Appreciate the pistons (and head) will need changing, just wasn't sure if 'the block' would be ok. |

Block would be the same, but, fitting an A+ dizzy is a hassle. If going Megajolt or similar, there will be no issues. On 13th Jul, 2012 Ben H said:

Assuming 1275, there is a void in the casting above the centre main bearing on "A" blocks which makes them weaker in that area.

However, when I asked the question, the general view was that it is only a problem on high RPM motors and turbos usually are not built for high RPM. As well as the dizzy mount being different as Vegard says, you will need a special bracket to fit an alternator as the bosses on the front of the block are further across to take a dynamo. but 1000s came with a altenator as standard so chances are you have one allready. Infact didnt all 1275 'non coopers' come with one? |

There are a few blocks around which does not have that hole above the centre main bearing. |

That hole most likely will improve horespower though! Edited by Vegard on 31st Mar, 2009. On 13th Jul, 2012 Ben H said:

Infact didnt all 1275 'non coopers' come with one? Maybe later ones but I have two early "A" 1275 blocks (with the hole above the centre main bearing) with bosses for dynamos :) All the differences are minor and can be worked around, and as blocks become scarcer, we'll all have to...
