Hi all,
I hope you can help me, I have three engine/gearboxes I will need to overhaul one for my Ute so I am looking to try and understand the engine number sequence and what it means, of course your advice as to which engine would be the better doner.
Engine #1 18YE/RC/H1820 has a map of Australia at the end of the number, also has a mechanical fuel pump.
Engine #2 18AMW/U/H60317 no mechanical fuel pump (I think this was the original ute engine)
Engine #3 18Y/TA/H4574 has no mechanical fuel pump
If there is a sourse of information that explains the numbers that would be great, thanks in advance for any assistance.
Aussie Tony

Tony The only number I recognise is the 18AMW/U/H60317. 18 = 1800 cc (1798) AMW = Austin/Morris/Wolseley U = transmission type (manual) H = high compression which was 8.2:1 in the UK for this engine which was fitted to Mk1 cars from 1964 - 1968. These engines had the heavier 4 ring pistons and a range of 3 different camshafts, the last being the same lift and timing as used on Mk11 cars but all without the mechanical drive for the fuel pump. The cylinder heads had the smaller inlet valves as used on earlier MGBs. The other two numbers you quote would appear to be unique to Australasia. Hopefully someoner can fill in the gaps for you. The only clue I have is that the "C" in the first example could indicate it is an early Mk11 engine but I am not sure. regards David Hi all, I hope you can help me, I have three engine/gearboxes I will need to overhaul one for my Ute so I am looking to try and understand the engine number sequence and what it means, of course your advice as to which engine would be the better doner.

David,
Thanks that helps, if as I suspect the eninge in question was the original from the ute I should probably overhaul that one. This first engine # I quoted was an automatic gearbox not sure if that helps any.

THIS is quite a handy read. Unfortunately, it doesn't add anything to the Oz numbers. Agree with David, the "Y" must indicate local production. "YE" might be an Exchange engine? I think you'll also find that the crank end is different on the automatic engine, so save that one to last. Chris.

Hi all! Didn't we have a thread on Australian engine numbers once? Or is my memory failing?
I could be wrong of course:-) I'm not into Australian engines, only know mark 1 started with 18 AMW... and mark 2 with 18 H... (English production)
However, I do have a SP (?) workshop manual, which I believe is printed in Australia. It does in deed have various specs for Australian and English production in separate "Data"- chapters.
I will find it, and check it out:-)
Regards, Tommy

Hi folks that made for some interesting reading I think I will stick with the orginal engine and return the utility to manual, so if anyone in Perth Australia needs any secondhad engine /gearbox parts contact me.
