970 block


  1. imported post

    Just had a look at my AEG 151 block pictures and you're right, it has had a lot machined off the top, about two to three mm. Assuming the crank is a standard stroke 970 [61.9mm] maybe someone has built the motor with the shorter 1071/1275 conrods and then skimmed the block down to suit. I would think you would be into water pump to cylinder head fouling problems as well.

    It always amazes me when people bid serious cash without knowing anything about bore/crank bearing sizes or even seeing the damage the 'spun bearing' has done!…………Assuming the bids are genuine off course:shock::shock:.


    picture of 151 block with the 'lugs' Gray refers too.

  2. What do we make of this one then.

    some tuners overbored the 970 blocks to it's limits and than destroked them to stay within class displacement specs.maybe that explains way it would becut down so much.

    the mention it might be a formula junior block, going by the flat face of the block below the oil pressure valve is right off

    the flat face just isn't there

    OK now for this weeks instalment:)[url=http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=230304590776&ssPageName=STRK:MEWA:IT&ih=013]http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=230304590776&ssPageName=STRK:MEWA:IT&ih=013[/url]could be one of the later thick flange replacements bmc did but cannot make out any of the stamps on the deck surface, looks sleeved as well, good crank by the sounds.

    The same buyer also bought this head last year:





    They are both 12A185 but they are a little different.

    My old June 1963 S still had it's 185 – perfectly intact – albeit modified in 'the day'. Phil Hepworth rebuilt the engine – the water galleries had been enlarged and cleaned out.

    Ran the car on super plus with led additive and octane booster. Also used 4 blade fan, 2 core super rad and 'water wetter'. Never ran hot.

    I would guess that if one has made it this far – 45 years – ought to stand the chance of being a good'un.

    I'd guess whether you retro fit a 185 head to a 1071 depends on how important originality to it's 1st day registered is. Given though that if the car has already lost it's 185, I'd stick a 163 on top – after all, in Oct 1963 on that would have been the dealer option for a car with a cracked 185. By 1969 when your car had then cracked 3 or 4 163's, you could at last have a proper head – 940.

    They cracked in the 60's on top quality fuel so how long would one last today even with a performance additive especially as unleaded burns at a higher temperature than unleaded?

    Let us not forget that BMC replaced it because it was a flawed design.

    Have to say that I have thought that as well.

    I certainly wouldn't pay hard earnedmoney for a185 (or any head prone to problems) that has not been crack tested.

    Still if it isn't any good it can always go back on eBay 😛
