Hello again! Ive been busy, Here is my progress so far.
First thing I did was to cut open the breather tube and make a small plate to weld on.



Once the welding was cleaned up and it was given a coat of paint it looked ok.


Ive temp fitted it for now just to keep the timing gear clean.


Next I fitted the flywheel housing.


And then this red ring thingy.


Lightened flywheel from Mini Spares, Clutch and top clamping plate thing.




Now im not sure about this but some folk reckon you can get an extra 10 BHP with this colour.


This bit was next, All cleaned up of course.


Nasty bell housing. With the wrong type of plunger, but the other bits will be fine after a good clean.


Ta Da!!!


And a coat of primer on the cover.


Then the water pump, Mini Spares high capacity type.


Sorted.

Looking good, keep up the good work

Ive painted the bell housing and copper eased the plunger. Then I fitted it to the engine.




Also the Head has arrived. Its been away getting ported and polished. I was buying a MED rally spec head off a mate because he was going the 7 port route. Well thats all fallen through So I sent my 12g940 to get sorted. This is how it looks now.


Skimmed, ported, polished and all the valve gear fitted.


The chambers were ground back a wee bit to get rid of most of the rough casting marks.


The ports are now as big as can be done. They had to sleave the push rod guides to get the maximum size. The pics dont really show how much work has been done inside the ports, but ive had my fingers in there and they are smooooooooth. Also the exhaust ports were widened to match the LCB manifold and then polished.



The last pic is the new rocker cover. Mmmmmm blue.


Hope it all works well. Might of been better just buying a prebuilt engine. This is now a very expensive build. (£1900) so far.

C'mon! That engine deserves a proper LCB! Not such a cheapo welded-triangle pile of pipes....

Good build - keep up the good work!

Yeah I know Its not the best!!! Its one my mate took off his rally clubman. He had it made specifically for his rally car. He then turned it on its roof on stage 5 of the snowman last year. But it works quite well even for a home made jobby. Once the engine is run in I will look at changing the whole system.
Thanks for looking.

Nice work man, that head's a peice of art!

A prebuilt engine would have been cheaper, but you now know your engine inside out. Counts for a lot, in my opinion.

Anyway, what's your plan on the ignition front? Megajolt, Aldon, 123?

Watching this, should go well.

Thanks. Its my first proper build. I rebuilt the MG metro engine thats in the car at the mo, but this was a bit more of a challange. This is the mini its going in.

Im going to stick with the Metro electronic ignition for now. My wallet is empty. (Son just started Uni). If the wife ever finds out how much ive spent im a dead man.

Are those center strap bolts the correct grade?

Thanks for the link. Im going to transfer the electronic ignition from the MG engine in "Haggis " to the new engine and see how it runs. I recon it will be ok for now.

[AndyMiniMad.]

You know its funny you should ask that because i had the exact same thought when they arrived. But I phoned Jonspeed who supplied the strap and the bolts and they said they were the correct ones!!

[AndyMiniMad.]

Ok so the head is on and torqued down. Ive stripped all the gubbins off the 1275 in "Haggis" and will wheek it out at the weekend. The last job to do on the 1380 is the cam timing. Ive ordered the timing disk thingy from Mini Spares and hope its a fairly simple job to time in the cam. It needs to be timed in at 104.5 deg acording to the info that came with the cam. If all goes well the enginbe should be in at some stage next week.
