Hi all
What year did the A+ engine come into existence in minis and mokes?
Is their a cut off year between the A series & A+ series?

Is there A series 1275 motors as compared to A+ series 1275 motors?

its a mixed thing really, australian mini's never got a+ but the uk 1275gt got a+ block arround 1979, these cars were a mix of parts, usually a+ block and gearbox but non a+ head. from what ive read most of these ars went export(not uk home market), after the gt ended production in (1981?) it must have dissappeared from minis till (1990? ) when the cooper was released. 81 - 90 it was still being used in the mg metro and metro VDP and the (montego/mastero 1300?) (not austin metro)
The 998 a+ came in mis 80's sometime...i think
so no, it didnt kinda come in overnght, im not sure about the moke though.

In Aus later Mokes, post 78 until the end in 82, had A+ gear boxes but original A engines.

All Australian delivered minis and Mokes had A engines, not A+.

In the UK the 1275 A+ engine disappeared out of mini production, but continued in Metros during the 80s until minis once again got 1275 engines in 1990. I believe all metro engines were A+ until they changed to K-series.

im sure the lower range metros never got the a+

Not the 1275 A+ but I was pretty sure they had the 998 A+

fair call, dunno about the 998, when did that come into production? wasent in minis in 82, so i assume 84 allong with the discs?

MY 81 moke has A+ gearbox and I presumed A+ 1275 motor.
I presumed this because it has an A+ dist drive.
engine no 12H706AA7032314

yup, thats a 1275 a+ then, probably dosent have an a+ head though, is the area behind your themostat housing flat?

I disagree. I have two 1980 Mokes with their original '12H' motors. They are both A+. Dead give-away on the A+ is the dizzy and the timing cover vent.

and the ribbing in the front of the block....anyone got an a+ head they are sculpted behind the thermostat insted if flat...

interesting i have a 1275 A+ motor in my 77 clubman s i was told this by a reputable mini shop.. and i think its the original motor. how can you tell its a A+? and the area behind the themostat housing is flat. also my themostat housing points towards the back of car which is different to other minis i have seen.

whats the engine number? and is the dizzy held in by a "fork" or a clamp? also the area on the front of the block is ribbed on an a+. 77 clubman would NOT hav had a standard A+, or a 1275 for that matter.

oh, 1275 thermostats point a diff direction to smallbore ones...pain in the....

Barney now has a 1293 A+ motor in, came out of an 81 Oz Moke.
Not sure what head it had originally but it's wearing a 1275LS one at the moment.
Modified, of course.....

I've got the A+ dist drive dog, a vent can on my timing cover.
What sort of ribbing does an A+ head have?
Anybody got a pic and on that subject how do you insert a pic into your message?
