Post subject:  Which 1275 to modify???
Hi guys, I have just picked up another moke for parts (collecting next weekend). So I will have 2 Californian mokes, both 1275 models, one is late 78 and the other is late 79. I think there is a difference between the engines, the earlier one is a thin flange block and the later one has a thick flange block.
I will keep one of the mokes original but will part the other one. To much rust to recover.
Which engine would be the better one to build a strong modified grunt box? Stroker 7 port or something.

Either 1275 block will be fine.
Even a thin flange 1275 block is more rigid than a thick flange 1275S one.

Wouldn't you just keep the correct motor with the car your keeping original?

That is the preferred way I want to go.

Why would a late Californian have a thin flange block anyway?

Should they both be thick flange? Does anyone one now what engine prefix should be in it?

They are both late mokes but are before the galv body. Both have fuel fillers on the top of the side box.

All 1275 blocks from ~1969?-1970 on were thick flange. No idea of the engine numbers for a late 70s Moke though.

I believe the very last (~1981?) gal Mokes had a 1275 A+ motor, we put one in Barney the pretend S.

[edit] Barney's A+ motor was a 12H706AAZ one

I have a moke thick flange 1275 block in my 63 mini. It's engine number is 1204 ****. Not sure what year it is though.

The 1204 block is out of the Export Moke from 72-73.
The late Mokes from 78 to 82 with the 1275 motor have a 12H902 motor and maybe a 12H905 on the last ones. There might be another couple of prefixes as well.

A thin flange block is going to be a 12YD/Ta/H from 67/68.

PM John Sneddon on here. He has a full list of Mini and Moke body and engine number data.

From the Moke forum-
1275 engines in 1981 Mokes should have a 12H706AAZ engine prefix.

Why would the prefix numbers suddenly go backwards? Especially backwards to an existing Mini 1275GT prefix? :mrgreen:

No idea, but the 706AAZ is an A+ block, the others are not.
Don't these UK sourced numbers just indicate the odds and ends fitted? eg alternator, emissions gear or not, etc?

[edit]
Seems common to late Mokes-
