The BL Mini 1275 GT should have been the best Mini ever produced. Why was it watered down and given a bog standard ADO16 engine? I’ve never understood this for many reasons. Firstly, they built the Austin / Morris 1300 GT alongside it and this car was tuned much higher. The 1300 GT engine had the 12G1817 tuftrided crankshaft with better connecting rods that can be recognised by the miniature beam half-way down the shank. It also had twin carburetion, LCB exhaust system and the big valve 12G940 cylinder head.

Some very early 1275 GT cars had these tuftrided S-type cranks (some which had the 1300 centre main bearing widths) and Midget rods.

Post 1975 the casting hole was deleted from 1300 blocks. These blocks had more rigidity than the S blocks because of the solid tappet chest and the increased strength in the centre main area.

No reason in the world why the last 1275 GT cars could not have been the best Minis ever.

What do others think?

Could the perceived market have been young men who would struggle to afford insurance with such a tuned engine?

Docka, a very good point you have made. I never thought of that reason. And the larger 1300 GT fitted the older age group :)

Alan the obvious reason was MONEY :oops: :oops: , when it became BL they started to try and save money :oops: :oops: ,Cheap and Nasty as it became :oops: :oops: , My opinion its hey day was 1966/67 they had ironed out all the faults in the entire range :D :D The 10 inch wheeled 1275 were the last of the good cars , :D :D Then downhill all the way :( :( :( .

Thank you Goff, your honest take and view has been endorsed by friends who have so much knowledge on these cars but never post on the open forum :)

I believe the 1275GT was really intended to replace the 998cc Cooper rather than the 1275 S, partly because BL under Stokes resented paying Cooper royalties for the name and because of the higher insurance rates that came with the Cooper badge.....although the detuned 1275 gave similar performance to the Cooper it seems many insurance companies still loaded the 1275GT in a fairly high ins group. Shame they never did a production 1275GTS as Alan suggested using the 1300GT engine but if you read 'BL's History' it is full of so many missed opportunities!

Thank you Martin, for your mention of missed opportunities. Here is something for all of us to reflect on. In the early seventies I had a 970 Cooper S and my brother had an Mk1 Ford Escort Twin Cam. Guest what? My Cooper was classed higher and had about 50% BHP less than the Escort car. The Cooper name was there downfall because in that period a bog standard Riley Kestrel was more powerful :)

Interesting opening to this thread as my 1275GT ..year 77 built & was UK registered in 78.. yet somehow in the past it was fitted with a 1300GT solid block engine & a hot cam.. i have put it back onto twin HS2,s & it looks a lot better on 10inch wheels..yes its not a car for the "Purist".. today my GT £ value allows it to be used as a Mini should be .. Rev Up & Go have Fun!

I think they should have marketed that model simply as a 1275 Clubman. Using the GT in it's title did it no favours and was possibly even a dumb move.

We, more or less, got the same model here, but not until 1978 and was in fact the run-out Mini Model, it was marketed and sold as a 1275 LS Mini.

They perhaps should have sat on the 'GT' in the name for a few years, then released a 1275 GT Model that did have a tweaked sportier engine along the lines of a modernised Cooper S unit perhaps.

One other small point about the 1275GT that I don't think has been mentioned is that it was aerodynamically poorer that the original Mini which itself was no aerodynamic guru's dream car! More grunt was needed to achieve the same result. Not exactly a step forward in bringing out the model although of course it did have more space under the bonnet.

Another point. Was the 1275 GT (or Clubman) front more pleasing to the eye or less pleasing? Maybe I am biased (or just bl.....y old!) but for me the 1275GT front never cut the mustard as well as the original Mini front did. Pays your money, takes your choice I suppose.
