Mish's 1275GT Build
Discussion
Hi there,
here is my rebuild of My 1980 Clubman 1275GT Mini
here is what it looked like before the rebuild
Since then have removed the engine that was in it and replaced it with the engine out of a 1987 Austin Metro mayfair. this is the engine before reconditioning
Since then i have fully rebuilt this engine, started by disassembling and inspecting everything, decided to rebore the block to .30" and have it acid dipped. After that i brought some Mehle pistons to go with new rebore.
this photo is after i painted the block with VHT engine enamel and fitted the new pistons, as you will notice later on also replaced frost plugs and oil bungs. You will also notice that i have replaced the oil pump and water pump
I also had the head crack tested and planed, aswell as $500 worth of other work (bronze valve guides, unleaded seats) also spent many hours grinding head to david vizard spec's (bare in mind it was my first go at all this)
as you will also notice i have respayed the head with 1000 degree thermal paint.
Have had the cam that came with the metro engine reground by kelford cams with a fast road grind
here is a photo with the head now on the block
after this i have rebuilt the gearbox and differential replacing all bearings and seals aswell as new baulk rings. Also have replaced factory differential with a minisport crosspin diff
Here is a photo with my 1.5 ratio roller rockers showing
i now have the engine complete have just gone and spent alot of money on some nice ignition components
just waiting for the mini to get back from the painters and will be ready to put the engine in.
Update 08/09
its painted!! about time lol.. just gotta wait till they put the glass back in it etc then pick it up friday

Hi can only agree to the above comments very nice job, I like the crome valve cover, fits perfect with the age of the car, will you fit a brake servo? or run it, as is?
good luck with the start up that is a BIG moment, when engine kicks into life, after such a big rebuilt.
A friend of mine, has just found, a very early Clubman, with all the rare bits inplace, hydro suspension - black covers on the rubber seal on sill (same as Cooper S MK III) - vinyl on rearbins, same colour as enterior - Black vinyl on A posts - etc.
The car is from Sweden, so it has electric screen washer, rear seatbelts, generator - and steering columm lock, its so early, so it has a MK II boot handle.

would anyone be able to tell me an estimated HP output for my engine will be just looking into changing the choke etc on the carb and need to know a estimated HP?
Looks nice. Is that a swan neck manifold, or a very short one?1310, with a fast road cam and verto clutch and non close gears.
Any idea what timing the cam is. Fast road, I'm assuming something like a piper 270 or a kent 276. I'd say you're looking at about 85 flywheel horsepower. Bear in mind that the MG metro (72hp) had a 252/268 cam, which is hotter than a gran-cam.
It depends on your compression ratio as well. I'd want to go around the 10.5:1 mark on 95 octane fuel.
What you will find critical is what final drive to use. As a tip, I was running a 3.44 on a very similar engine on 19.5" diameter tyres (10") and first gear of an A+_box was pretty useless. If I had to use a non CR box, I'd go for a 3.2 to get a useable first. Although a 3.7 with special tuning ratios is the real deal.
I think you'll find 38mm chokes will do the job.
Well i have been busy!.
The mini is all running, still needs to be tuned, but its been reg'd and warranted and certified
Have recently purchased some new carpets and dynamat sound deadning. btw thanks Zac for hooking me up.
some recent progress photo's
Todays work!
