :  Dave |

Your engine number indicates it is an Australian engine for transverse installation with high compression. I am unclear how this relates to the 18H Ul engine spec, see below. see landcrabs.proboards.com/index.cgi?board=talk&action=modifypost&thread=256&post=178918H refers to the engines fitted to UK models from the start of the Mk11 model in 1968. These have 9.0:1 compression engines with larger inlet valves than the Mk1 and 14" wheels. Previous numbers for the MK1 cars started with 18AMW (Austin/Morris/Wolseley) and I have seen reference to 18C as well. 18H was used for horizontal - ie fwd units and 18V for MGBs from circa 1970 and also for Marinas, the V meant vertical or in line. In England you can tell the approximate year of a car by the code on the side windows, not sure if that system was used in Australia too? Regards David The wheels are 14 inch. It's a Mk 11 but just not sure of the year. '68, '69 or '70? What's an 18H engine? (excuse my ignorance : Dave |

I've never heard of a code on the side windows so I'm presuming it doesn't happen here.
Thanks for the info you provided though.
I might end up having to take the previous licence year in another state as fact. I own Jaguars too and with them there are registers floating around that provide the build dates etc from the chassis numbers, but not to worry, I'll keep looking.

Whilst trolling the 'net I came across this piece which is about the Australian engines which might throw a bit of light on it:
"Just to go a little further with Gary's post, from some (knowledgable) responses I've obtained, it appears that 18Y/TA/H..... refers to an Australian built (completely cast and assembled in Australia) 1800 B series engine, fitted to the Australian assembled Austin 1800. We think that 18Y/DTA/H..... refers to an Australian Austin 1800 Mk2 destined engine, with the modified head of the same period MGB, viz larger inlet valve and the peak of the combustion chamber "heart" ground back a little. (Not sure about the MGB camshaft Gary, though you may be right.)
Apparently to fit these engines to an MGA requires quite a bit of work, including smaller bolts for the sump (threaded inserts to screw into the base of the block are available) and the oil pump mounting dowels need modification.
Overseas folk are often unaware of how extensive BMC (Aus) facilities were. They cast and built their own engines, gearboxes and rear axles, amongst other things over here. Some products were unique to Australia too, such as a 6 cylinder version of the 1622cc B series engine,(2430 cc), introduced here to help compete against the 6 cylinder Fords and Holdens of the time. It was incidentally this 6 cylinder engine that was used in the first prototype MGC, and from what I've read, probably suited the car a damn site more than the ultimately fitted C series Morris derived engine the MGC was burdened with.
Despite the extensive local facilities however, Australian assembled MGAs and MGBs were always fitted with engines and gearboxes assembled in the UK and shipped here from the Cowley plant."
